Palearctic realm
–
The Palearctic or Palaearctic is the largest of the eight biogeographic realms constituting the Earths surface. It consists of Europe, Asia north of the foothills of the Himalayas, North Africa, the Palearctic realm comprises the smaller terrestrial ecoregions of the Euro-Siberian region, the Mediterranean Basin, the Sahara and Arabian Deserts, and Western, Central and East Asia. The Palaearctic realm also has rivers and lakes, forming several freshwater ecoregions. Some of the rivers were the source of water for the earliest recorded civilizations that used irrigation methods, the Palearctic realm includes mostly boreal/subarctic-climate and temperate-climate ecoregions, which run across Eurasia from western Europe to the Bering Sea. South of the taiga are a belt of temperate broadleaf and mixed forests and this vast Euro-Siberian region is characterized by many shared plant and animal species, and has many affinities with the temperate and boreal regions of the Nearctic ecoregion of North America. Many zoologists consider the Palearctic and Nearctic to be a single Holarctic realm, the Palearctic and Nearctic also share many plant species, which botanists call the Arcto-Tertiary Geoflora. The Mediterranean basins mosaic of Mediterranean forests, woodlands, and scrub are home to 13,000 endemic species. Formerly the region was covered with forests and woodlands, but heavy human use has reduced much of the region to the sclerophyll shrublands known as chaparral, matorral, maquis. Conservation International has designated the Mediterranean basin as one of the biodiversity hotspots. A great belt of deserts, including the Atlantic coastal desert, Sahara desert, Central Asia and the Iranian plateau are home to dry steppe grasslands and desert basins, with montane forests, woodlands, and grasslands in the regions high mountains and plateaux. In southern Asia the boundary of the Palearctic is largely altitudinal, the middle altitude foothills of the Himalaya between about 2000–2500 m form the boundary between the Palearctic and Indomalaya ecoregions. East Asia was not much affected by glaciation in the ice ages, the mountains of southwest China are also designated as a biodiversity hotspot. In Southeastern Asia, high mountain ranges form tongues of Palearctic flora and fauna in northern Indochina, isolated small outposts occur as far south as central Myanmar, northernmost Vietnam and the high mountains of Taiwan. One bird family, the accentors is endemic to the Palearctic region, the Holarctic has four other endemic bird families, the divers or loons, grouse, auks, and waxwings. There are no endemic mammal orders in the region, but several families are endemic, Calomyscidae, Prolagidae, contributions to the zooarchaeology of Iceland, some preliminary notes.

Physiographic regions of the world
–
This foundational model, which Fenneman used to classify the United States, was the basis for similar classifications of other continents later, and is still considered basically valid. During the early 1900s, the study of geomorphology was termed physiography. In current usage, physiography still lends itself to confusion as to which meaning is meant, for the remainder of this article, emphasis will remain on the more geomorphological usage, which is based upon geological landforms, not on climate, vegetation, or other non-geological criteria. For the purposes of mapping, landforms are classified according to both their geologic structures and histories. A maturely dissected plateau may grade without a break from rugged mountains on the one hand to mildly rolling farm lands on the other, so also, forms which are not classified together may be superficially similar, for example, a young coastal plain and a peneplain. In a large number of cases, the lines are also geologic lines. The history of itself is at best a complicated effort. Much of the complications arise from how the term has evolved over time, in 1848, Mary Somerville published her book Physical Geography which gave detailed descriptions of the topography of each continent, along with the distribution of plant, animals and humans. This work gave impetus to further works along the field, in Germany, Oscar Peschel in 1870, proposed that geographers should study the morphology of the Earths surface, having an interest in the study of landforms for the development of human beings. As the chair of geography in Bonn, Germany, Ferdinand von Richthofen made the study of landforms the main field for himself. Elsewhere, Thomas Henry Huxleys Physiography was published in 1877 in Britain, shortly after, the field of physical geography itself was renamed as physiography. In conjunction with these advances in physiography, physically and visually mapping these descriptive areas was underway as well, the early photographers and balloonists, Nadar and Triboulet, experimented with aerial photography and the view it provided of the landscape. The block diagrams of Fenneman, Raisz, Lobeck and many others were based in part upon both aerial photography and topographic maps, giving an oblique birds-eye view, by 1901, there were clear differences in the definition of the term physiography. In England, physiography is regarded as the introduction to science in general. It is made to include the elements of physics, chemistry, astronomy, physical geography, and geology, in America, the term has a somewhat different meaning. It is sometimes used as a synonym for physical geography, and is defined as the science which describes. Although the term has since been limited by some writers to one part of the subject. In the stricter sense, physical geography is part of geography which involves the processes of contemporary change in the crust

Plain
–
In geography, a plain is a flat, sweeping landmass that generally does not change much in elevation. Plains occur as lowlands along the bottoms of valleys or on the doorsteps of mountains, as coastal plains, and as plateaus or uplands. In a valley, a plain is enclosed on two sides but in other cases a plain may be delineated by a complete or partial ring of hills, where a geological region contains more than one plain, they may be connected by a pass. Coastal plains would mostly rise from sea level until they run into elevated features such as mountains or plateaus, plains are one of the major landforms on earth, where they are present on all continents, and would cover more than one-third of the world’s land area. Plains may have formed from flowing lava, deposited by water, ice, wind, or formed by erosion by these agents from hills. Plains would generally be under the grassland, steppe, savannah or tundra biomes, in a few instances, deserts and rainforests can also be plains. Structural plains are relatively undisturbed horizontal surfaces of the Earth and they are structurally depressed areas of the world that make up some of the most extensive natural lowlands on the Earths surface. Erosional plains have been leveled by various agents of such as running water, rivers, wind and glacier which wear out the rugged surface. Plain resulting from the action of these agents of denudation are called peneplains while plains formed from wind action are called pediplains, depositional plains formed by the deposition of materials brought by various agents of transportation such as rivers, wind, waves, and glaciers. Their fertility and economic relevance depend greatly on the types of sediments that are laid down, flood plain, adjacent to a stream, river, lake or wetland that experiences occasional or periodic flooding. Scroll plain, a plain through which a river meanders with a low gradient. Lacustrine plain, a plain that originally formed in a lacustrine environment, lava plain, formed by sheets of flowing lava. Glacial plains, formed by the movement of glaciers under the force of gravity, Sandur, sandar consist mainly of stratified gravel and sand. Till plain, a plain of glacial till that forms when a sheet of ice becomes detached from the body of a glacier. Till plains are composed of unsorted material of all sizes, abyssal plain, a flat or very gently sloping area of the deep ocean basin. Planitia, the Latin word for plain, is used in the naming of plains on extraterrestrial objects, such as Hellas Planitia on Mars or Sedna Planitia on Venus

Europe
–
Europe is a continent that comprises the westernmost part of Eurasia. Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, yet the non-oceanic borders of Europe—a concept dating back to classical antiquity—are arbitrary. Europe covers about 10,180,000 square kilometres, or 2% of the Earths surface, politically, Europe is divided into about fifty sovereign states of which the Russian Federation is the largest and most populous, spanning 39% of the continent and comprising 15% of its population. Europe had a population of about 740 million as of 2015. Further from the sea, seasonal differences are more noticeable than close to the coast, Europe, in particular ancient Greece, was the birthplace of Western civilization. The fall of the Western Roman Empire, during the period, marked the end of ancient history. Renaissance humanism, exploration, art, and science led to the modern era, from the Age of Discovery onwards, Europe played a predominant role in global affairs. Between the 16th and 20th centuries, European powers controlled at times the Americas, most of Africa, Oceania. The Industrial Revolution, which began in Great Britain at the end of the 18th century, gave rise to economic, cultural, and social change in Western Europe. During the Cold War, Europe was divided along the Iron Curtain between NATO in the west and the Warsaw Pact in the east, until the revolutions of 1989 and fall of the Berlin Wall. In 1955, the Council of Europe was formed following a speech by Sir Winston Churchill and it includes all states except for Belarus, Kazakhstan and Vatican City. Further European integration by some states led to the formation of the European Union, the EU originated in Western Europe but has been expanding eastward since the fall of the Soviet Union in 1991. The European Anthem is Ode to Joy and states celebrate peace, in classical Greek mythology, Europa is the name of either a Phoenician princess or of a queen of Crete. The name contains the elements εὐρύς, wide, broad and ὤψ eye, broad has been an epithet of Earth herself in the reconstructed Proto-Indo-European religion and the poetry devoted to it. For the second part also the divine attributes of grey-eyed Athena or ox-eyed Hera. The same naming motive according to cartographic convention appears in Greek Ανατολή, Martin Litchfield West stated that phonologically, the match between Europas name and any form of the Semitic word is very poor. Next to these there is also a Proto-Indo-European root *h1regʷos, meaning darkness. Most major world languages use words derived from Eurṓpē or Europa to refer to the continent, in some Turkic languages the originally Persian name Frangistan is used casually in referring to much of Europe, besides official names such as Avrupa or Evropa
5.
Mountain
–
A mountain is a large landform that stretches above the surrounding land in a limited area, usually in the form of a peak. A mountain is steeper than a hill. Mountains are formed through tectonic forces or volcanism and these forces can locally raise the surface of the earth. Mountains erode slowly through the action of rivers, weather conditions, a few mountains are isolated summits, but most occur in huge mountain ranges. High elevations on mountains produce colder climates than at sea level and these colder climates strongly affect the ecosystems of mountains, different elevations have different plants and animals. Because of the less hospitable terrain and climate, mountains tend to be used less for agriculture and more for resource extraction and recreation, the highest mountain on Earth is Mount Everest in the Himalayas of Asia, whose summit is 8,850 m above mean sea level. The highest known mountain on any planet in the Solar System is Olympus Mons on Mars at 21,171 m, there is no universally accepted definition of a mountain. Elevation, volume, relief, steepness, spacing and continuity have been used as criteria for defining a mountain, whether a landform is called a mountain may depend on local usage. The highest point in San Francisco, California, is called Mount Davidson, notwithstanding its height of 300 m, similarly, Mount Scott outside Lawton, Oklahoma is only 251 m from its base to its highest point. Whittows Dictionary of Physical Geography states Some authorities regard eminences above 600 metres as mountains, in addition, some definitions also include a topographical prominence requirement, typically 100 or 500 feet. For a while, the US defined a mountain as being 1,000 feet or taller, any similar landform lower than this height was considered a hill. However, today, the United States Geological Survey concludes that these terms do not have technical definitions in the US, using these definitions, mountains cover 33% of Eurasia, 19% of South America, 24% of North America, and 14% of Africa. As a whole, 24% of the Earths land mass is mountainous, there are three main types of mountains, volcanic, fold, and block. All three types are formed from plate tectonics, when portions of the Earths crust move, crumple, compressional forces, isostatic uplift and intrusion of igneous matter forces surface rock upward, creating a landform higher than the surrounding features. The height of the feature makes it either a hill or, if higher and steeper, major mountains tend to occur in long linear arcs, indicating tectonic plate boundaries and activity. Volcanoes are formed when a plate is pushed below another plate, at a depth of around 100 km, melting occurs in rock above the slab, and forms magma that reaches the surface. When the magma reaches the surface, it builds a volcanic mountain. Examples of volcanoes include Mount Fuji in Japan and Mount Pinatubo in the Philippines, the magma does not have to reach the surface in order to create a mountain, magma that solidifies below ground can still form dome mountains, such as Navajo Mountain in the US

Landform
–
A landform is a natural feature of the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography, landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure, and soil type. Oceans and continents exemplify the highest-order landforms, landform elements are parts of a high-order landforms that can be further identified and systematically given a cohesive definition such as hill-tops, shoulders, saddles, foreslopes and backslopes. Some generic landform elements including, pits, peaks, channels, ridges, passes, pools, Terrain is the third or vertical dimension of land surface. Topography is the study of terrain, although the word is used as a synonym for relief itself. When relief is described underwater, the term bathymetry is used, in cartography, many different techniques are used to describe relief, including contour lines and TIN. Elementary landforms are the smallest homogeneous divisions of the land surface and these are areas with relatively homogeneous morphometric properties, bounded by lines of discontinuity. A plateau or a hill can be observed at various scales ranging from few hundred meters to hundreds of kilometers, hence, the spatial distribution of landforms is often scale-dependent as is the case for soils and geological strata. A number of factors, ranging from plate tectonics to erosion and deposition, can generate, landforms do not include man-made features, such as canals, ports and many harbors, and geographic features, such as deserts, forests, and grasslands. Many of the terms are not restricted to refer to features of the planet Earth, examples are mountains, hills, polar caps, and valleys, which are found on all of the terrestrial planets. The scientific study of landforms is known as geomorphology, landforms may be extracted from a digital elevation model using some automated techniques where the data has been gathered by modern satellites and stereoscopic aerial surveillance cameras. Until recently, compiling the data found in data sets required time consuming. The most detailed DEMs available are measured directly using LIDAR techniques, geomorphology Land List of landforms Open-geomorphometry project Terrain Open-Geomorphometry Project

Highland
–
The term highland or uplands is used to denote any mountainous region or elevated mountainous plateau. Generally speaking, upland tends to refer to ranges of hills, Highland is usually reserved for ranges of low mountains. Probably the most known highlands in the anglosphere are the Scottish Highlands in the United Kingdom, the Highland council area is a local government area in the Scottish Highlands and Britains largest local government area. Many countries have areas that are officially or unofficially referred to as highlands, other than Scotland, these include parts Ethiopia, Kenya, Eritrea, Yemen, Nigeria, Papua New Guinea, Syria, Cantabria and Nova Scotia. The highlands in Australia are often above the elevation of 500 metres and these areas often receive snowfalls through winter. Most of the lead up to large alpine or sub-alpine mountainous regions such as the Australian Alps, Snowy Mountains, Great Dividing Range, Northern Tablelands. The most mountainous region of Tasmania is the Central Highlands area, many of these areas are highly elevated alpine regions. A spine of mountains runs the length of the island of New Guinea, the highlands of Iceland cover about 40% of the country and are mostly inhospitable to humans. They are generally referred to as land above 500 meters, additionally, the mountainous natural region of the Thai highlands is found in Northern Thailand. The Cameron Highlands are an area and hill station in Northern Malaysia. Shillong in India in the state of Meghalaya is a station which is surrounded by highlands. Officers of the British Raj referred to Shillong as The Scotland of the East, Highland continents – or terrae – are areas of topographically unstable terrain, with high peaks and valleys. They resemble highlands on Earth, but the term is applied to larger areas on other planets. They can be found on Venus, Mercury, Mars and the Moon

Pyrenees
–
The Pyrenees is a range of mountains in southwest Europe that forms a natural border between France and Spain. For the most part, the main crest forms a divide between France and Spain, with the microstate of Andorra sandwiched in between. The Crown of Aragon and the Kingdom of Navarre have historically extended on both sides of the range, with smaller northern portions now in France and larger southern parts now in Spain. The demonym for the noun Pyrenees in English is Pyrenean, in Greek mythology, Pyrene is a princess who gave her name to the Pyrenees. The Greek historian Herodotus says Pyrene is the name of a town in Celtic Europe, Hercules, characteristically drunk and lustful, violates the sacred code of hospitality and rapes his hosts daughter. Pyrene gives birth to a serpent and runs away to the woods, alone, she pours out her story to the trees, attracting the attention of wild beasts who tear her to pieces. After his victory over Geryon, Hercules passes through the kingdom of Bebryx again, and all the rock-cliffs and wild-beast haunts echo back Pyrene. … The mountains hold on to the name through the ages. Pliny the Elder connects the story of Hercules and Pyrene to Lusitania, the Spanish Pyrenees are part of the following provinces, from east to west, Girona, Barcelona, Lleida, Huesca, Navarra and Gipuzkoa. The French Pyrenees are part of the following départements, from east to west, Pyrénées-Orientales, Aude, Ariège, Haute-Garonne, Hautes-Pyrénées, the independent principality of Andorra is sandwiched in the eastern portion of the mountain range between the Spanish Pyrenees and French Pyrenees. Physiographically, the Pyrenees may be divided into three sections, the Atlantic, the Central, and the Eastern Pyrenees, together, they form a distinct physiographic province of the larger Alpine System division. In the Western Pyrenees, from the Basque mountains near the Bay of Biscay of the Atlantic Ocean, at the eastern end on the southern side lies a distinct area known as the Sub-Pyrenees. On the French side the slopes of the range descend abruptly. The Pyrenees are older than the Alps, their sediments were first deposited in coastal basins during the Paleozoic and Mesozoic eras, the intense pressure and uplifting of the Earths crust first affected the eastern part and moved progressively to the entire chain, culminating in the Eocene Epoch. The eastern part of the Pyrenees consists largely of granite and gneissose rocks, the massive and unworn character of the chain comes from its abundance of granite, which is particularly resistant to erosion, as well as weak glacial development. Low passes are lacking, and the roads and the railroads between France and Spain run only in the lowlands at the western and eastern ends of the Pyrenees. A notable visual feature of mountain range is La Brèche de Roland, a gap in the ridge line. Coal deposits capable of being profitably worked are situated chiefly on the Spanish slopes, the open pit of Trimoun close to the commune of Luzenac is one of the greatest sources of talc in Europe

Bay of Biscay
–
The Bay of Biscay /ˈbɪskeɪ, -ki/ is a gulf of the northeast Atlantic Ocean located south of the Celtic Sea. It lies along the western coast of France from Point Penmarch to the Spanish border, the average depth is 1,744 metres and the greatest depth is 4,735 metres. The Bay of Biscay is named after Biscay on the northern Spanish coast, the Bay of Biscay is home to some of the Atlantic Oceans fiercest weather. Large storms occur in the bay, especially during the winter months, up until recent years it was a regular occurrence for merchant vessels to founder in Biscay storms. The International Hydrographic Organization defines the limits of the Bay of Biscay as a line joining Cap Ortegal to Penmarch Point, the southernmost portion is the Cantabrian Sea. The phenomenon of June Gloom is common, in late spring and early summer a large fog triangle fills the southwestern half of the bay, covering just a few kilometres inland. As winter begins, weather becomes severe and these depressions cause severe weather at sea and bring light though very constant rain to its shores. The Gulf Stream enters the bay following the continental shelfs border anti-clockwise, the main cities on the shores of the Bay of Biscay are Bordeaux, Bayonne, Biarritz, Brest, Nantes, La Rochelle, Donostia-San Sebastián, Bilbao, Santander, Gijón and Avilés. The southern end of the gulf is called in Spanish Mar Cantábrico, from the Estaca de Bares, as far as the mouth of Adour river. It was named by Romans in the 1st century BC as Sinus Cantabrorum and also, on some medieval maps, the Bay of Biscay is marked as El Mar del los Vascos. The Bay of Biscay has been the site of famous naval engagements over the centuries. In 1592 the Spanish defeated an English fleet during the eponymous Battle of the Bay of Biscay, the USS Californian sank here after striking a naval mine on June 22,1918. On December 28,1943, the Battle of the Bay of Biscay was fought between HMS Glasgow and HMS Enterprise and a group of German destroyers as part of Operation Stonewall during World War II. U-667 sank on 25 August 1944 in position 46°00′N 01°30′W, when she struck a mine, often specialist groups take the ferries to hear more information. Volunteers and employees of Biscay Dolphin Research regularly observe and monitor cetacean activity from the bridge of the ships on the P&O Ferries Portsmouth to Bilbao route, many species of whales and dolphins can be seen in this area. Most importantly, it is one of the few places where the beaked whales and this is the best study area in the world for beaked whales. Other records in the late 20th century include one off Galicia at 43°00′N 10°30′W in September 1977 reported by a whaling company and another one seen off the Iberian Peninsula. The best areas to see the larger cetaceans lie in the deep waters beyond the shelf, particularly over the Santander Canyon

Ural Mountains
–
The mountain range forms part of the conventional boundary between the continents of Europe and Asia. Vaygach Island and the islands of Novaya Zemlya form a continuation of the chain to the north into the Arctic Ocean. The mountains lie within the Ural geographical region and significantly overlap with the Ural Federal District and they have rich resources, including metal ores, coal, precious and semi-precious stones. Since the 18th century the mountains have contributed significantly to the sector of the Russian economy. As attested by Sigismund von Herberstein, in the 16th century Russians called the range by a variety of names derived from the Russian words for rock and it might have been a borrowing from either Turkic stone belt, or Ob-Ugric. From the 13th century, in Bashkortostan there has been a legend about a hero named Ural and he sacrificed his life for the sake of his people and they poured a stone pile over his grave, which later turned into the Ural Mountains. Possibilities include Bashkir үр elevation, upland or Mansi ур ала mountain peak, top of the mountain, tatischev believes that this oronym is set to belt and associates it with the Turkic verb oralu- gird. Dobrodomov suggests a transition from Aral to Ural explained on the basis of ancient Bulgar-Chuvash dialects, hawks believes that the name goes back to the Bashkir folklore Ural-Batyr. Shumilov suggested a Mongolian origin, Khural Uul, that is, the Evenk geographical term era mountain has also been theorized. Finno-Ugrist scholars consider Ural deriving from the Mansi word urr meaning a mountain, turkologists, on the other hand, have achieved majority support for their assertion that ural in Tatar means a belt, and recall that an earlier name for the range was stone belt. During the next few centuries Novgorodians engaged in fur trading with the population and collected tribute from Yugra and Great Perm. The rivers Chusovaya and Belaya were first mentioned in the chronicles of 1396 and 1468, in 1430 the town of Solikamsk was founded on the Kama at the foothills of the Ural, where salt was produced in open pans. Ivan III of Moscow captured Perm, Pechora and Yugra from the declining Novgorod Republic in 1472, with the excursions of 1483 and 1499–1500 across the Ural Moscow managed to subjugate Yugra completely. The Middle and Southern Ural were still largely unavailable and unknown to the Russian or Western European geographers, the Stroganovs land provided the staging ground for Yermaks incursion into Siberia. Yermak crossed the Ural from the Chusovaya to the Tagil around 1581, in 1597 Babinovs road was built across the Ural from Solikamsk to the valley of the Tura, where the town of Verkhoturye was founded in 1598. Customs was established in Verkhoturye shortly thereafter and the road was made the legal connection between European Russia and Siberia for a long time. In 1648 the town of Kungur was founded at the foothills of the Middle Ural. During the 17th century the first deposits of iron and copper ores, mica, gemstones, iron and copper smelting works emerged
11.
Alps
–
The mountains were formed over tens of millions of years as the African and Eurasian tectonic plates collided. Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrusting and folding into high mountain peaks such as Mont Blanc, Mont Blanc spans the French–Italian border, and at 4,810 m is the highest mountain in the Alps. The Alpine region area contains about a hundred peaks higher than 4000 metres, the altitude and size of the range affects the climate in Europe, in the mountains precipitation levels vary greatly and climatic conditions consist of distinct zones. Wildlife such as live in the higher peaks to elevations of 3,400 m. Evidence of human habitation in the Alps goes back to the Palaeolithic era, a mummified man, determined to be 5,000 years old, was discovered on a glacier at the Austrian–Italian border in 1991. By the 6th century BC, the Celtic La Tène culture was well established, Hannibal famously crossed the Alps with a herd of elephants, and the Romans had settlements in the region. In 1800 Napoleon crossed one of the passes with an army of 40,000. The 18th and 19th centuries saw an influx of naturalists, writers, in World War II, Adolf Hitler kept a base of operation in the Bavarian Alps throughout the war. The Alpine region has a cultural identity. The Winter Olympic Games have been hosted in the Swiss, French, at present, the region is home to 14 million people and has 120 million annual visitors. The English word Alps derives from the Latin Alpes, maurus Servius Honoratus, an ancient commentator of Virgil, says in his commentary that all high mountains are called Alpes by Celts. The term may be common to Italo-Celtic, because the Celtic languages have terms for high mountains derived from alp and this may be consistent with the theory that in Greek Alpes is a name of non-Indo-European origin. According to the Old English Dictionary, the Latin Alpes might possibly derive from a pre-Indo-European word *alb hill, Albania, a name not native to the region known as the country of Albania, has been used as a name for a number of mountainous areas across Europe. In Roman times, Albania was a name for the eastern Caucasus, in modern languages the term alp, alm, albe or alpe refers to a grazing pastures in the alpine regions below the glaciers, not the peaks. An alp refers to a mountain pasture where cows are taken to be grazed during the summer months and where hay barns can be found. The Alps are a crescent shaped geographic feature of central Europe that ranges in a 800 km arc from east to west and is 200 km in width, the mean height of the mountain peaks is 2.5 km. The range stretches from the Mediterranean Sea north above the Po basin, extending through France from Grenoble, the range continues onward toward Vienna, Austria, and east to the Adriatic Sea and Slovenia. To the south it dips into northern Italy and to the north extends to the border of Bavaria in Germany

Carpathian Mountains
–
The Carpathian Mountains or Carpathians are a mountain range system forming an arc roughly 1,500 km long across Central and Eastern Europe, making them the second-longest mountain range in Europe. The Carpathians and their foothills also have many thermal and mineral waters, the Carpathians consist of a chain of mountain ranges that stretch in an arc from the Czech Republic in the northwest through Slovakia, Poland, Hungary and Ukraine to Romania and Serbia. The highest range within the Carpathians is the Tatras, on the border of Slovakia and Poland, the second-highest range is the Southern Carpathians in Romania, where the highest peaks exceed 2,500 m. The divisions of the Carpathians are usually in three sections, Western Carpathians — Czech Republic, Poland, and Slovakia. Eastern Carpathians — southeastern Poland, eastern Slovakia, Ukraine, Romania, the term Outer Carpathians is frequently used to describe the northern rim of the Western and Eastern Carpathians. The most important cities in or near the Carpathians are, Bratislava and Košice in Slovakia, Kraków in Poland, Cluj-Napoca, Sibiu and Braşov in Romania, and Uzhhorod in Ukraine. In modern times, the range is called Karpaty in Czech, Polish, Slovak and Карпати in Ukrainian, Carpați in Romanian, Karpaten in German, Kárpátok in Hungarian and Karpati or Карпати in Serbian. Although the toponym was recorded already by Ptolemy in the 2nd century CE, for instance, Havasok was its medieval Hungarian name, Rus and Romanian chronicles referred to it as Hungarian Mountains. The archaic Polish word karpa meant rugged irregularities, underwater obstacles/rocks, the more common word skarpa means a sharp cliff or other vertical terrain. In late Roman documents, the Eastern Carpathian Mountains were referred to as Montes Sarmatici, the Western Carpathians were called Carpates, a name that is first recorded in Ptolemys Geographia. In the Scandinavian Hervarar saga, which relates ancient Germanic legends about battles between Goths and Huns, the name Karpates appears in the predictable Germanic form as Harvaða fjöllum, inter Alpes Huniae et Oceanum est Polonia by Gervase of Tilbury, has described in his Otia Imperialia in 1211. Thirteenth- to fifteenth-century Hungarian documents named the mountains Thorchal, Tarczal or less frequently Montes Nivium, the northwestern Carpathians begin in Slovakia and southern Poland. They surround Transcarpathia and Transylvania in a semicircle, sweeping towards the southeast. The total length of the Carpathians is over 1,500 km, the highest altitudes of the Carpathians occur where they are widest. The Carpathians cover an area of 190,000 km2 and, after the Alps, although commonly referred to as a mountain chain, the Carpathians do not actually form an uninterrupted chain of mountains. Rather, they consist of several orographically and geologically distinctive groups, the Carpathians at their highest altitude are only as high as the middle region of the Alps, with which they share a common appearance, climate, and flora. The Carpathians are separated from the Alps by the Danube, the two ranges meet at only one point, the Leitha Mountains at Bratislava. The river also separates them from the Balkan Mountains at Orşova in Romania, the valley of the March and Oder separates the Carpathians from the Silesian and Moravian chains, which belong to the middle wing of the great Central Mountain System of Europe

English Channel
–
The English Channel, also called simply the Channel, is the body of water that separates southern England from northern France, and links the southern part of the North Sea to the Atlantic Ocean. It is about 560 km long and varies in width from 240 km at its widest to 33.3 km in the Strait of Dover and it is the smallest of the shallow seas around the continental shelf of Europe, covering an area of some 75,000 km2. The International Hydrographic Organization defines the limits of the English Channel as follows, a line joining Isle Vierge to Lands End. The southwestern limit of the North Sea, the IHO defines the southwestern limit of the North Sea as a line joining the Walde Lighthouse and Leathercoat Point. The Walde Lighthouse is 6 km east of Calais, and Leathercoat Point is at the end of St Margarets Bay. The Strait of Dover, at the Channels eastern end, is its narrowest point and it is relatively shallow, with an average depth of about 120 m at its widest part, reducing to a depth of about 45 m between Dover and Calais. Eastwards from there the adjoining North Sea reduces to about 26 m in the Broad Fourteens where it lies over the watershed of the land bridge between East Anglia and the Low Countries. It reaches a depth of 180 m in the submerged valley of Hurds Deep,48 km west-northwest of Guernsey. The eastern region along the French coast between Cherbourg and the mouth of the Seine river at Le Havre is frequently referred to as the Bay of the Seine. There are several islands in the Channel, the most notable being the Isle of Wight off the English coast. The coastline, particularly on the French shore, is indented, several small islands close to the coastline, including Chausey. The Cotentin Peninsula in France juts out into the Channel, whilst on the English side there is a parallel channel known as the Solent between the Isle of Wight and the mainland. The Celtic Sea is to the west of the Channel, the time difference of about six hours between high water at the eastern and western limits of the Channel is indicative of the tidal range being amplified further by resonance. It was never defined as a border and the names were more or less descriptive. It was not considered as the property of a nation, strangely, before the development of the modern nations, British scholars very often referred to it as Gaulish and the French one as British or English. The name English Channel has been used since the early 18th century. In modern Dutch, however, it is known as Het Kanaal, later, it has also been known as the British Channel or the British Sea having been called the Oceanus Britannicus by the 2nd-century geographer Ptolemy. The same name is used on an Italian map of about 1450, the Anglo-Saxon texts often call it Sūð-sǣ as opposed to Norð-sǣ

British Isles
–
The British Isles are a group of islands off the north-western coast of continental Europe that consist of the islands of Great Britain, Ireland and over six thousand smaller isles. Situated in the North Atlantic, the islands have an area of approximately 315,159 km2. Two sovereign states are located on the islands, Ireland and the United Kingdom of Great Britain, the oldest rocks in the group are in the north west of Scotland, Ireland and North Wales and are 2,700 million years old. During the Silurian period the north-western regions collided with the south-east, the topography of the islands is modest in scale by global standards. Ben Nevis rises to an elevation of only 1,344 metres, and Lough Neagh, the climate is temperate marine, with mild winters and warm summers. The North Atlantic Drift brings significant moisture and raises temperatures 11 °C above the average for the latitude. This led to a landscape which was dominated by temperate rainforest. The region was re-inhabited after the last glacial period of Quaternary glaciation, Ireland, which became an island by 12,000 BC, was not inhabited until after 8000 BC. Great Britain became an island by 5600 BC, Hiberni, Pictish and Britons tribes, all speaking Insular Celtic, inhabited the islands at the beginning of the 1st millennium AD. Much of Brittonic-controlled Britain was conquered by the Roman Empire from AD43, the first Anglo-Saxons arrived as Roman power waned in the 5th century and eventually dominated the bulk of what is now England. Viking invasions began in the 9th century, followed by permanent settlements. Most of Ireland seceded from the United Kingdom after the Irish War of Independence, the term British Isles is controversial in Ireland, where there are objections to its usage due to the association of the word British with Ireland. The Government of Ireland does not recognise or use the term, as a result, Britain and Ireland is used as an alternative description, and Atlantic Archipelago has had limited use among a minority in academia, while British Isles is still commonly employed. Within them, they are sometimes referred to as these islands. The earliest known references to the islands as a group appeared in the writings of sea-farers from the ancient Greek colony of Massalia. The original records have been lost, however, later writings, e. g. Avienuss Ora maritima, in the 1st century BC, Diodorus Siculus has Prettanikē nēsos, the British Island, and Prettanoi, the Britons. Strabo used Βρεττανική, and Marcian of Heraclea, in his Periplus maris exteri, historians today, though not in absolute agreement, largely agree that these Greek and Latin names were probably drawn from native Celtic-language names for the archipelago. Along these lines, the inhabitants of the islands were called the Πρεττανοί, the shift from the P of Pretannia to the B of Britannia by the Romans occurred during the time of Julius Caesar

Jutland
–
Jutland, also known as the Cimbric or Cimbrian Peninsula, is a peninsula of Northern Europe that forms the continental portion of Denmark and the northern portion of Germany. The names are derived from the Jutes and the Cimbri, respectively, jutlands terrain is relatively flat, with open lands, heaths, plains and peat bogs in the west and a more elevated and slightly hilly terrain in the east. Jutland is a peninsula bounded by the North Sea to the west, the Skagerrak to the north, geographically and historically, Jutland comprises the regions of South Jutland, West Jutland, East Jutland and North Jutland. There are several subdivisions and regional names, some of which are still occasionally encountered today. They include Nørrejyllland, Sydvestjylland, Nordvestjylland and Slesvig, historically, Jutland was regulated by the Law Code of Jutland. This civic code covered the Jutland Peninsula from the north of the River Eider to Funen as well as the North Jutlandic Island. The Danish part of Jutland is currently divided into three regions, North Denmark Region, Central Denmark Region and Region of Southern Denmark. These three regions have an area of 29,775 km2, a population of 2,599,104. The northernmost part of Jutland is separated from the mainland by the Limfjord and this area is called the North Jutlandic Island, Vendsyssel-Thy or simply Jutland north of the Limfjord, it is only partly co-terminous with the North Jutland region. Inhabitants of Als would agree to be South Jutlanders, but not necessarily Jutlanders, the Danish Wadden Sea Islands and the German North Frisian Islands stretch along the southwest coast of Jutland in the German Bight. Jutland has historically been one of the three lands of Denmark, the two being Scania and Zealand. Before that, according to Ptolemy, Jutland or the Cimbric Chersonese was the home of Teutons, Cimbri, many Angles, Saxons and Jutes migrated from Continental Europe to Great Britain starting in c.450 AD. The Angles themselves gave their name to the new emerging kingdoms called England and this is thought by some to be related to the invasion of Europe by the Huns from Asia. Saxons and Frisii migrated to the region in the part of the Christian era. Old Saxony was later on referred to as Holstein, during the First World War, the Battle of Jutland in the North Sea west of Jutland was one of the largest naval battles in history. In this pitched battle, the British Royal Navy engaged the Imperial German Navy, the British fleet sustained greater losses, but remained in control of the North Sea, so in strategic terms, most historians regard Jutland either as a British victory or as indecisive. The distinctive Jutish dialects differ substantially from standard Danish, especially West Jutlandic, dialect usage, although in decline, is better preserved in Jutland than in eastern Denmark, and Jutlander speech remains a stereotype among many Copenhageners and eastern Danes. Administratively, Danish Jutland comprises three of Denmarks five regions, namely the Region Nordjylland, Region Midtjylland and the half of Region of Southern Denmark

Scandinavian Peninsula
–
The name of the peninsula is derived from the term Scandinavia, the cultural region of Denmark, Norway and Sweden. The derived term Scandinavian also refers to the Germanic peoples who speak North Germanic languages, the Scandinavian Peninsula is the largest peninsula of Europe, larger than the Balkan, the Iberian and the Italian peninsulas. Arguably the largest peninsula in Europe, the Scandinavian Peninsula is approximately 1,850 kilometres long with a width varying approximately from 370 to 805 kilometres, the Scandinavian mountain range generally defines the border between Norway and Sweden. These mountains also have the largest glacier on the mainland of Europe, about one quarter of the Scandinavian Peninsula lies north of the Arctic Circle, its northernmost point being at Cape Nordkyn, Norway. The region is rich in timber, iron and copper with the best farmland in southern Sweden, large petroleum and natural-gas deposits have been found off Norways coast in the North Sea and the Atlantic Ocean. Much of the population of the Scandinavian Peninsula is naturally concentrated in its southern part, the largest cities of the peninsula are Stockholm, Sweden, Oslo, Norway, Gothenburg, Sweden, Malmö, Sweden and Bergen, Norway, in that order. The Scandinavian Peninsula occupies part of the Baltic Shield, a stable and large crust segment formed of very old, crystalline metamorphic rocks. Most of the soil covering this substrate was scraped by glaciers during the Ice Ages of antiquity, especially in northern Scandinavia, as a consequence of this scouring, the elevation of the land and the cool-to-cold climate, a relatively small percentage of its land is arable. The glaciation during the Ice Ages also deepened many of the river valleys, in the southern part of the peninsula, the glaciers deposited vast numbers of terminal moraines, configuring a very chaotic landscape. These terminal moraines covered all of what is now Denmark, when the ice sheet disappeared, the shield rose again, a tendency that continues to this day at a rate of about one metre per century. Conversely, the part has tended to sink to compensate, causing flooding of the Low Countries. The crystalline substrate of the land and absence of soil in places have exposed mineral deposits of metal ores, such as those of iron, copper, nickel, zinc, silver. The very most valuable of these have been the deposits of ore in northwestern Sweden. This railway is in a region of Norway and Sweden that otherwise does not have any railways because of the rugged terrain, mountains. The first recorded presence in the southern area of the peninsula. As the ice sheets from the glaciation retreated, the climate allowed a tundra biome that attracted reindeer hunters, the climate warmed up gradually, favouring the growth of evergreen trees first and then deciduous forest which brought animals like aurochs. Groups of hunter-fisher-gatherers started to inhabit the area from the Mesolithic, in the earliest recorded periods they occupied the arctic and subarctic regions as well as the central part of the peninsula as far south as Dalarna, Sweden. They speak the Sami language, a language of the Uralic family which is related to Finnish

Fennoscandia
–
Fennoscandia, Fenno-Scandinavia, or the Fennoscandian Peninsula, is the geographical peninsula of the Nordic region comprising the Scandinavian Peninsula, Finland, Karelia, and the Kola Peninsula. It encompasses Finland, Norway and Sweden, as well as Murmansk Oblast, much of the Republic of Karelia and its name comes from the Latin words Fennia and Scandia. The term was first used by the Finnish geologist Wilhelm Ramsay in 1898, geologically, the area is distinct because its bedrock is Archaean granite and gneiss with very little limestone, in contrast to adjacent areas in Europe

Temperate broadleaf and mixed forest
–
Temperate broadleaf and mixed forest is a temperate climate terrestrial biome, with broadleaf tree ecoregions, and with conifer and broadleaf tree mixed coniferous forest ecoregions. The term Temperate broadleaf and mixed forest is used by the World Wildlife Fund in global biogeography as one of the biome designations under which to organize ecoregions, the typical structure of these forests includes four layers. The uppermost layer is the canopy composed of mature trees ranging from 30 to 61 m high. Below the canopy is the three-layered, shade-tolerant understory that is roughly 9 to 15 m shorter than the canopy, the top layer of the understory is the sub-canopy composed of smaller mature trees, saplings, and suppressed juvenile canopy layer trees awaiting an opening in the canopy. Below the sub-canopy is the layer, composed of low growing woody plants. Typically the lowest growing layer is the cover or herbaceous layer. In the Northern hemisphere, characteristic dominant broadleaf trees in this biome include oaks, beeches, maples, the term mixed forest comes from the inclusion of coniferous trees as a canopy component of some of these forests. Typical coniferous trees include, Pines, firs, and spruces, in some areas of this biome the conifers may be a more important canopy species than the broadleaf species. In the Southern hemisphere, endemic genera such as Nothofagus and Eucalyptus occupy this biome, Temperate broadleaf and mixed forests occur in areas with distinct warm and cool season, which give it a moderate annual average temperature —3 to 15.6 °C. These forests occur in warm and rainy climates, sometimes also with a distinct dry season. A dry season occurs in the winter in East Asia and in summer on the wet fringe of the Mediterranean climate zones. Other areas, as in the central and upper eastern United States and southeastern Canada, have an even distribution of rainfall, annual rainfall is typically over 600 mm

Biome
–
A biome /ˈbaɪoʊm/ is a community of plants and animals that have common characteristics for the environment they exist in, and can be found over a range of continents. Spanning continents, biomes are distinct biological communities that have formed in response to a shared physical climate, biome is a broader term than habitat, any biome can comprise a variety of habitats. While a biome can cover large ares, a microbiome is a mix of organisms that coexist in a space as well. For example, the microbiome is the collection of bacteria, viruses. The biotas of the Earth make up the biosphere, the term was suggested in 1916 by Clements, originally as a synonym for biotic community of Möbius. In 1935, Tansley added the climatic and soil aspects to the idea, the International Biological Program projects popularized the concept of biome. However, in contexts, the term biome is used in a different manner. Both includes many biomes in fact and their boundaries must therefore be drawn arbitrarily and their characterization made according to the average conditions that predominate in them. A1978 study on North American grasslands found a positive correlation between evapotranspiration in mm/yr and above-ground net primary production in g/m2/yr. These findings help explain the categories used in Holdridge’s bioclassification scheme, Holdridge uses the four axes to define 30 so-called humidity provinces, which are clearly visible in his diagram. While this scheme largely ignores soil and sun exposure, Holdridge acknowledged that these were important and his scheme can be seen as a simplification of Holdridges, more readily accessible, but missing Holdridges greater specificity. Whittaker based his approach on theoretical assertions and empirical sampling and he was in a unique position to make such a holistic assertion because he had previously compiled a review of biome classifications. Physiognomy, the apparent characteristics, outward features, or appearance of communities or species. Biome, a grouping of terrestrial ecosystems on a continent that are similar in vegetation structure, physiognomy, features of the environment. Formation, a kind of community of plants on a given continent. Biome-type, grouping of convergent biomes or formations of different continents, whittakers distinction between biome and formation can be simplified, formation is used when applied to plant communities only, while biome is used when concerned with both plants and animals. Whittakers convention of biome-type or formation-type is simply a method to categorize similar communities. Whittaker considered four main ecoclines in the terrestrial realm, changes in physiognomic complexity vary with how favorable of an environment exists

Steppe
–
In South Africa they are referred to as Veld. The prairie is an example of a steppe, though it is not usually called such and it may be semi-desert, or covered with grass or shrubs or both, depending on the season and latitude. The term is used to denote the climate encountered in regions too dry to support a forest. The soil is typically of chernozem type, steppes are usually characterized by a semi-arid and continental climate. Extremes can be recorded in the summer of up to 45 °C and in winter, besides this huge difference between summer and winter, the differences between day and night are also very great. In the highlands of Mongolia,30 °C can be reached during the day with sub-zero °C readings at night, the mid-latitude steppes can be summarized by hot summers and cold winters, averaging 250–510 mm of precipitation per year. Precipitation level alone is not what defines a steppe climate, potential evapotranspiration must also be taken into account, the Eurasian Grass-Steppe of the temperate grasslands, savannas, and shrublands had a role in the spread of the horse, the wheel, and the Indo-European languages. The Indo-European expansion and diverse invasions of horse archer civilizations of the steppe eventually led to, the Pannonian Plain is another steppe region in eastern Europe, primarily Hungary. Another large steppe area is located in the central United States, western Canada, the shortgrass prairie steppe is the westernmost part of the Great Plains region. The Channeled Scablands in Southern British Columbia and Washington State is an example of a region in North America outside of the Great Plains. In South America, cold steppe can be found in Patagonia, relatively small steppe areas can be found in the interior of the South Island of New Zealand. In Asia, a subtropical steppe can be found in semi-arid lands that fringe the Thar Desert of the Indian subcontinent, in Australia, subtropical steppe can be found in a belt surrounding the most severe deserts of the continent and around the Musgrave Ranges.

Eurasian Steppe
–
The Eurasian Steppe, also called the Great Steppe or the steppes, is the vast steppe ecoregion of Eurasia in the temperate grasslands, savannas, and shrublands biome. It stretches from Romania, Moldova through Ukraine, Russia, Kazakhstan, Xinjiang and Mongolia to Manchuria, with one major exclave located mostly in Hungary, the Eurasian Steppe extends thousands of miles from near the mouth of the Danube River almost to the Pacific Ocean. It is bounded on the north by the forests of Russia and Siberia, there is no clear southern boundary although the land becomes increasingly dry as one moves south. The steppe narrows at two points, dividing it into three major parts, the Western Steppe begins near the mouth of the Danube and extends northeast almost to Kazan and then southeast to the southern tip of the Ural Mountains. Its northern edge was a band of forest-steppe which has now been obliterated by the conversion of the whole area to agricultural land. In the southeast the Black Sea-Caspian Steppe extends between the Black Sea and Caspian Sea to the Caucasus Mountains, in the west, the Great Hungarian Plain is an island of steppe separated from the main steppe by the mountains of Transylvania. On the north shore of the Black Sea, the Crimean Peninsula has some interior steppe, the Ural Mountains extend south to a point about 650 km northeast of the Caspian Sea. This is not a barrier to movement, but the area near the Caspian is quite dry. The Central Steppe or Kazakh Steppe extends from the Urals to Dzungaria, in the southeast is the densely populated Fergana Valley and west of it the great oasis cities of Tashkent, Samarkand and Bukhara along the Zarafshan River. The southern area has a history, while in the north. On the east side of the former Sino-Soviet border mountains extend north almost to the forest zone with only limited grassland in Dzungaria, Xinjiang is the northwestern province of China. The east-west Tien Shan Mountains divide it into Dzungaria in the north, Dzungaria is bounded by the Tarbagatai Mountains on the west and the Mongolian Altai Mountains on the east, neither of which is a significant barrier. Dzungaria has good grassland around the edges and a central desert and it often behaved as a westward extension of Mongolia and connected Mongolia to the Kazakh steppe. To the north of Dzungaria are mountains and the Siberian forest, to the south and west of Dzungaria, and separated from it by the Tianshan Mountains, is an area about twice the size of Dzungaria, the oval Tarim Basin. The Tarim Basin formed an island of civilization in the center of the steppe. The Northern Silk Road went along the north and south sides of the Tarim Basin, at the west end of the basin the Pamir Mountains connect the Tien Shan Mountains to the Himalaya Mountains. To the south, the Kunlun Mountains separate the Tarim Basin from the thinly peopled Tibetan Plateau, the Mongol Steppe includes both Mongolia and the Chinese province of Inner Mongolia. The two are separated by a dry area marked by the Gobi Desert

Pannonian Basin
–
The Pannonian Basin or Carpathian Basin is a large basin in Central Europe. It is a subsystem of the Alps-Himalaya system. Most of the consists of the Great Hungarian Plain and the Little Hungarian Plain. The Pannonian Basin lies in the part of Central Europe. It forms a discrete unit set in the European landscape, surrounded by imposing geographic boundaries - the Carpathian Mountains, the Alps, the Dinarides. The Rivers Danube and Tisza divide the basin roughly in half and it extends roughly between Vienna in the northwest, Zagreb in the southwest, Belgrade in the southeast and Satu Mare in the northeast. The name Pannonian comes from Pannonia, a province of the Roman Empire, in English, the terms Pannonian Basin and Carpathian Basin are used synonymously. The name Pannonian is taken from that of Pannonia, a province of the Roman Empire, the historical province overlapped but was not coterminous with the geographical plain or basin. Pannonia Inferior covered much of the half of the basin. Pannonia Superior included the western fringe of the basin as well as part of the Eastern Alps, the southern fringe of the basin was in Dalmatia and Moesia. The eastern half of the basin was not conquered by the Romans, likewise, the parts north of the Danube were not in the empire, they were considered part of Germania, inhabited by the Quadi. The term Pannonian Plain refers to the parts of the Pannonian Basin as well as those of some adjoining regions like Lower Austria, Moravia, Bosnia. The lands adjoining the plain proper are also called peri-Pannonian. In Hungarian geographical literature various subdivisions of the Carpathian Mountains are also considered parts of the Carpathian Basin on the basis of traditional geopolitical divisions, julius Pokorny derived the name Pannonia from Illyrian, from the Proto-Indo-European root *pen-, swamp, water, wet. For its early settlers, the plain offered few sources of metals or stone, thus when archaeologists come upon objects of obsidian or chert, copper or gold, they have almost unparalleled opportunities to interpret ancient pathways of trade. The Pannonian plain is divided into two parts along the Transdanubian Mountains, the northwestern part is called Western Pannonian plain and the southeastern part Eastern Pannonian plain. The plain was named after the Pannon named Medes, various different peoples inhabited the plain during its history. In the first century BC, the parts of the plain belonged to the Dacian state
23.
Po Valley
–
The Po Valley, Po Plain, Plain of the Po, or Padan Plain is a major geographical feature of Italy. The flatlands of Veneto and Friuli are often considered apart since they do not drain into the Po, the plain is the surface of an in-filled system of ancient canyons extending from the Apennines in the south to the Alps in the north, including the northern Adriatic. Geo-political definitions of the valley depend on the defining authority, the Po Basin Water Board, authorized in 1989 by Law no. The law defines the Po basin as the territory from which rainwater or snow and glacier melt flows on the surface, the valley is crossed by a number of affluents running down from the Alps in the north and from the Apennines in the south. The Pos major affluents include the Tanaro, Scrivia, Trebbia, Panaro and Secchia in the south, Dora Riparia, Dora Baltea, Sesia, Ticino, Lambro, Adda, Oglio and Mincio in the north. Since the Messinian the system has been filling with sediment mainly from the older Apennines, the shoreline of the Adriatic depends on a balance between the sedimentation rate and isostatic factors. Until about 1950 the Po delta was prograding into the Adriatic, where the land surface now dips below sea level the river must run at a relative elevation between dikes. The Po Valley is often regarded as a syncline, or dip in the crust due to compression at the edges. Regardless of whether this concept accurately describes its geology, the valley is manifestly a sediment-filled trough, or virtual syncline, the upper areas of the Po valley take local names which reflect in their meanings their being modestly suited for farming. It varies from a few kilometres to as much as 50 km wide, the fontanili line is the outcrop, or intersection, of the anticlines water table with the surface at the edge of the bassa. The rock above the line is porous, surface water in the intermittent streams of the mountains tends to disappear below ground only to spring out again in the spring zone. The spring zone is called the middle valley. Surface runoff water is not of value to the valleys dense population for drinking and other immediate uses, being unreliable, often destructive and heavily polluted by sewage. Its main anthropic value is for power, irrigation and industrial transport. The cost of purifying it for consumption makes that process less feasible. The fresh drinking water comes from hundreds of thousands of wells concentrated especially in the fontanili zone, the older and smaller cities deriving from ancient times are still located there. The Po Valley has a subtropical climate. The conformation of the plain, surrounded by the Alps and the Apennines, the climate of the Po Valley becomes increasingly warmer and more humid farther south and east
24.
Po (river)
–
The Po is a river that flows eastward across northern Italy. The Po flows either 652 km or 682 km – considering the length of the Maira, the headwaters of the Po are a spring seeping from a stony hillside at Pian del Re, a flat place at the head of the Val Po under the northwest face of Monviso. The Po ends at a delta projecting into the Adriatic Sea near Venice and it has a drainage area of 74,000 km² in all,70,000 in Italy, of which 41,000 is in montane environments and 29,000 on the plain. The Po is the longest river in Italy, at its widest point its width is 503 m, the Po extends along the 45th parallel north. The river flows through many important Italian cities, including Turin, Piacenza and it is connected to Milan through a net of channels called navigli, which Leonardo da Vinci helped design. Near the end of its course, it creates a delta at the southern part of which is Comacchio. The Po valley was the territory of the Roman Cisalpine Gaul, divided into Cispadane Gaul, the Po begins in the Alps, and is in Italy, and flows eastward. The river is subject to heavy flooding, consequently, over half its length is controlled with argini, or dikes. The slope of the valley decreases from 0. 35% in the west to 0. 14% in the east and it is characterized by its large discharge. The vast valley around the Po is called the Po Basin or Po Valley, in 2002, more than 16 million people lived there, at the time nearly ⅓ of the population of Italy. The two main uses of the valley are for industry and for agriculture, both major uses. The industrial centres, such as Turin and Milan, are located on higher terrain and they rely for power on the numerous hydroelectric stations in or on the flanks of the Alps, and on the coal/oil power stations which use the water of the Po basin as coolant. Drainage from the north is mediated through several large, scenic lakes, the streams are now controlled by so many dams as to slow the rivers sedimentation rate, causing geologic problems. The main products of the farms around the river are cereals including – unusually for Europe – rice, the latter method is the chief consumer of surface water, while industrial and human consumption use underground water. The Po Delta wetlands have been protected by the institution of two parks in the regions in which it is situated, Veneto and Emilia-Romagna. The Po Delta Regional Park in Emilia-Romagna, the largest, consists of four parcels of land on the bank of the Po. Executive authority resides in an assembly of the presidents of the provinces, the mayors of the comuni and they employ a Technical-Scientific Committee and a Park Council to carry out directives. In 1999 the park was designated a World Heritage Site by UNESCO and was added to Ferrara, City of the Renaissance, the 53,653 ha of the park contain wetlands, forest, dunes and salt pans

North European Plain
–
The North European Plain, or Middle European Plain is a geomorphological region in Europe, mostly in Poland, Denmark, Germany, Belgium, the Netherlands, and a small part of northern France. It consists of the low plains between the Hercynian Europe to the south and coastlines of the North Sea and the Baltic Sea to the north and these two seas are separated by the Jutland Peninsula. The North European Plain is connected to East European Plain, together forming the European Plain, the Northern European Plains main use is commercial farming, with little natural vegetation remaining. Elevations vary between 0 and 200 m, while mostly used as farmland, the region also contains bogs, heath and lakes. On the North Sea coast one finds the Wadden Sea, a tidal area. On the Baltic Sea coast one finds the Szczecin Lagoon, the Vistula Lagoon and the Curonian Lagoon, the North European Plain covers the territories of Belgium, the Netherlands, Germany, Denmark, and Poland, it touches the Czech Republic and southwestern part of Sweden as well. Parts of eastern England can also be considered part of the same plain, the Northern European Plains are located also under the Baltic Sea. Major river-drainage basins include, from west to east, the Rhine, Ems, Weser, Elbe, Oder, the bases of these rivers are heavy with thin soil, making it hard for the farming industry to thrive in the located rivers. Historically, especially in the Middle Ages and Early modern period, the western section has been known as the Low Countries
26.
East European Plain
–
The East European Plain is a vast interior plain extending east of the North European Plain, and comprising several plateaus stretching roughly from 25 degrees longitude eastward. It includes the westernmost Volhynian-Podolian Upland, than the Central Russian Upland, the plain includes also a series of major river basins such as the Dnepr Basin, the Oka-Don Lowland, and the Volga Basin. Along the southernmost point of the East European Plain are the Caucasus, together with the North European Plain covering much of central Poland, Estonia, Latvia and Lithuania, it constitutes the European Plain, the mountain-free part of the European landscape. The East European Plain covers all or most of the Baltic states, Belarus, Ukraine, Moldova, Romania, the plain spans approximately 4,000,000 km2 and averages about 170 m in elevation. The highest point of the plain, located in the Valdai Hills is 346.9 metres, west, Baltic Sea, Oder and Lusatian Neisse, Sudetenland, Carpathians. South, Balkan Mountains, Crimean Mountains, Caucasus, black Sea, Sea of Azov and The Caspian Sea, Ustyurt Plateau. East, Ural Mountains and Turan Depression, North, White Sea, Barents Sea, Kara Sea, Scandinavian Mountains

Geomorphology
–
Geomorphology is the scientific study of the origin and evolution of topographic and bathymetric features created by physical, chemical or biological processes operating at or near the Earths surface. Geomorphologists work within disciplines such as geography, geology, geodesy, engineering geology, archaeology. This broad base of interests contributes to many styles and interests within the field. Earths surface is modified by a combination of processes that sculpt landscapes, and geologic processes that cause tectonic uplift and subsidence. Many of these factors are strongly mediated by climate, the broad-scale topographies of the Earth illustrate this intersection of surface and subsurface action. Mountain belts are uplifted due to geologic processes, denudation of these high uplifted regions produces sediment that is transported and deposited elsewhere within the landscape or off the coast. On progressively smaller scales, similar ideas apply, where individual landforms evolve in response to the balance of additive processes, often, these processes directly affect each other, ice sheets, water, and sediment are all loads that change topography through flexural isostasy. Topography can modify the climate, for example through orographic precipitation. Many geomorphologists are particularly interested in the potential for feedbacks between climate and tectonics, mediated by geomorphic processes, in addition to these broad-scale questions, geomorphologists address issues that are more specific and/or more local. Fluvial geomorphologists focus on rivers, how they transport sediment, migrate across the landscape, cut into bedrock, respond to environmental and tectonic changes, and interact with humans. Soils geomorphologists investigate soil profiles and chemistry to learn about the history of a landscape and understand how climate, biota. Other geomorphologists study how hillslopes form and change, still others investigate the relationships between ecology and geomorphology. Because geomorphology is defined to comprise everything related to the surface of the Earth and its modification, geomorphologists use a wide range of techniques in their work. These may include fieldwork and field data collection, the interpretation of remotely sensed data, geochemical analyses, geomorphologists may rely on geochronology, using dating methods to measure the rate of changes to the surface. Practical applications of geomorphology include hazard assessment, river control and stream restoration, planetary geomorphology studies landforms on other terrestrial planets such as Mars. Indications of effects of wind, fluvial, glacial, mass wasting, meteor impact, tectonics and this effort not only helps better understand the geologic and atmospheric history of those planets but also extends geomorphological study of the Earth. Planetary geomorphologists often use Earth analogues to aid in their study of surfaces of other planets, other than some notable exceptions in antiquity, geomorphology is a relatively young science, growing along with interest in other aspects of the earth sciences in the mid-19th century. This section provides a brief outline of some of the major figures

Russia
–
Russia, also officially the Russian Federation, is a country in Eurasia. The European western part of the country is more populated and urbanised than the eastern. Russias capital Moscow is one of the largest cities in the world, other urban centers include Saint Petersburg, Novosibirsk, Yekaterinburg, Nizhny Novgorod. Extending across the entirety of Northern Asia and much of Eastern Europe, Russia spans eleven time zones and incorporates a range of environments. It shares maritime borders with Japan by the Sea of Okhotsk, the East Slavs emerged as a recognizable group in Europe between the 3rd and 8th centuries AD. Founded and ruled by a Varangian warrior elite and their descendants, in 988 it adopted Orthodox Christianity from the Byzantine Empire, beginning the synthesis of Byzantine and Slavic cultures that defined Russian culture for the next millennium. Rus ultimately disintegrated into a number of states, most of the Rus lands were overrun by the Mongol invasion. The Soviet Union played a role in the Allied victory in World War II. The Soviet era saw some of the most significant technological achievements of the 20th century, including the worlds first human-made satellite and the launching of the first humans in space. By the end of 1990, the Soviet Union had the second largest economy, largest standing military in the world. It is governed as a federal semi-presidential republic, the Russian economy ranks as the twelfth largest by nominal GDP and sixth largest by purchasing power parity in 2015. Russias extensive mineral and energy resources are the largest such reserves in the world, making it one of the producers of oil. The country is one of the five recognized nuclear weapons states and possesses the largest stockpile of weapons of mass destruction, Russia is a great power as well as a regional power and has been characterised as a potential superpower. The name Russia is derived from Rus, a state populated mostly by the East Slavs. However, this name became more prominent in the later history, and the country typically was called by its inhabitants Русская Земля. In order to distinguish this state from other states derived from it, it is denoted as Kievan Rus by modern historiography, an old Latin version of the name Rus was Ruthenia, mostly applied to the western and southern regions of Rus that were adjacent to Catholic Europe. The current name of the country, Россия, comes from the Byzantine Greek designation of the Kievan Rus, the standard way to refer to citizens of Russia is Russians in English and rossiyane in Russian. There are two Russian words which are translated into English as Russians

European Russia
–
Russia is not proportionately populated between the smaller western portion of the country that is considered part of Europe, and the larger eastern portion that is part of Asia. European Russia contains about 77% of the population in an area comprising almost 4 million km2. This territory makes up 38% of Europe and its eastern border is defined by the Ural Mountains and in the south, it is defined by the border with Kazakhstan. This area includes Moscow and Saint Petersburg, the two largest cities in Russia, the eastern portion of Russia, mostly Siberia, is part of Asia and makes up more than 75% of the territory with 22% of the countrys population at 2.5 persons per km2. The term “European Russia” was used in the Russian Empire to refer to traditional East Slavic territories under Russian control, including what is now Belarus, administrative districts do not exactly line up with European Russia, but they are decent approximations, depending on exactly how Europe is defined. There are two trends, one to use administrative divisions north of the terminus of the Ural River. Similarly, the imaginary line if straight, could include parts of very sparsely populated Northwestern Federal District

Loire
–
The Loire is the longest river in France. With a length of 1,012 kilometres, it drains an area of 117,054 km2, or more than a fifth of Frances land area, and is the 171st longest river in the world. Its main tributaries include the rivers Nièvre, Maine and the Erdre on its bank, and the rivers Allier, Cher, Indre, Vienne. The Loire gives its name to six departments, Loire, Haute-Loire, Loire-Atlantique, Indre-et-Loire, Maine-et-Loire, the central part of the Loire Valley, located in the Centre-Val de Loire region, was added to the World Heritage Sites list of UNESCO on December 2,2000. Vineyards and chateaux are found along the banks of the river throughout this area, gallic rule ended in the valley in 56 BC when Julius Caesar conquered the adjacent provinces for Rome. Christianity was introduced into this valley from the 3rd century AD, as missionaries, in this period, settlers established vineyards and began producing wines. They were originally created as feudal strongholds, over centuries past, the name Loire comes from Latin Liger, which is itself a transcription of the native Gaulish name of the river. The Gaulish name comes from the Gaulish word liga, which means silt, sediment, deposit, alluvium, a word that gave French lie, as in sur lie, which in turn gave English lees. Liga comes from the Proto-Indo-European root *legʰ-, meaning to lie, lay as in the Welsh word Lleyg which gave many words in English, such as to lie, to lay, ledge, law, etc. At a certain point during the history of uplift in the Paris Basin. The former bed of the Loire séquanaise is occupied by the Loing, the Loire Valley has been inhabited since the Middle Palaeolithic period from 40–90 ka. Neanderthal man used stone tools to fashion boats out of tree trunks, modern man inhabited the Loire valley around 30 ka. By around 5000 to 4000 BC, they began clearing forests along the edges and cultivating the lands. They built megaliths to worship the dead, especially from around 3500 BC, the Gauls arrived in the valley between 1500 and 500 BC, and the Carnutes settled in Cenabum in what is now Orléans and built a bridge over the river. By 600 BC the Loire had already become an important trading route between the Celts and the Greeks. A key transportation route, it served as one of the highways of France for over 2000 years. The Phoenicians and Greeks had used pack horses to transport goods from Lyon to the Loire to get from the Mediterranean basin to the Atlantic coast, during the Roman period, they successfully subdued the Gauls in 52 BC and began developing Cenabum, which they named Aurelianis. They also began building the city of Caesarodunum, now Tours, the Romans used the Loire as far as Roanne, around 150 km downriver from the source

Rhine
–
The largest city on the river Rhine is Cologne, Germany, with a population of more than 1,050,000 people. It is the second-longest river in Central and Western Europe, at about 1,230 km, with an average discharge of about 2,900 m3/s. The Rhine and the Danube formed most of the inland frontier of the Roman Empire and, since those days. The many castles and fortifications along the Rhine testify to its importance as a waterway in the Holy Roman Empire, in the modern era, it has become a symbol of German nationalism. The variant of the name of the Rhine in modern languages are all derived from the Gaulish name Rēnos, spanish is with French in adopting the Germanic vocalism Rin-, while Italian, Occitan and Portuguese retain the Latin Ren-. The Gaulish name Rēnos belongs to a class of river names built from the PIE root *rei- to move, flow, run, the grammatical gender of the Celtic name is masculine, and the name remains masculine in German, Dutch and French. The Old English river name was variously inflected as masculine or feminine, the length of the Rhine is conventionally measured in Rhine-kilometers, a scale introduced in 1939 which runs from the Old Rhine Bridge at Constance to Hoek van Holland. The river length is shortened from the rivers natural course due to a number of canalisation projects completed in the 19th and 20th century. The total length of the Rhine, to the inclusion of Lake Constance and its course is conventionally divided as follows, The Rhine carries its name without distinctive accessories only from the confluence of the Vorderrhein and Hinterrhein near Tamins-Reichenau. Above this point is the catchment of the headwaters of the Rhine. It belongs almost exclusively to the Swiss Canton of Graubünden, ranging from Gotthard Massif in the west via one valley lying in Ticino, traditionally, Lake Toma near the Oberalp Pass in the Gotthard region is seen as the source of the Vorderrhein and the Rhine as a whole. The Hinterrhein rises in the Rheinwald valley below Mount Rheinwaldhorn, the Vorderrhein, or Anterior Rhine, springs from Lai da Tuma, near the Oberalp Pass and passes the impressive Ruinaulta formed by the largest visible rock slide in the alps, the Flims Rockslide. A multiday trekking route is signposted along the young Rhine called Senda Sursilvana, the Hinterrhein/Rein Posteriur, or Posterior Rhine, starts from the Paradies Glacier, near the Rheinwaldhorn. One of its tributaries, the Reno di Lei, drains the Valle di Lei on politically Italian territory, after three main valleys separated by the two gorges, Roflaschlucht and Viamala, it reaches Reichenau. The Vorderrhein arises from numerous source streams in the upper Surselva, one source is Lai da Tuma with the Rein da Tuma, which is usually indicated as source of the Rhine, flowing through it. Into it flow tributaries from the south, some longer, some equal in length, such as the Reno di Medel, the Rein da Maighels, and the Rein da Curnera. The Cadlimo Valley in the Canton of Ticino is drained by the Reno di Medel, all streams in the source area are partially, sometimes completely, captured and sent to storage reservoirs for the local hydro-electric power plants. In its lower course the Vorderrhein flows through a gorge named Ruinaulta through the Flims Rockslide, the whole stretch of the Vorderrhein to the Rhine confluence near Reichenau-Tamins is accompanied by a long-distance hiking trail called Senda Sursilvana

Vistula
–
The Vistula is the longest and largest river in Poland, at 1,047 kilometres in length. The drainage basin area of the Vistula is 194,424 km2, the remainder is in Belarus, Ukraine and Slovakia. The Vistula rises at Barania Góra in the south of Poland,1,220 meters above sea level in the Silesian Beskids, where it begins with the White Little Vistula and the Black Little Vistula. It empties into the Vistula Lagoon or directly into the Gdańsk Bay of the Baltic Sea with a delta, the name was first recorded by Pomponius Mela in AD40 and by Pliny in AD77 in his Natural History. Mela names the river Vistula, Pliny uses Vistla, the root of the name Vistula is Indo-European *u̯eis- to ooze, flow slowly and is found in many European rivernames. The diminutive endings -ila, -ula, were used in many Indo-European languages, in writing about the Vistula River and its peoples, Ptolemy uses the Greek spelling Ouistoula. Other ancient sources spell it Istula, ammianus Marcellinus refers to the Bisula, note the absence of the -t-. Jordanes uses Viscla, while the Anglo-Saxon poem Widsith refers to it as the Wistla, the Vistula river basin covers 194,424 square kilometres, its average altitude rising to 270 metres above sea level. In addition, the majority of its basin is located at heights of 100 to 200 m above sea level. The highest point of the basin lies at 2,655 metres. The asymmetry of the basin is 73–27%. The most recent glaciation of the Pleistocene epoch, which ended around 10,000 BC, is called the Vistulian glaciation or Weichselian glaciation in regard to north-central Europe. The river forms a delta called the Żuławy Wiślane around the town of Biała Góra near Sztum, about 50 km from the mouth. In the city of Gdańsk the Head of the Leniwka branch separates again into the Szkarpawa branch, the so-called Dead Wisła divides again into the Przegalinie branch flowing into Gdańsk Bay. Until the 14th century the Vistula was divided into an eastern branch, the Elbląg Vistula, and the smaller western branch. Since 1371 the Vistula of Gdańsk is the main artery. After the flood in 1840 an additional branch formed called the Śmiała Wisła, in 1890 through 1895, additional waterworks were carried out up the Świbna. The history of the River Vistula and her valley spans over 2 million years, the river is connected to the geological period called the Quaternary, in which distinct cooling of the climate took place

Northern Dvina River
–
The Northern Dvina is a river in northern Russia flowing through the Vologda Oblast and Arkhangelsk Oblast into the Dvina Bay of the White Sea. Along with the Pechora River to the east, it drains most of Northwest Russia into the Arctic Ocean and it should not be confused with Western Dvina. The principal tributaries of the Northern Dvina are the Vychegda, the Vaga, according to the Max Vasmers Etymological Dictionary, the name of the river has been taken from the Western Dvina River. The toponym Dvina does not stem from a Uralic language, however, possibly it is an Indo-European word which used to mean river or stream. In the Komi language, the river is called Вы́нва / Výnva from vyn power, the length of the Northern Dvina is 744 kilometres. Together with its tributary, the Sukhona, it is 1,302 kilometres long – about as long as the Rhine River in central. The area of its basin is 357,052 square kilometres – about the size of the state of Montana in the United States. The Northern Dvina basin is roughly T-shaped, the 558 kilometres -long Sukhona River flows east and joins the basin of the west-flowing Vychegda River. The combined river flows northwest into the White Sea, which it joins near the city of Archangelsk, looking more closely, the Sukhona flows east and meets the north-flowing Yug River at Veliky Ustyug. The combined stream, now called the Northern Dvina, flows north about 60 km and receives the west-flowing Vychegda at Kotlas, the Sukhona-Vychegda was an important east–west transportation route while the Northern Dvina-Yug was a north–south route. The upper Sukhona is now connected by the Northern Dvina Canal to the Volga–Baltic Waterway, the Sukhona River flows east, eventually north-east, joins the north-flowing Yug River at Veliky Ustyug and acquires the name Northern Dvina. The P157 highway connects Kostroma with Kotlas via Nikolsk and Veliky Ustyug, North of Veliky Ustyg, the highway runs on the left bank of the Northern Dvina. Shortly downstream from the confluence, the Northern Dvina is crossed by the railway connecting Konosha with Kotlas, the Northern Dvina turns northwest and receives a number of smaller rivers such as the Uftyuga and the Nizhnyaya Toyma, both from the northeast. Near the urban settlement of Bereznik, the Vaga River comes in from the south, at this point, the M8 highway which runs from Moscow through Vologda to Arkhangelsk, also enters the region. The Yomtsa or Yemtsa River join from the southeast, with the P1 highway running parallel, the Pinega River, formerly an important river route, joins from the east. Near the mouth of the Pinega, the splits into several channels. The branches rejoin and pass the modern logging town of Novodvinsk, downstream from Novodvinsk, the 900 square kilometres delta begins. In the upstream part of the delta, the port of Arkhangelsk is located

Daugava
–
The River Daugava or Western Dvina is a river rising in the Valdai Hills, Russia, flowing through Russia, Belarus, and Latvia and into the Gulf of Riga. The total length of the river is 1,020 km,325 km in Russia,338 km in Belarus, within Latvia it flows through Latgale, Zemgale, Vidzeme and Riga, before flowing into the Gulf of Riga. The total catchment area of the river is 87,900 km2,33,150 km2 of which are within Belarus. According to the Max Vasmers Etymological Dictionary, the toponym Dvina clearly cannot stem from a Uralic language, the river began experiencing environmental deterioration in the era of Soviet collective agriculture and a wave of hydroelectric power projects. Ruba, Vitebsk, Beshankovichy, Polotsk with Boris stones strewn in the vicinity, Navapolatsk, Dzisna, Verkhnedvinsk, krāslava, Daugavpils, Līvāni, Jēkabpils, Pļaviņas, Aizkraukle, Jaunjelgava, Lielvārde, Kegums, Ogre, Ikšķile, Salaspils and Riga. Beginning around the sixth century AD, Viking explorers crossed the Baltic Sea and entered the Daugava River, in medieval times the Daugava was an important navigation trading route for transport of furs from the north and Byzantine silver. In Belarus, water pollution of the Daugava is considered severe, with the chief sources being treated wastewater, fish-farming. Daugava River photos at flickr Richard C, francis W.

Volga River
–
The Volga is the longest river in Europe. It is also Europes largest river in terms of discharge and watershed, the river flows through central Russia and into the Caspian Sea, and is widely regarded as the national river of Russia. Eleven of the twenty largest cities of Russia, including the capital, some of the largest reservoirs in the world can be found along the Volga. The river has a meaning in Russian culture and is often referred to as Волга-матушка Volga-Matushka in Russian literature and folklore. The Slavic name is a translation of earlier Scythian Rā Volga, literally wetness, cognate with Avestan Raŋhā mythical stream and Sanskrit rasā́- dew, liquid, juice. The Scythian name survives in modern Mordvin Rav Volga, the Turkic peoples living along the river formerly referred to it as Itil or Atil big river. In modern Turkic languages, the Volga is known as İdel in Tatar, Атăл in Chuvash, Idhel in Bashkir, Edil in Kazakh, the Turkic peoples associated the Itils origin with the Kama. Thus, a tributary to the Kama was named the Aq Itil White Itil which unites with the Kara Itil Black Itil at the modern city of Ufa. The name Indyl is used in Adyge language, among Asians, the river was known by its other Turkic name Sarı-su yellow water, but the Oirats also used their own name, Ijil mörön or adaptation river. Presently the Mari, another Uralic group, call the river Jul, formerly, they called the river Volgydo, a borrowing from Old Russian. The Volga is the longest river in Europe and it belongs to the closed basin of the Caspian Sea, being the longest river to flow into a closed basin. From there it turns south, flows past Ulyanovsk, Tolyatti, Samara, Saratov and Volgograd, at its most strategic point, it bends toward the Don. Volgograd, formerly Stalingrad, is located there, the Volga has many tributaries, most importantly the rivers Kama, the Oka, the Vetluga, and the Sura. The Volga and its tributaries form the Volga river system, which flows through an area of about 1,350,000 square kilometres in the most heavily populated part of Russia. The Volga Delta has a length of about 160 kilometres and includes as many as 500 channels, the largest estuary in Europe, it is the only place in Russia where pelicans, flamingos, and lotuses may be found. The Volga freezes for most of its length for three each year. The Volga drains most of Western Russia and its many large reservoirs provide irrigation and hydroelectric power. The Moscow Canal, the Volga–Don Canal, and the Volga–Baltic Waterway form navigable waterways connecting Moscow to the White Sea, the Baltic Sea, the Caspian Sea, the Sea of Azov, high levels of chemical pollution have adversely affected the river and its habitats

Don River (Russia)
–
The Don is one of the major rivers of Russia and the 5th longest river in Europe. The Don basin is between the Dnieper basin to the west, the Volga basin to the east, and the Oka basin to the north. The Don rises in the town of Novomoskovsk 60 kilometres southeast of Tula, from its source, the river first flows southeast to Voronezh, then southwest to its mouth. The main city on the river is Rostov on Don and its main tributary is the Seversky Donets. In antiquity, the river was viewed as the border between Europe and Asia by some ancient Greek geographers, during the times of the old Scythians it was known in Greek as the Tanaïs and has been a major trading route ever since. Tanais appears in ancient Greek sources as both the name of the river and of a city on it, situated in the Maeotian marshes, pliny gives the Scythian name of the Tanais as Silys. According to Plutarch, the Don River was also home to the legendary Amazons of Greek mythology, the area around the estuary is speculated to be the source of the Black Death. While the lower Don was well known to ancient geographers, its middle, the Don Cossacks, who settled the fertile valley of the river in the 16th and 17th centuries, were named after the river. The fort of Donkov was founded by the princes of Ryazan in the late 14th century and it is shown as Donko in Mercators Atlas, Donkov was again relocated in 1618, appearing as Donkagorod in Joan Blaeus map of 1645. Both Blaeu and Mercator follow the 16th-century cartographic tradition of letting the Don originate in a great lake, Mercator still follows Giacomo Gastaldo in showing a waterway connecting this lake to Ryazan and the Oka River. In modern literature, the Don region was featured in the work And Quiet Flows the Don of Mikhail Aleksandrovich Sholokhov, at its easternmost point, the Don comes near the Volga, and the Volga-Don Canal, connecting the two rivers, is a major waterway. The water level of the Don in this area is raised by the Tsimlyansk Dam and this facility, with its dam, maintains sufficient water level both in its section of the Don and in the lowermost stretch of the Seversky Donets. This is presently the last lock on the Don, below Kochetovsky lock, the sufficient depth of the navigation waterway is maintained by dredging

Dnieper
–
It is the longest river of Ukraine and Belarus and the fourth longest river in Europe. The total length ranges between 2,145 km and 2,201 km with a basin of 504,000 square kilometres. The river is noted for its dams and hydroelectric stations, the Dnieper is an important navigable waterway for the economy of Ukraine and is connected via the Dnieper–Bug Canal to other waterways in Europe. In antiquity, the river was known to the Greeks as the Borysthenes and was part of the Amber Road, Arheimar, a capital of the Goths, was located on the Dnieper, according to the Hervarar saga. The name Dnieper is derived from Sarmatian Dānu apara the river on the far side, according to V. Abaev the name Dnieper derives from Scythian Dānu apr deep river, while the name Dniester is combination of Scythian Dānu and Thracian Ister, the old name of Dniester. In the three countries through which it flows it has essentially the name, albeit pronounced differently, Russian, Днепр, Belarusian, Дняпро or Днепр, Ukrainian. The late Greek and Roman authors called it Δάναπρις - Danapris and Danaper respectively - and its Old East Slavic name used at the time of Kievan Rus was Slavuta or Slavutych, the Huns called it Var, and Bulgars - Buri-Chai. The name in Crimean Tatar, Özü, the total length of the river is 2,145 kilometres, of which 485 km are within Russia,700 km are within Belarus, and 1,095 km are within Ukraine. Its basin covers 504,000 square kilometres, of which 289,000 km2 are within Ukraine,118,360 km2 are within Belarus, the source of the Dnieper is the sedge bogs of the Valdai Hills in central Russia, at an elevation of 220 m. For 115 km of its length, it serves as the border between Belarus and Ukraine and its estuary, or liman, used to be defended by the strong fortress of Ochakiv. On the Dnepr River to the south of Komarin urban-type settlement, Braghin District, the Dnieper has many tributaries with 89 being rivers of 100+ km. The water resources of the Dnieper basin compose around 80% out of all Ukraine, Dnieper Rapids were part of trade route from the Varangians to the Greeks, first mentioned in the Kiev Chronicle. The route was established in the late eighth and early ninth centuries. On the Dnieper the Varangians had to portage their ships round seven rapids, after Dnieper Hydroelectric Station was built in 1932, they were inundated by Dnieper Reservoir. The river is part of the Quagga mussels native range, the mussel has been accidentally introduced around the world where it has become an invasive species. From the mouth of the Prypiat River to the Kakhovka Hydroelectric Station, there are six sets of dams and hydroelectric stations, the first constructed was the Dnieper Hydroelectric Station near Zaporizhia, built in 1927–1932 with an output of 558 MW. It was destroyed during World War II, but was rebuilt in 1948 with an output of 750 MW, the Dnieper River in different regions Major cities, over 100,000 in population, are in bold script. Cities and towns located on the Dnieper are listed in order from the source to its mouth, Arheimar

North Sea
–
The North Sea is a marginal sea of the Atlantic Ocean located between Great Britain, Scandinavia, Germany, the Netherlands, Belgium, and France. An epeiric sea on the European continental shelf, it connects to the ocean through the English Channel in the south and it is more than 970 kilometres long and 580 kilometres wide, with an area of around 570,000 square kilometres. The North Sea has long been the site of important European shipping lanes as well as a major fishery, the North Sea was the centre of the Vikings rise. Subsequently, the Hanseatic League, the Netherlands, and the British each sought to dominate the North Sea and thus the access to the markets, as Germanys only outlet to the ocean, the North Sea continued to be strategically important through both World Wars. The coast of the North Sea presents a diversity of geological and geographical features, in the north, deep fjords and sheer cliffs mark the Norwegian and Scottish coastlines, whereas in the south it consists primarily of sandy beaches and wide mudflats. Due to the population, heavy industrialization, and intense use of the sea and area surrounding it. In the southwest, beyond the Straits of Dover, the North Sea becomes the English Channel connecting to the Atlantic Ocean, in the east, it connects to the Baltic Sea via the Skagerrak and Kattegat, narrow straits that separate Denmark from Norway and Sweden respectively. In the north it is bordered by the Shetland Islands, and connects with the Norwegian Sea, the North Sea is more than 970 kilometres long and 580 kilometres wide, with an area of 570,000 square kilometres and a volume of 54,000 cubic kilometres. Around the edges of the North Sea are sizeable islands and archipelagos, including Shetland, Orkney, the North Sea receives freshwater from a number of European continental watersheds, as well as the British Isles. A large part of the European drainage basin empties into the North Sea including water from the Baltic Sea, the largest and most important rivers flowing into the North Sea are the Elbe and the Rhine – Meuse watershed. Around 185 million people live in the catchment area of the rivers discharging into the North Sea encompassing some highly industrialized areas, for the most part, the sea lies on the European continental shelf with a mean depth of 90 metres. The only exception is the Norwegian trench, which extends parallel to the Norwegian shoreline from Oslo to a north of Bergen. It is between 20 and 30 kilometres wide and has a depth of 725 metres. The Dogger Bank, a vast moraine, or accumulation of unconsolidated glacial debris and this feature has produced the finest fishing location of the North Sea. The Long Forties and the Broad Fourteens are large areas with uniform depth in fathoms. These great banks and others make the North Sea particularly hazardous to navigate, the Devils Hole lies 200 miles east of Dundee, Scotland. The feature is a series of trenches between 20 and 30 kilometres long,1 and 2 kilometres wide and up to 230 metres deep. Other areas which are less deep are Cleaver Bank, Fisher Bank, the International Hydrographic Organization defines the limits of the North Sea as follows, On the Southwest

Baltic Sea
–
The Baltic Sea is a sea of the Atlantic Ocean, enclosed by Scandinavia, Finland, the Baltic countries, and the North European Plain. It includes the Gulf of Bothnia, the Bay of Bothnia, the Gulf of Finland, the Gulf of Riga, the sea stretches from 53°N to 66°N latitude and from 10°E to 30°E longitude. The Baltic Sea is connected by waterways to the White Sea via the White Sea Canal. Traffic history Historically, the Kingdom of Denmark collected Sound Dues from ships at the border between the ocean and the land-locked Baltic Sea and they were collected in the Øresund at Kronborg castle near Helsingør, in the Great Belt at Nyborg. In the Little Belt, the site of intake was moved to Fredericia, the narrowest part of Little Belt is the Middelfart Sund near Middelfart. Oceanography Geographers widely agree that the physical border of the Baltic is a line drawn through the southern Danish islands, Drogden-Sill. The Drogden Sill is situated north of Køge Bugt and connects Dragør in the south of Copenhagen to Malmö, it is used by the Øresund Bridge, including the Drogden Tunnel. By this definition, the Danish Straits are part of the entrance, but the Bay of Mecklenburg, another usual border is the line between Falsterbo, Sweden and Stevns Klint, Denmark, as this is the southern border of Øresund. Its also the border between the shallow southern Øresund and notably deeper water, hydrography and biology Drogden Sill sets a limit to Øresund and Darss Sill, and a limit to the Belt Sea. The shallow sills are obstacles to the flow of salt water from the Kattegat into the basins around Bornholm. The Kattegat and the southwestern Baltic Sea are well oxygenated and have a rich biology, the remainder of the Sea is brackish, poor in oxygen and in species. While Tacitus called it Mare Suebicum after the Germanic people called the Suebi, the origin of the latter name is speculative. Adam of Bremen himself compared the sea with a belt, stating that it is so named because it stretches through the land as a belt and he might also have been influenced by the name of a legendary island mentioned in the Natural History of Pliny the Elder. Pliny mentions an island named Baltia with reference to accounts of Pytheas and it is possible that Pliny refers to an island named Basilia in On the Ocean by Pytheas. Baltia also might be derived from belt and mean near belt of sea, meanwhile, others have suggested that the name of the island originates from the Proto-Indo-European root *bhel meaning white, fair. This root and its meaning were retained in both Lithuanian and Latvian. On this basis, a related hypothesis holds that the name originated from this Indo-European root via a Baltic language such as Lithuanian, yet another explanation is that the name originally meant enclosed sea, bay as opposed to open sea. Some Swedish historians believe the name derives from the god Balder of Nordic mythology, in the Middle Ages the sea was known by variety of names

Gulf of Bothnia
–
The Gulf of Bothnia is the northernmost arm of the Baltic Sea. It is situated between Finlands west coast and Swedens east coast, in the south of the gulf lie the Åland Islands, between the Sea of Åland and the Archipelago Sea. The Swedish name Bottenviken was originally just Botn with botn being Old Norse for gulf or bay, the name botn was applied to the Gulf of Bothnia as Helsingjabotn in Old Norse, after Hälsingland, which at the time referred to the coastland west of the gulf. Later, botten was applied to the regions Västerbotten on the western side, the Finnish name of Österbotten, Pohjanmaa, or Pohja-land, gives a hint as to the meaning in both languages, the meaning of pohja includes both bottom and north. Pohja is the word for north, pohjoinen, with an adjectival suffix added. A second possibility is that botten follows an alternative Scandinavian connotation of furthermost, thus, the Gulf of Bothnia would be the farthest extent of the Ocean. Julius Pokorny gives the extended Proto-Indo-European root as *bhudh-mn with a variant, from which the Latin fundus. The original meaning of English north, from Proto-Indo-European *ner- under, on the other hand, by north the classical authors usually meant outermost, as the northern lands were outermost to them. The origin of the word is indeed very ancient, belonging to a period before the world discoveries by the Portuguese, until then, north was not seen as the magnetic top of the world, East being the normal orientation of a map. Also, in Saami, the directions were named according to the different parts of the typical tent used by this nomadic people. The door of the tent was traditionally pointed South, in the most sunny direction, thus the origin of the word pohja in its use as north. Deriving as well from this logic is the affinity in the Finnish language of the words eteinen, meaning entrance room/hall and etelä, according to Lönnrot, north was viewed as the bottom direction because the lowest point of the suns path is there. The gulf is 725 km long, 80–240 km wide and has a depth of 60 m. The maximum depth is 295 m, the surface area is 117,000 km². The northernmost point is situated in Töre in the Bothnian Bay and its coordinates are 65°5407 N 22°3900 E. The depth and surface area of the Gulf of Bothnia are constantly decreasing, the rise is 80 cm every hundred years. Into the gulf flow a number of rivers from both sides, consequently, a salinity gradient exists from north to south, being nearly fresh, the gulf is frozen over five months every year. The icing of the Baltic Sea begins and ends in the northern Gulf of Bothnia, for the geological history of the entire region, refer to the Baltic Sea

The White Sea is a southern inlet of the Barents Sea located on the northwest coast of Russia. It is surrounded by Karelia to the west, the Kola Peninsula to the north, the whole of the White Sea is under Russian sovereignty and considered to be part of the internal waters of Russia. Administratively, it is divided between Arkhangelsk and Murmansk Oblasts and the Republic of Karelia, the major port of Arkhangelsk is located on the White Sea. For much of Russias history this was Russias main centre of maritime trade. In the modern era it became an important Soviet naval and submarine base, the White Sea-Baltic Canal connects the White Sea with the Baltic Sea. The White Sea is one of four seas named in English after common colour terms — the others being the Black Sea, the Red Sea, the International Hydrographic Organization defines the northern limit of the White Sea as A line joining Svyatoi Nos and Cape Kanin. There are four main bays or gulfs on the White Sea and these bays connect with the funnel-shaped opening to the Barents Sea via a narrow strait called gorlo. Kandalaksha Gulf lies in the part of the White Sea, it is the deepest part of the sea. On the south, Onega Bay receives the Onega River, to the southeast, the Dvina Bay receives the Northern Dvina River at the major port of Arkhangelsk. On the east side of the gorlo, opposite the Kola peninsula, is Mezen Bay and it receives the Mezen River and the Kuloy River. Other major rivers flowing into the sea are the Vyg, Niva, Umba, Varzuga and Ponoy. The seabed of the part and Dvina Bay is covered in silt and sand, whereas the bottom of the northern part. Ice age deposits often emerge near the sea shores, northwestern coasts are tall and rocky but the slope is much weaker at the southeastern side. The White Sea contains a number of islands, but most of them are small. The main island group is the Solovetsky Islands, located almost in the middle of the sea, kiy Island in Onega Bay is significant due to a historic monastery. Velikiy Island, located close to the shore, is the largest island in the Kandalaksha Gulf, the White Sea is a water-filled depression in the block of a continental shelf known as the Baltic Shield. Its bottom is very uneven and contains the Kandalaksha Hollow in the northwest, also, the Onega Bay has many small underwater elevations. The opening and the gorlo of the sea are rather shallow, in addition, there is an underwater ridge in the northern part of the gorlo, resulting in maximum depths of 40 metres in that part

Black Sea
–
The Black Sea is a body of water between Eastern Europe and Western Asia, bounded by Bulgaria, Georgia, Romania, Russia, Turkey, and Ukraine. It is supplied by a number of rivers, such as the Danube, Dnieper, Rioni, Southern Bug. The Black Sea has an area of 436,400 km2, a depth of 2,212 m. It is constrained by the Pontic Mountains to the south and by the Caucasus Mountains to the east, the longest east-west extent is about 1,175 km. The Black Sea has a water balance, that is, a net outflow of water 300 km3 per year through the Bosphorus. Mediterranean water flows into the Black Sea as part of a two-way hydrological exchange, the Black Sea drains into the Mediterranean Sea and then the Atlantic Ocean, via the Aegean Sea and various straits. The Bosphorus Strait connects it to the Sea of Marmara, and these waters separate Eastern Europe and Western Asia. The Black Sea is also connected to the Sea of Azov by the Strait of Kerch, the water level has varied significantly. Due to these variations in the level in the basin. At certain critical water levels it is possible for connections with surrounding water bodies to become established and it is through the most active of these connective routes, the Turkish Straits, that the Black Sea joins the world ocean. When this hydrological link is not present, the Black Sea is a basin, operating independently of the global ocean system. Currently the Black Sea water level is high, thus water is being exchanged with the Mediterranean. The Turkish Straits connect the Black Sea with the Aegean Sea, and comprise the Bosphorus, the Sea of Marmara, the International Hydrographic Organization defines the limits of the Black Sea as follows, On the Southwest. The Northeastern limit of the Sea of Marmara, a line joining Cape Takil and Cape Panaghia. Strabos Geographica reports that in antiquity, the Black Sea was often just called the Sea, for the most part, Graeco-Roman tradition refers to the Black Sea as the Hospitable sea, Εὔξεινος Πόντος Eúxeinos Póntos. This is a euphemism replacing an earlier Inhospitable Sea, Πόντος Ἄξεινος Póntos Áxeinos, strabo thinks that the Black Sea was called inhospitable before Greek colonization because it was difficult to navigate, and because its shores were inhabited by savage tribes. The name was changed to hospitable after the Milesians had colonized the southern shoreline and it is also possible that the epithet Áxeinos arose by popular etymology from a Scythian word axšaina- unlit, dark, the designation Black Sea may thus date from antiquity. A map of Asia dating to 1570, entitled Asiae Nova Descriptio, from Abraham Orteliuss Theatrum Orbis Terrarum, english-language writers of the 18th century often used the name Euxine Sea to refer to the Black Sea

Sea of Azov
–
The Sea of Azov is a sea in Eastern Europe. To the south it is linked by the narrow Strait of Kerch to the Black Sea, the sea is bounded in the north by mainland Ukraine, in the east by Russia, and in the west by the Crimean Peninsula. The Don and Kuban are the rivers that flow into it. The Sea of Azov is the shallowest sea in the world, there is a constant outflow of water from the Sea of Azov to the Black Sea. The sea is affected by the inflow of numerous rivers, which bring sand, silt, and shells, which in turn form numerous bays, limans. Because of these deposits, the sea bottom is relatively smooth, also, due to the river inflow, water in the sea has low salinity and a high amount of biomass that affects the water colour. Abundant plankton results in high fish productivity. The sea shores and spits are low, they are rich in vegetation, the name likely derives from the settlement of an area around Azov, whose name comes from the Kipchak Turkish asak or azaq. A Russian folk etymology, however, instead derives it from an eponymous Cuman prince named Azum or Asuf, a formerly common spelling of the name in English was the Sea of Azoff, which is closer to the Russian pronunciation. In antiquity, the sea was known as the Maeotis Swamp from the marshlands to its northeast. It remains unclear whether it was named for the nearby Maeotians or if that name was applied broadly to various peoples who happened to live beside it. Other names included Lake Maeotis or Maeotius, the Maeotium or Maeotic Sea, the Cimmerian or Scythican Swamps, the Maeotians themselves were said by Pliny to call the sea Temarenda or Temerinda, meaning Mother of Waters. The medieval Russians knew it as the Sea of Surozh after the adjacent city now known as Sudak and it was known in Ottoman Turkish as the Balük-Denis from its high productivity. There are traces of Neolithic settlement in the now covered by the sea. In 1997, William Ryan and Walter Pitman of Columbia University published a theory that a flood through the Bosporus occurred in ancient times. Subsequent work has been both to support and to discredit this theory, and archaeologists still debate it. This has led some to associate this catastrophe with prehistoric flood myths, the Maeotian marshes around the mouth of the Tanais River were famous in antiquity, as they served as an important check on the migration of nomadic people from the Eurasian steppelands. The Maeotians themselves lived by fishing and farming, but were avid warriors able to defend themselves against invaders

Caspian Sea
–
The Caspian Sea is the largest enclosed inland body of water on Earth by area, variously classed as the worlds largest lake or a full-fledged sea. It is in a basin located between Europe and Asia. It is bounded by Kazakhstan to the northeast, Russia to the northwest, Azerbaijan to the west, Iran to the south, the Caspian Sea lies to the east of the Caucasus Mountains and to the west of the vast steppe of Central Asia. In its northern part, the Caspian Depression lies 28 to 130 m below sea level, the sea bed in the southern part reaches as low as 1023 m below sea level, which is the second lowest natural depression on earth after Lake Baikal. The ancient inhabitants of its coast perceived the Caspian Sea as an ocean, probably because of its saltiness, the sea has a surface area of 371,000 km2 and a volume of 78,200 km3. It has a salinity of approximately 1. 2%, about a third of the salinity of most seawater, the word Caspian is derived from the name of the Caspi, an ancient people who lived to the southwest of the sea in Transcaucasia. Strabo wrote that to the country of the Albanians belongs also the territory called Caspiane, which was named after the Caspian tribe, as was also the sea, but the tribe has now disappeared. Moreover, the Caspian Gates, which is the name of a region in Irans Tehran province, the Iranian city of Qazvin shares the root of its name with that of the sea. In fact, the traditional Arabic name for the sea itself is Bahr al-Qazwin, in classical antiquity among Greeks and Persians it was called the Hyrcanian Ocean. In Persian antiquity, as well as in modern Iran, it is known as the دریای خزر, Daryā-e Khazar, ancient Arabic sources refer to it as Baḥr Gīlān meaning the Gilan Sea. Turkic languages refer to the lake as Khazar Sea, in Turkmen, the name is Hazar deňizi, in Azeri, it is Xəzər dənizi, and in modern Turkish, it is Hazar denizi. An exception is Kazakh, where it is called Каспий теңізі, old Russian sources call it the Khvalyn or Khvalis Sea after the name of Khwarezmia. In modern Russian, it is called Каспи́йское мо́ре, Kaspiyskoye more, the Caspian Sea, like the Black Sea, Namak Lake, and Lake Urmia, is a remnant of the ancient Paratethys Sea. It became landlocked about 5.5 million years ago due to tectonic uplift and a fall in sea level. Due to the current inflow of water, the Caspian Sea is a freshwater lake in its northern portions, and is most saline on the Iranian shore. Currently, the salinity of the Caspian is one third that of Earths oceans. The Caspian Sea is the largest inland body of water in the world, the coastlines of the Caspian are shared by Azerbaijan, Iran, Kazakhstan, Russia, and Turkmenistan. The Caspian is divided into three distinct regions, the Northern, Middle, and Southern Caspian

Deforestation
–
Deforestation, clearance or clearing is the removal of a forest or stand of trees where the land is thereafter converted to a non-forest use. Examples of deforestation include conversion of forestland to farms, ranches, the most concentrated deforestation occurs in tropical rainforests. About 30% of Earths land surface is covered by forests, Deforestation occurs for multiple reasons, trees are cut down to be used for building or sold as fuel, while cleared land is used as pasture for livestock and plantation. The removal of trees without sufficient reforestation has resulted in damage to habitat, biodiversity loss and it has adverse impacts on biosequestration of atmospheric carbon dioxide. Deforestation has also used in war to deprive the enemy of cover for its forces. Modern examples of this were the use of Agent Orange by the British military in Malaya during the Malayan Emergency, as of 2005, net deforestation rates have ceased to increase in countries with a per capita GDP of at least US$4,600. Deforested regions typically incur significant adverse soil erosion and frequently degrade into wasteland, disregard of ascribed value, lax forest management and deficient environmental laws are some of the factors that allow deforestation to occur on a large scale. In many countries, deforestation, both naturally occurring and human-induced, is an ongoing issue, Deforestation causes extinction, changes to climatic conditions, desertification, and displacement of populations as observed by current conditions and in the past through the fossil record. More than half of all plant and land animal species in the live in tropical forests. Between 2000 and 2012,2.3 million square kilometres of forests around the world were cut down, as a result of deforestation, only 6.2 million square kilometres remain of the original 16 million square kilometres of forest that formerly covered the Earth. According to the United Nations Framework Convention on Climate Change secretariat, subsistence farming is responsible for 48% of deforestation, commercial agriculture is responsible for 32%, logging is responsible for 14%, and fuel wood removals make up 5%. Experts do not agree on whether industrial logging is an important contributor to global deforestation, some argue that poor people are more likely to clear forest because they have no alternatives, others that the poor lack the ability to pay for the materials and labour needed to clear forest. One study found that population increases due to fertility rates were a primary driver of tropical deforestation in only 8% of cases. Other causes of contemporary deforestation may include corruption of government institutions, the distribution of wealth and power, population growth and overpopulation. Globalization is often viewed as another cause of deforestation, though there are cases in which the impacts of globalization have promoted localized forest recovery. The degradation of forest ecosystems has also traced to economic incentives that make forest conversion appear more profitable than forest conservation. Some commentators have noted a shift in the drivers of deforestation over the past 30 years, Deforestation is ongoing and is shaping climate and geography. Deforestation is a contributor to global warming, and is cited as one of the major causes of the enhanced greenhouse effect

Belarus
–
Its capital and most populous city is Minsk. Over 40% of its 207,600 square kilometres is forested and its strongest economic sectors are service industries and manufacturing. In the aftermath of the 1917 Russian Revolution, Belarus declared independence as the Belarusian Peoples Republic, the Socialist Soviet Republic of Byelorussia became a founding constituent republic of the Soviet Union in 1922 and was renamed as the Byelorussian Soviet Socialist Republic. Belarus lost almost half of its territory to Poland after the Polish–Soviet War of 1919–1921, during WWII, military operations devastated Belarus, which lost about a third of its population and more than half of its economic resources. The republic was redeveloped in the post-war years, in 1945 the Byelorussian SSR became a founding member of the United Nations, along with the Soviet Union and the Ukrainian SSR. The parliament of the declared the sovereignty of Belarus on 27 July 1990. Alexander Lukashenko has served as the president since 1994. Belarus has been labeled Europes last dictatorship by some Western journalists, Lukashenko continued a number of Soviet-era policies, such as state ownership of large sections of the economy. Though not directly espousing communism like the five remaining communist countries of China, Cuba, Laos, Vietnam and North Korea, in 2000 Belarus and Russia signed a treaty for greater cooperation, with some hints of forming a Union State. Over 70% of Belaruss population of 9.49 million resides in urban areas, more than 80% of the population is ethnic Belarusian, with sizable minorities of Russians, Poles and Ukrainians. Since a referendum in 1995, the country has had two official languages, Belarusian and Russian, the Constitution of Belarus does not declare any official religion, although the primary religion in the country is Eastern Orthodox Christianity. Belarus is the only European country to retain capital punishment in both law and practice, the name Belarus is closely related with the term Belaya Rus, i. e. White Rus. There are several claims to the origin of the name White Rus, an alternate explanation for the name comments on the white clothing worn by the local Slavic population. A third theory suggests that the old Rus lands that were not conquered by the Tatars had been referred to as white, other sources claim that, before 1267, the land not conquered by the Mongols was considered White Rus. The name Rus is often conflated with its Latin forms Russia and Ruthenia, in some languages, including German and Dutch, the country is generally called White Russia to this day. The Latin term Alba Russia was used again by Pope Pius VI in 1783 to recognize the Society of Jesus there, exclaiming Approbo Societatem Jesu in Alba Russia degentem, approbo, approbo. The first known use of White Russia to refer to Belarus was in the century by Englishman Sir Jerome Horsey. During the 17th century, the Russian tsars used White Rus to describe the lands added from the Grand Duchy of Lithuania

Poland
–
Poland, officially the Republic of Poland, is a country in Central Europe, situated between the Baltic Sea in the north and two mountain ranges in the south. Bordered by Germany to the west, the Czech Republic and Slovakia to the south, Ukraine and Belarus to the east, the total area of Poland is 312,679 square kilometres, making it the 69th largest country in the world and the 9th largest in Europe. With a population of over 38.5 million people, Poland is the 34th most populous country in the world, the 8th most populous country in Europe, Poland is a unitary state divided into 16 administrative subdivisions, and its capital and largest city is Warsaw. Other metropolises include Kraków, Wrocław, Poznań, Gdańsk and Szczecin, the establishment of a Polish state can be traced back to 966, when Mieszko I, ruler of a territory roughly coextensive with that of present-day Poland, converted to Christianity. The Kingdom of Poland was founded in 1025, and in 1569 it cemented a political association with the Grand Duchy of Lithuania by signing the Union of Lublin. This union formed the Polish–Lithuanian Commonwealth, one of the largest and most populous countries of 16th and 17th century Europe, Poland regained its independence in 1918 at the end of World War I, reconstituting much of its historical territory as the Second Polish Republic. In September 1939, World War II started with the invasion of Poland by Nazi Germany, followed thereafter by invasion by the Soviet Union. More than six million Polish citizens died in the war, after the war, Polands borders were shifted westwards under the terms of the Potsdam Conference. With the backing of the Soviet Union, a communist puppet government was formed, and after a referendum in 1946. During the Revolutions of 1989 Polands Communist government was overthrown and Poland adopted a new constitution establishing itself as a democracy, informally called the Third Polish Republic. Since the early 1990s, when the transition to a primarily market-based economy began, Poland has achieved a high ranking on the Human Development Index. Poland is a country, which was categorised by the World Bank as having a high-income economy. Furthermore, it is visited by approximately 16 million tourists every year, Poland is the eighth largest economy in the European Union and was the 6th fastest growing economy on the continent between 2010 and 2015. According to the Global Peace Index for 2014, Poland is ranked 19th in the list of the safest countries in the world to live in. The origin of the name Poland derives from a West Slavic tribe of Polans that inhabited the Warta River basin of the historic Greater Poland region in the 8th century, the origin of the name Polanie itself derives from the western Slavic word pole. In some foreign languages such as Hungarian, Lithuanian, Persian and Turkish the exonym for Poland is Lechites, historians have postulated that throughout Late Antiquity, many distinct ethnic groups populated the regions of what is now Poland. The most famous archaeological find from the prehistory and protohistory of Poland is the Biskupin fortified settlement, dating from the Lusatian culture of the early Iron Age, the Slavic groups who would form Poland migrated to these areas in the second half of the 5th century AD. With the Baptism of Poland the Polish rulers accepted Christianity and the authority of the Roman Church

Balkan mixed forests
–
The Balkan mixed forests constitute a terrestrial ecoregion of Europe according to both the WWF and Digital Map of European Ecological Regions by the European Environment Agency. It belongs in the Temperate broadleaf and mixed forests Biome and the Palearctic ecozone, the climate of the ecoregion is mostly of Köppens humid subtropical to humid warm summer continental type, with wet winters. Some areas of high rainfall have been considered a temperate rainforest relict. The highest peaks support alpine tundra vegetation, phytogeographically, the ecoregion is shared between parts of the Central European, Illyrian and Euxinian provinces of the Circumboreal Region within the Holarctic Kingdom

Geography of Europe
–
Europe is traditionally defined as one of seven continents. Physiographically, it is the peninsula of the larger landmass known as Eurasia, Asia occupies the eastern bulk of this continuous landmass. Europes eastern frontier is delineated by the Ural Mountains in Russia, the southeast boundary with Asia is not universally defined, but the modern definition is generally the Ural River or, less commonly, the Emba River. The boundary continues to the Caspian Sea, the crest of the Caucasus Mountains, the Bosporus, the Sea of Marmara, and the Dardanelles conclude the Asian boundary. The Mediterranean Sea to the south separates Europe from Africa, the western boundary is the Atlantic Ocean. There is ongoing debate on where the centre of Europe falls. Some geographical texts refer to a Eurasian continent given that Europe is not surrounded by sea, in terms of shape, Europe is a collection of connected peninsulas and nearby islands. The two largest peninsulas are mainland Europe and Scandinavia to the north, divided from each other by the Baltic Sea, three smaller peninsulas—Iberia, Italy and the Balkans—emerge from the southern margin of the mainland. The Balkan peninsula is separated from Asia by the Black and Aegean Seas, Italy is separated from the Balkans by the Adriatic Sea, and from Iberia by the Mediterranean Sea, which also separates Europe from Africa. Eastward, mainland Europe widens much like the mouth of a funnel, until the boundary with Asia is reached at the Ural Mountains and Ural River, land relief in Europe shows great variation within relatively small areas. Iceland and the British Isles are special cases, the former is of North Atlantic volcanic formation, while the latter consist of upland areas once joined to the mainland until cut off by rising sea levels. These two halves are separated by the chains of the Pyrenees and the Alps/Carpathians. The northern plains are delimited in the west by the Scandinavian mountains, the major shallow water bodies submerging parts of the northern plains are the Celtic Sea, the North Sea, the Baltic Sea complex, and the Barents Sea. The geology of Europe is hugely varied and complex, and gives rise to the variety of landscapes found across the continent. Figures for the population of Europe vary according to definition of European boundaries is used. The population within the physical geographical boundaries was 731 million in 2005 according to the United Nations. In 2010 the population is 857 million, using a definition which includes the whole of the countries of Russia. Population growth is slow, and median age comparatively high in relation to the worlds other continents
