Slovenia
–
Slovenia, officially the Republic of Slovenia, is a nation state in southern Central Europe, located at the crossroads of main European cultural and trade routes. It is bordered by Italy to the west, Austria to the north, Hungary to the northeast, Croatia to the south and southeast, and it covers 20,273 square kilometers and has a population of 2.06 million. It is a republic and a member of the United Nations, European Union. The capital and largest city is Ljubljana, additionally, the Dinaric Alps and the Pannonian Plain meet on the territory of Slovenia. The country, marked by a significant biological diversity, is one of the most water-rich in Europe, with a river network, a rich aquifer system. Over half of the territory is covered by forest, the human settlement of Slovenia is dispersed and uneven. Slovenia has historically been the crossroads of South Slavic, Germanic, Romance, although the population is not homogeneous, the majority is Slovene. South Slavic language Slovene is the language throughout the country. Slovenia is a largely secularized country, but its culture and identity have been influenced by Catholicism as well as Lutheranism. The economy of Slovenia is small, open, and export-oriented and has strongly influenced by international conditions. It has been hurt by the Eurozone crisis, started in the late 2000s. The main economic field is services, followed by industry and construction, Historically, the current territory of Slovenia was part of many different state formations, including the Roman Empire and the Holy Roman Empire, followed by the Habsburg Monarchy. In October 1918, the Slovenes exercised self-determination for the first time by co-founding the State of Slovenes, Croats, in December 1918, they merged with the Kingdom of Serbia into the Kingdom of Serbs, Croats and Slovenes. During World War II, Slovenia was occupied and annexed by Germany, Italy, and Hungary, with a tiny area transferred to the Independent State of Croatia, in June 1991, after the introduction of multi-party representative democracy, Slovenia split from Yugoslavia and became an independent country. Present-day Slovenia has been inhabited since prehistoric times, and there is evidence of habitation from around 250,000 years ago. A pierced cave bear bone, dating from 43100 ±700 BP, in the 1920s and 1930s, artifacts belonging to the Cro-Magnon such as pierced bones, bone points, and needle were found by archaeologist Srečko Brodar in Potok Cave. It shows that wooden wheels appeared almost simultaneously in Mesopotamia and Europe, in the transition period between the Bronze age to the Iron age, the Urnfield culture flourished. Archaeological remains dating from the Hallstatt period have been found, particularly in southeastern Slovenia, among them a number of situlas in Novo Mesto, in the Iron Age, present-day Slovenia was inhabited by Illyrian and Celtic tribes until the 1st century BC

Sava
–
The Sava is a river in Central and Southeastern Europe, a right tributary of the Danube. It flows through Slovenia, Croatia, along the border of Bosnia and Herzegovina. Its central part is a border of Bosnia-Herzegovina and Croatia. The Sava forms the border of the Balkan Peninsula. The Sava is 990 kilometres long, including the 45-kilometre Sava Dolinka headwater rising in Zelenci and it is the greatest tributary of the Danube by volume of water, and second-largest after Tisza in terms of catchment area and length. It drains a significant portion of the Dinaric Alps region, through the tributaries of Drina, Bosna, Kupa, Una, Vrbas, Lonja, Kolubara, Bosut. The Sava is one of the longest rivers in Europe and among a handful of European rivers of that length that do not drain directly into a sea. The population in the Sava River basin is estimated at 8,176,000, the Sava is navigable for larger vessels from the confluence of the Kupa River in Sisak, Croatia, approximately two-thirds of its length. The Sava River is formed from the Sava Dolinka and the Sava Bohinjka headwaters in northwest Slovenia, the Sava Dolinka rises at the Zelenci Pools near Kranjska Gora, Slovenia, in a valley separating the Julian Alps from the Karavanke mountain range. The spring is located near the Slovene-Italian border at 833 metres above sea level, the Sava Dolinka spring is fed by groundwater possibly exhibiting bifurcation of source karst aquifer to the Sava and Soča basins. Nadiža creek, a losing stream flowing nearby, is the source of Zelenci Pools water. The Sava Dolinka is considered the Savas initial, 45-kilometre segment, the Sava Bohinjka originates in Ribčev Laz, at the confluence of the Jezernica, a short watercourse flowing out from Lake Bohinj and the Mostnica River. The watercourse flows 41 kilometres —including the length of the Savica—east to Radovljica, downstream from the confluence, the river is referred to as the Sava. The Sava is located in Southeast Europe, flowing through Slovenia, Croatia, Serbia and its total length is 990 kilometres, including the 45-kilometre Sava Dolinka and the 945-kilometre Sava proper. As a right tributary of the Danube, the river belongs to the Black Sea drainage basin and it is also the largest tributary of the Danube by discharge. The river course is used to describe the northern boundary of the Balkans. Before the breakup of Yugoslavia in 1991, the river was located completely inside Yugoslav borders, downstream of Radovljica, the Sava proceeds southeast towards Kranj. Between Kranj and Medvode, its course comprises the Lake Trboje and the Lake Zbilje reservoirs, built for the Mavčiče, the Sava then flows through the capital of Slovenia, Ljubljana, where another reservoir is located on the river, adjacent to the Tacen Whitewater Course

Danube
–
The Danube is Europes second-longest river, after the Volga River, and also the longest river in the European Union region. It is located in Central and Eastern Europe, the Danube was once a long-standing frontier of the Roman Empire, and today flows through 10 countries, more than any other river in the world. Its drainage basin extends into nine more countries, the Latin name Dānuvius is one of a number of Old European river names derived from a Proto-Indo-European *dānu. Other river names from the root include the Dunajec, Dzvina/Daugava, Don, Donets, Dnieper, Dniestr. In Rigvedic Sanskrit, dānu means fluid, drop, in Avestan, in the Rigveda, Dānu once appears as the mother of Vrtra. Known to the ancient Greeks as the Istros a borrowing from a Daco-Thracian name meaning strong, in Latin, the Danube was variously known as Danubius, Danuvius or as Ister. The Dacian/Thracian name was Donaris for the upper Danube and Istros for the lower Danube, the Thraco-Phrygian name was Matoas, the bringer of luck. The Latin name is masculine, as are all its Slavic names, the German Donau is feminine, as it has been re-interpreted as containing the suffix -ouwe wetland. Classified as a waterway, it originates in the town of Donaueschingen, in the Black Forest of Germany, at the confluence of the rivers Brigach. The Danube then flows southeast for about 2,800 km, passing through four capital cities before emptying into the Black Sea via the Danube Delta in Romania and its drainage basin extends into nine more. The highest point of the basin is the summit of Piz Bernina at the Italy–Switzerland border. The land drained by the Danube extends into other countries. Many Danubian tributaries are important rivers in their own right, navigable by barges, from its source to its outlet into the Black Sea, its main tributaries are, The Danube flows through many cities, including four national capitals, more than any other river in the world. Danube remains a mountain river until Passau, with average bottom gradient 0. 0012%. Middle Section, From Devín Gate to Iron Gate, at the border of Serbia and Romania, the riverbed widens and the average bottom gradient becomes only 0. 00006%. Lower Section, From Iron Gate to Sulina, with average gradient as little as 0. 00003%, about 60 of its tributaries are also navigable. In 1994 the Danube was declared one of ten Pan-European transport corridors, routes in Central, the amount of goods transported on the Danube increased to about 100 million tons in 1987. In 1999, transport on the river was difficult by the NATO bombing of three bridges in Serbia during the Kosovo War

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

River
–
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases a river flows into the ground and becomes dry at the end of its course without reaching another body of water, small rivers can be referred to using names such as stream, creek, brook, rivulet, and rill. There are no official definitions for the term river as applied to geographic features. Many names for small rivers are specific to geographic location, examples are run in parts of the United States, burn in Scotland and northeast England. Sometimes a river is defined as being larger than a creek, but not always, Rivers are part of the hydrological cycle. Potamology is the study of rivers while limnology is the study of inland waters in general. Extraterrestrial rivers of liquid hydrocarbons have recently found on Titan. Channels may indicate past rivers on other planets, specifically outflow channels on Mars and rivers are theorised to exist on planets, a river begins at a source, follows a path called a course, and ends at a mouth or mouths. The water in a river is confined to a channel. In larger rivers there is also a wider floodplain shaped by flood-waters over-topping the channel. Floodplains may be wide in relation to the size of the river channel. This distinction between river channel and floodplain can be blurred, especially in areas where the floodplain of a river channel can become greatly developed by housing. Rivers can flow down mountains, through valleys or along plains, the term upriver refers to the direction towards the source of the river, i. e. against the direction of flow. Likewise, the term describes the direction towards the mouth of the river. The term left bank refers to the bank in the direction of flow. The river channel typically contains a stream of water, but some rivers flow as several interconnecting streams of water. Extensive braided rivers are now found in only a few regions worldwide and they also occur on peneplains and some of the larger river deltas. Anastamosing rivers are similar to braided rivers and are quite rare

Karst
–
Karst topography is a landscape formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves and it has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes, the English word karst was borrowed from German Karst in the late 19th century. The German word came into use before the 19th century, according to the prevalent interpretation, the term is derived from the German name for the Karst region, a limestone plateau above the city of Trieste in the northern Adriatic. Scholars disagree, however, on whether the German word was borrowed from Slovene, the Slovene common noun kras was first attested in the 18th century, and the adjective form kraški in the 16th century. The Slovene words arose through metathesis from the reconstructed form *korsъ, ultimately, the word is of Mediterranean origin, believed to derive from some Romanized Illyrian base. It has been suggested that the word may derive from the Proto-Indo-European root karra- rock, the name may also be connected to the oronym Karsádios oros cited by Ptolemy, and perhaps also to Latin Carusardius. The development of karst occurs whenever acidic water starts to break down the surface of bedrock near its cracks, as the bedrock continues to degrade, its cracks tend to get bigger. As time goes on, these fractures will become wider, if this underground drainage system does form, it will speed up the development of karst formations there because more water will be able to flow through the region, giving it more erosive power. The carbonic acid that causes karstic features is formed as rain passes through the atmosphere picking up carbon dioxide, once the rain reaches the ground, it may pass through soil that can provide much more CO2 to form a weak carbonic acid solution, which dissolves calcium carbonate. The oxidation of sulfides leading to the formation of acid can also be one of the corrosion factors in karst formation. As oxygen -rich surface waters seep into deep anoxic karst systems, they bring oxygen, sulfuric acid then reacts with calcium carbonate, causing increased erosion within the limestone formation. This chain of reactions is, This reaction chain forms gypsum, the karstification of a landscape may result in a variety of large- or small-scale features both on the surface and beneath. On exposed surfaces, small features may include solution flutes, runnels, limestone pavement, medium-sized surface features may include sinkholes or cenotes, vertical shafts, foibe, disappearing streams, and reappearing springs. Large-scale features may include limestone pavements, poljes, and karst valleys, mature karst landscapes, where more bedrock has been removed than remains, may result in karst towers, or haystack/eggbox landscapes. Beneath the surface, complex underground systems and extensive caves. Some of the most dramatic of these formations can be seen in Thailands Phangnga Bay, calcium carbonate dissolved into water may precipitate out where the water discharges some of its dissolved carbon dioxide. Rivers which emerge from springs may produce tufa terraces, consisting of layers of calcite deposited over extended periods of time, in caves, a variety of features collectively called speleothems are formed by deposition of calcium carbonate and other dissolved minerals
7.
Cave
–
A cave is a hollow place in the ground, specifically a natural underground space large enough for a human to enter. Caves form naturally by the weathering of rock and often extend deep underground, the word cave can also refer to much smaller openings such as sea caves, rock shelters, and grottos. A cavern is a type of cave, naturally formed in soluble rock with the ability to grow speleothems. Speleology is the science of exploration and study of all aspects of caves, visiting or exploring caves for recreation may be called caving, potholing, or spelunking. The formation and development of caves is known as speleogenesis, which can occur over the course of millions of years, caves are formed by various geologic processes and can be variable sizes. These may involve a combination of processes, erosion from water, tectonic forces, microorganisms, pressure. Isotopic dating techniques can be applied to cave sediments, in order to determine the timescale when geologic events may have occurred to help form and it is estimated that the maximum depth of a cave cannot be more than 3,000 metres due to the pressure of overlying rocks. For karst caves the maximum depth is determined on the basis of the limit of karst forming processes. Most caves are formed in limestone by dissolution, solutional caves or karst caves are the most frequently occurring caves and such caves form in rock that is soluble. Most occur in limestone, but they can form in other rocks including chalk, dolomite, marble, salt. Rock is dissolved by acid in groundwater that seeps through bedding planes, faults, joints. Over geological epochs cracks expand to become caves and cave systems, the largest and most abundant solutional caves are located in limestone. Limestone dissolves under the action of rainwater and groundwater charged with H2CO3, the dissolution process produces a distinctive landform known as karst, characterized by sinkholes and underground drainage. Limestone caves are often adorned with calcium carbonate formations produced through slow precipitation and these include flowstones, stalactites, stalagmites, helictites, soda straws and columns. These secondary mineral deposits in caves are called speleothems, the portions of a solutional cave that are below the water table or the local level of the groundwater will be flooded. Lechuguilla Cave in New Mexico and nearby Carlsbad Cavern are now believed to be examples of type of solutional cave. They were formed by H2S gas rising from below, where reservoirs of oil give off sulfurous fumes and this gas mixes with ground water and forms H2SO4. The acid then dissolves the limestone from below, rather than from above, caves formed at the same time as the surrounding rock are called primary caves

Stone Age
–
The Stone Age was a broad prehistoric period during which stone was widely used to make implements with an edge, a point, or a percussion surface. The period lasted roughly 3.4 million years, and ended between 8700 BCE and 2000 BCE with the advent of metalworking, bone tools were used during this period as well but are rarely preserved in the archaeological record. The Stone Age is further subdivided by the types of tools in use. According to the age and location of the current evidence, the cradle of the genus is the East African Rift System, especially toward the north in Ethiopia, where it is bordered by grasslands. The closest relative among the living primates, the genus Pan, represents a branch that continued on in the deep forest. The rift served as a conduit for movement into southern Africa and also north down the Nile into North Africa and through the continuation of the rift in the Levant to the vast grasslands of Asia. The oldest indirect evidence found of stone tool use is fossilised animal bones with tool marks, the oldest stone tools were excavated from the site of Lomekwi 3 in West Turkana, northwestern Kenya, and date to 3.3 million years old. Prior to the discovery of these Lomekwian tools, the oldest known stone tools had been found at sites at Gona, Ethiopia, on the sediments of the paleo-Awash River. All the tools come from the Busidama Formation, which lies above a disconformity, or missing layer, the oldest sites containing tools are dated to 2. 6–2.55 mya. One of the most striking circumstances about these sites is that they are from the Late Pliocene, excavators at the locality point out that. the earliest stone tool makers were skilled flintknappers. The possible reasons behind this seeming abrupt transition from the absence of tools to the presence thereof include. The species who made the Pliocene tools remains unknown, fragments of Australopithecus garhi, Australopithecus aethiopicus and Homo, possibly Homo habilis, have been found in sites near the age of the Gona tools. Innovation of the technique of smelting ore ended the Stone Age, the first most significant metal manufactured was bronze, an alloy of copper and tin, each of which was smelted separately. The Chalcolithic by convention is the period of the Bronze Age. The Bronze Age was followed by the Iron Age, the transition out of the Stone Age occurred between 6000 BCE and 2500 BCE for much of humanity living in North Africa and Eurasia. Note the Rudna Glava mine in Serbia, Ötzi the Iceman, a mummy from about 3300 BCE carried with him a copper axe and a flint knife. In regions such as Sub-Saharan Africa, the Stone Age was followed directly by the Iron Age, the Middle East and southeastern Asian regions progressed past Stone Age technology around 6000 BCE. Europe, and the rest of Asia became post–Stone Age societies by about 4000 BCE, the proto-Inca cultures of South America continued at a Stone Age level until around 2000 BCE, when gold, copper and silver made their entrance

Renaissance
–
The Renaissance was a period in European history, from the 14th to the 17th century, regarded as the cultural bridge between the Middle Ages and modern history. It started as a movement in Italy in the Late Medieval period and later spread to the rest of Europe. This new thinking became manifest in art, architecture, politics, science, Early examples were the development of perspective in oil painting and the recycled knowledge of how to make concrete. Although the invention of movable type sped the dissemination of ideas from the later 15th century. In politics, the Renaissance contributed to the development of the customs and conventions of diplomacy, the Renaissance began in Florence, in the 14th century. Other major centres were northern Italian city-states such as Venice, Genoa, Milan, Bologna, the word Renaissance, literally meaning Rebirth in French, first appeared in English in the 1830s. The word also occurs in Jules Michelets 1855 work, Histoire de France, the word Renaissance has also been extended to other historical and cultural movements, such as the Carolingian Renaissance and the Renaissance of the 12th century. The Renaissance was a movement that profoundly affected European intellectual life in the early modern period. Renaissance scholars employed the humanist method in study, and searched for realism, however, a subtle shift took place in the way that intellectuals approached religion that was reflected in many other areas of cultural life. In addition, many Greek Christian works, including the Greek New Testament, were back from Byzantium to Western Europe. Political philosophers, most famously Niccolò Machiavelli, sought to describe life as it really was. Others see more competition between artists and polymaths such as Brunelleschi, Ghiberti, Donatello, and Masaccio for artistic commissions as sparking the creativity of the Renaissance. Yet it remains much debated why the Renaissance began in Italy, accordingly, several theories have been put forward to explain its origins. During the Renaissance, money and art went hand in hand, Artists depended entirely on patrons while the patrons needed money to foster artistic talent. Wealth was brought to Italy in the 14th, 15th, and 16th centuries by expanding trade into Asia, silver mining in Tyrol increased the flow of money. Luxuries from the Eastern world, brought home during the Crusades, increased the prosperity of Genoa, unlike with Latin texts, which had been preserved and studied in Western Europe since late antiquity, the study of ancient Greek texts was very limited in medieval Western Europe. One of the greatest achievements of Renaissance scholars was to bring this entire class of Greek cultural works back into Western Europe for the first time since late antiquity, Arab logicians had inherited Greek ideas after they had invaded and conquered Egypt and the Levant. Their translations and commentaries on these ideas worked their way through the Arab West into Spain and Sicily and this work of translation from Islamic culture, though largely unplanned and disorganized, constituted one of the greatest transmissions of ideas in history

Ancient Rome
–
In its many centuries of existence, the Roman state evolved from a monarchy to a classical republic and then to an increasingly autocratic empire. Through conquest and assimilation, it came to dominate the Mediterranean region and then Western Europe, Asia Minor, North Africa and it is often grouped into classical antiquity together with ancient Greece, and their similar cultures and societies are known as the Greco-Roman world. Ancient Roman civilisation has contributed to modern government, law, politics, engineering, art, literature, architecture, technology, warfare, religion, language and society. Rome professionalised and expanded its military and created a system of government called res publica, the inspiration for modern republics such as the United States and France. By the end of the Republic, Rome had conquered the lands around the Mediterranean and beyond, its domain extended from the Atlantic to Arabia, the Roman Empire emerged with the end of the Republic and the dictatorship of Augustus Caesar. 721 years of Roman-Persian Wars started in 92 BC with their first war against Parthia and it would become the longest conflict in human history, and have major lasting effects and consequences for both empires. Under Trajan, the Empire reached its territorial peak, Republican mores and traditions started to decline during the imperial period, with civil wars becoming a prelude common to the rise of a new emperor. Splinter states, such as the Palmyrene Empire, would divide the Empire during the crisis of the 3rd century. Plagued by internal instability and attacked by various migrating peoples, the part of the empire broke up into independent kingdoms in the 5th century. This splintering is a landmark historians use to divide the ancient period of history from the pre-medieval Dark Ages of Europe. King Numitor was deposed from his throne by his brother, Amulius, while Numitors daughter, Rhea Silvia, because Rhea Silvia was raped and impregnated by Mars, the Roman god of war, the twins were considered half-divine. The new king, Amulius, feared Romulus and Remus would take back the throne, a she-wolf saved and raised them, and when they were old enough, they returned the throne of Alba Longa to Numitor. Romulus became the source of the citys name, in order to attract people to the city, Rome became a sanctuary for the indigent, exiled, and unwanted. This caused a problem for Rome, which had a large workforce but was bereft of women, Romulus traveled to the neighboring towns and tribes and attempted to secure marriage rights, but as Rome was so full of undesirables they all refused. Legend says that the Latins invited the Sabines to a festival and stole their unmarried maidens, leading to the integration of the Latins, after a long time in rough seas, they landed at the banks of the Tiber River. Not long after they landed, the men wanted to take to the sea again, one woman, named Roma, suggested that the women burn the ships out at sea to prevent them from leaving. At first, the men were angry with Roma, but they realized that they were in the ideal place to settle. They named the settlement after the woman who torched their ships, the Roman poet Virgil recounted this legend in his classical epic poem the Aeneid
