Metropolitan France
–
Metropolitan France, also known as European France, is the part of France in Europe. It comprises mainland France and nearby islands in the Atlantic Ocean, the English Channel, Overseas France is the collective name for the part of France outside Europe, French overseas regions, territories, collectivities, and the sui generis collectivity of New Caledonia. Metropolitan France and Overseas France together form the French Republic, Metropolitan France accounts for 82. 2% of the land territory,3. 3% of the exclusive economic zone, and 95. 9% of the population of the French Republic. The five overseas regions—Martinique, Guadeloupe, Réunion, French Guiana, in overseas France, a person from metropolitan France is often called a métro, short for métropolitain. Similar terms existed to describe other European colonial powers and this usage of the words metropolis and metropolitan itself came from Ancient Greek metropolis, which was the name for a city-state from which originated colonies across the Mediterranean. By extension metropolis and metropolitan came to mean motherland, a nation or country as opposed to its colonies overseas, today there are some people in overseas France who object to the use of the term la France métropolitaine due to its colonial origins. They prefer to call it the European territory of France, as the Treaties of the European Union do, likewise, they oppose treating overseas France and metropolitan France as separate entities. As a result, since the end of the 1990s INSEE has included the five departments in its figures for France. Other branches of the French administration may have different definitions of what la France entière is, the World Bank refers to this as France only, and not the whole of France as INSEE does. According to the French government,64,860,000 people lived in metropolitan France as of January 2017, Metropolitan France covers a land area of 551,695 km². At sea, the economic zone of metropolitan France covers 334,604 km², while the EEZ of overseas France covers 9,821,231 km². In the second round of the 2007 French presidential election,37,342,004 French people cast a ballot. 35,907,015 of these cast their ballots in metropolitan France,1,088,679 cast their ballots in overseas France, and 346,310 cast their ballots in foreign countries. The French National Assembly is made up of 577 deputies,539 of whom are elected in metropolitan France,27 in overseas France, and 11 by French citizens living in foreign countries. Mainland France, or just the mainland, does not include the French islands in the Atlantic Ocean, English Channel or Mediterranean Sea, in Corsica, people from the mainland part of Metropolitan France are referred to as les continentaux. A casual synonym for the part of Metropolitan France is lHexagone, for its approximate shape. French colonial empire Mainland Wildlife of Metropolitan France

Estuary
–
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a zone between river environments and maritime environments. They are subject both to marine influences—such as tides, waves, and the influx of saline water—and to riverine influences—such as flows of fresh water and sediment. The inflows of sea water and fresh water provide high levels of nutrients both in the water column and in sediment, making estuaries among the most productive natural habitats in the world. Most existing estuaries formed during the Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea began to rise about 10. Estuaries are typically classified according to their geomorphological features or to water-circulation patterns, the banks of many estuaries are amongst the most heavily populated areas of the world, with about 60% of the worlds population living along estuaries and the coast. The word estuary is derived from the Latin word aestuarium meaning tidal inlet of the sea, there have been many definitions proposed to describe an estuary. However, this definition excludes a number of water bodies such as coastal lagoons. This broad definition also includes fjords, lagoons, river mouths, an estuary is a dynamic ecosystem having a connection to the open sea through which the sea water enters with the rhythm of the tides. The sea water entering the estuary is diluted by the water flowing from rivers. The pattern of dilution varies between different estuaries and depends on the volume of water, the tidal range. Drowned river valleys are known as coastal plain estuaries. In places where the sea level is rising relative to the land, sea water progressively penetrates into river valleys and this is the most common type of estuary in temperate climates. Well-studied estuaries include the Severn Estuary in the United Kingdom and the Ems Dollard along the Dutch-German border, the width-to-depth ratio of these estuaries is typically large, appearing wedge-shaped in the inner part and broadening and deepening seaward. Water depths rarely exceed 30 m, examples of this type of estuary in the U. S. are the Hudson River, Chesapeake Bay, and Delaware Bay along the Mid-Atlantic coast, and Galveston Bay and Tampa Bay along the Gulf Coast. They are relatively common in tropical and subtropical locations and these estuaries are semi-isolated from ocean waters by barrier beaches. Formation of barrier beaches partially encloses the estuary, with only narrow inlets allowing contact with the ocean waters, bar-built estuaries typically develop on gently sloping plains located along tectonically stable edges of continents and marginal sea coasts. They are extensive along the Atlantic and Gulf coasts of the U. S. in areas with active coastal deposition of sediments, barrier beaches form in shallow water and are generally parallel to the shoreline, resulting in long, narrow estuaries

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

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

River delta
–
A river delta is a landform that forms from deposition of sediment carried by a river as the flow leaves its mouth and enters slower-moving or standing water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, River deltas are ecologically important as they provide coastline defense, are home to many species, and can impact drinking water supply. The tidal currents also cannot be too strong, as sediment would wash out into the body faster than the river deposits it. Of course, the river must carry enough sediment to layer into deltas over time, the rivers velocity decreases rapidly, causing it to deposit the majority, if not all, of its load. This alluvium builds up to form the river delta, when the flow enters the standing water, it is no longer confined to its channel and expands in width. This flow expansion results in a decrease in the flow velocity, as a result, sediment drops out of the flow and deposits. Over time, this single channel builds a deltaic lobe, pushing its mouth into the standing water, as the deltaic lobe advances, the gradient of the river channel becomes lower because the river channel is longer but has the same change in elevation. As the slope of the channel decreases, it becomes unstable for two reasons. First, gravity makes the flow in the most direct course down slope. If the river breaches its natural levees, it out onto a new course with a shorter route to the ocean. Second, as its slope gets lower, the amount of stress on the bed decreases, which results in deposition of sediment within the channel. This makes it easier for the river to breach its levees, often when the channel does this, some of its flow remains in the abandoned channel. When these channel-switching events occur, a mature delta develops a distributary network, another way these distributary networks form is from deposition of mouth bars. When this mid-channel bar is deposited at the mouth of a river and this results in additional deposition on the upstream end of the mouth-bar, which splits the river into two distributary channels. A good example of the result of this process is the Wax Lake Delta, in both of these cases, depositional processes force redistribution of deposition from areas of high deposition to areas of low deposition. This results in the smoothing of the shape of the delta as the channels move across its surface. Because the sediment is laid down in fashion, the shape of these deltas approximates a fan. The more often the flow changes course, the shape develops as closer to an ideal fan, the Mississippi and Ural River deltas, with their birds-feet, are examples of rivers that do not avulse often enough to form a symmetrical fan shape

Mont Blanc
–
Mont Blanc or Monte Bianco, both meaning White Mountain, is the highest mountain in the Alps and the highest in Europe west of Russia after the Caucasus peaks. It rises 4,808 m above sea level and is ranked 11th in the world in topographic prominence, the mountain lies in a range called the Graian Alps, between the regions of Aosta Valley, Italy, and Savoie and Haute-Savoie, France. The location of the summit is on the line between the valleys of Ferret and Veny in Italy and the valleys of Montjoie, and Arve in France. The Mont Blanc massif is popular for mountaineering, hiking, skiing, the three towns and their communes which surround Mont Blanc are Courmayeur in Aosta Valley, Italy, and Saint-Gervais-les-Bains and Chamonix in Haute-Savoie, France. The latter town was the site of the first Winter Olympics, a cable car ascends and crosses the mountain range from Courmayeur to Chamonix, through the Col du Géant. The 11.6 km Mont Blanc Tunnel, constructed between 1957 and 1965, runs beneath the mountain and is a major transport route. The first recorded ascent of Mont Blanc was on 8 August 1786 by Jacques Balmat and this climb, initiated by Horace-Bénédict de Saussure, who gave a reward for the successful ascent, traditionally marks the start of modern mountaineering. The first woman to reach the summit was Marie Paradis in 1808, nowadays the summit is ascended by an average of 20,000 mountaineer-tourists each year. It could be considered an easy, yet arduous, ascent for someone who is well-trained and acclimatized to the altitude, from lAiguille du Midi, Mont Blanc seems quite close, being 1,000 m higher. Some routes require knowledge of mountaineering, a guide. All routes are long and arduous, involving delicate passages and the hazard of rock-fall or avalanche, climbers may also suffer altitude sickness, occasionally life threatening, particularly if they do not acclimatize to it. Since the French Revolution, the issue of the ownership of the summit has been debated, from 1416 to 1792, the entire mountain was within the Duchy of Savoy. In 1723 the Duke of Savoy, Victor Amadeus II, acquired the Kingdom of Sardinia, the resulting state of Sardinia was to become preeminent in the Italian unification. In September 1792, the French revolutionary Army of the Alps under Anne-Pierre de Montesquiou-Fézensac seized Savoy without much resistance, in a treaty of 15 May 1796, Victor Amadeus III of Sardinia was forced to cede Savoy and Nice to France. This act further states that the border should be visible from the town of Chamonix, however, neither the peak of the Mont Blanc is visible from Courmayeur nor the peak of the Mont Blanc de Courmayeur is visible from Chamonix because part of the mountains lower down obscure them. After the Napoleonic Wars, the Congress of Vienna restored the King of Sardinia in Savoy, Nice and Piedmont, his traditional territories, forty-five years later, after the Second Italian War of Independence, it was replaced by a new legal act. This act was signed in Turin on 24 March 1860 by Napoleon III and Victor Emmanuel II of Savoy, a demarcation agreement, signed on 7 March 1861, defined the new border. With the formation of Italy, for the first time Mont Blanc was located on the border of France, the 1860 act and attached maps are still legally valid for both the French and Italian governments

Coal
–
Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers or veins called coal beds or coal seams. The harder forms, such as coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure. Coal is composed primarily of carbon, along with quantities of other elements, chiefly hydrogen, sulfur, oxygen. A fossil fuel, coal forms when plant matter is converted into peat, which in turn is converted into lignite, then sub-bituminous coal, after that bituminous coal. This involves biological and geological processes that take place over time, throughout history, coal has been used as an energy resource, primarily burned for the production of electricity and heat, and is also used for industrial purposes, such as refining metals. Coal is the largest source of energy for the generation of electricity worldwide, the extraction of coal, its use in energy production and its byproducts are all associated with environmental and health effects including climate change. Coal is extracted from the ground by coal mining, since 1983, the worlds top coal producer has been China. In 2015 China produced 3,747 million tonnes of coal –47. 7% of 7,861 million tonnes world coal production, in 2015 other large producers were United States, India, European Union and Australia. The word originally took the col in Old English, from Proto-Germanic *kula. In Old Turkic languages, kül is ash, cinders, öčür is quench, the compound charcoal in Turkic is öčür kül, literally quenched ashes, cinders, coals with elided anlaut ö- and inflection affixes -ülmüş. At various times in the geologic past, the Earth had dense forests in low-lying wetland areas, due to natural processes such as flooding, these forests were buried underneath soil. As more and more soil deposited over them, they were compressed, the temperature also rose as they sank deeper and deeper. As the process continued the plant matter was protected from biodegradation and oxidation and this trapped the carbon in immense peat bogs that were eventually covered and deeply buried by sediments. Under high pressure and high temperature, dead vegetation was slowly converted to coal, as coal contains mainly carbon, the conversion of dead vegetation into coal is called carbonization. The wide, shallow seas of the Carboniferous Period provided ideal conditions for coal formation, the exception is the coal gap in the Permian–Triassic extinction event, where coal is rare. Coal is known from Precambrian strata, which predate land plants — this coal is presumed to have originated from residues of algae, in its dehydrated form, peat is a highly effective absorbent for fuel and oil spills on land and water. It is also used as a conditioner for soil to make it able to retain. Lignite, or brown coal, is the lowest rank of coal, jet, a compact form of lignite, is sometimes polished and has been used as an ornamental stone since the Upper Palaeolithic

Iron ore
–
Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are rich in iron oxides and vary in color from dark grey, bright yellow. The iron itself is found in the form of magnetite, hematite, goethite, limonite or siderite. Ores containing very high quantities of hematite or magnetite are known as ore or direct shipping ore. Iron ore is the raw material used to make pig iron, indeed, it has been argued that iron ore is more integral to the global economy than any other commodity, except perhaps oil. Metallic iron is virtually unknown on the surface of the Earth except as iron-nickel alloys from meteorites, although iron is the fourth most abundant element in the Earths crust, comprising about 5%, the vast majority is bound in silicate or more rarely carbonate minerals. Prior to the revolution, most iron was obtained from widely available goethite or bog ore, for example during the American Revolution. Prehistoric societies used laterite as a source of iron ore, historically, much of the iron ore utilized by industrialized societies has been mined from predominantly hematite deposits with grades of around 70% Fe. These deposits are referred to as direct shipping ores or natural ores. Iron-ore mining methods vary by the type of ore being mined, there are four main types of iron-ore deposits worked currently, depending on the mineralogy and geology of the ore deposits. These are magnetite, titanomagnetite, massive hematite and pisolitic ironstone deposits, banded iron formations are sedimentary rocks containing more than 15% iron composed predominantly of thinly bedded iron minerals and silica. Banded iron formations occur exclusively in Precambrian rocks, and are weakly to intensely metamorphosed. Banded iron formations may contain iron in carbonates or silicates, banded iron formations are known as taconite within North America. The mining involves moving tremendous amounts of ore and waste, the waste comes in two forms, non-ore bedrock in the mine, and unwanted minerals which are an intrinsic part of the ore rock itself. The mullock is mined and piled in dumps, and the gangue is separated during the beneficiation process and is removed as tailings. Taconite tailings are mostly the mineral quartz, which is chemically inert and this material is stored in large, regulated water settling ponds. The typical magnetite iron-ore concentrate has less than 0. 1% phosphorus, 3–7% silica, currently magnetite iron ore is mined in Minnesota and Michigan in the U. S. Direct-shipping iron-ore deposits are exploited on all continents except Antarctica, with the largest intensity in South America

Bauxite
–
Bauxite, an aluminium ore, is the worlds main source of aluminium. It consists mostly of the minerals gibbsite, boehmite and diaspore, mixed with the two iron oxides goethite and haematite, the mineral kaolinite and small amounts of anatase. In 1821 the French geologist Pierre Berthier discovered bauxite near the village of Les Baux in Provence, in 1861, French chemist Henri Sainte-Claire Deville named the mineral bauxite. Lateritic bauxites are distinguished from karst bauxite ores, the lateritic bauxites are found mostly in the countries of the tropics. They were formed by lateritization of various silicate rocks such as granite, gneiss, basalt, syenite, in comparison with the iron-rich laterites, the formation of bauxites depends even more on intense weathering conditions in a location with very good drainage. This enables the dissolution of the kaolinite and the precipitation of the gibbsite, zones with highest aluminium content are frequently located below a ferruginous surface layer. The aluminium hydroxide in the bauxite deposits is almost exclusively gibbsite. In 2009, Australia was the top producer of bauxite with almost one-third of the production, followed by China, Brazil, India. Although aluminium demand is increasing, known reserves of its bauxite ore are sufficient to meet the worldwide demands for aluminium for many centuries. Increased aluminium recycling, which has the advantage of lowering the cost in power in producing aluminium. In November 2010, Nguyen Tan Dung, the minister of Vietnam, announced that Vietnams bauxite reserves might total 11000 Mt. Bauxite is usually strip mined because it is almost always found near the surface of the terrain, as of 2010, approximately 70% to 80% of the worlds dry bauxite production is processed first into alumina and then into aluminium by electrolysis. Bauxite rocks are classified according to their intended commercial application, metallurgical, abrasive, cement, chemical. Usually, bauxite ore is heated in a vessel along with a sodium hydroxide solution at a temperature of 150 to 200 °C. At these temperatures, the aluminium is dissolved as sodium aluminate, the aluminium compounds in the bauxite may be present as gibbsite, boehmite or diaspore, the different forms of the aluminium component will dictate the extraction conditions. The undissolved waste, bauxite tailings, after the aluminium compounds are extracted contains iron oxides, silica, calcia, titania, after separation of the residue by filtering, pure gibbsite is precipitated when the liquid is cooled, and then seeded with fine-grained aluminium hydroxide. The gibbsite is usually converted into aluminium oxide, Al2O3, by heating in rotary kilns or fluid flash calciners to a temperature in excess of 1000oC and this aluminium oxide is dissolved at a temperature of about 960 °C in molten cryolite. Prior to the invention of this process in 1886, elemental aluminium was made by heating ore along with sodium or potassium in a vacuum

Zinc
–
Zinc is a chemical element with the symbol Zn and atomic number 30. It is the first element in group 12 of the periodic table, in some respects zinc is chemically similar to magnesium, both elements exhibit only one normal oxidation state, and the Zn2+ and Mg2+ ions are of similar size. Zinc is the 24th most abundant element in Earths crust and has five stable isotopes, the most common zinc ore is sphalerite, a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States, Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity. Zinc metal was not produced on a large scale until the 12th century in India and was unknown to Europe until the end of the 16th century, the mines of Rajasthan have given definite evidence of zinc production going back to the 6th century BC. To date, the oldest evidence of pure zinc comes from Zawar, in Rajasthan, alchemists burned zinc in air to form what they called philosophers wool or white snow. The element was named by the alchemist Paracelsus after the German word Zinke. German chemist Andreas Sigismund Marggraf is credited with discovering pure metallic zinc in 1746, work by Luigi Galvani and Alessandro Volta uncovered the electrochemical properties of zinc by 1800. Corrosion-resistant zinc plating of iron is the application for zinc. Other applications are in batteries, small non-structural castings. A variety of compounds are commonly used, such as zinc carbonate and zinc gluconate, zinc chloride, zinc pyrithione, zinc sulfide. Zinc is an essential mineral perceived by the public today as being of exceptional biologic and public health importance, Zinc deficiency affects about two billion people in the developing world and is associated with many diseases. In children, deficiency causes growth retardation, delayed sexual maturation, infection susceptibility, enzymes with a zinc atom in the reactive center are widespread in biochemistry, such as alcohol dehydrogenase in humans. Consumption of excess zinc can cause ataxia, lethargy and copper deficiency, Zinc is a bluish-white, lustrous, diamagnetic metal, though most common commercial grades of the metal have a dull finish.6 pm. The metal is hard and brittle at most temperatures but becomes malleable between 100 and 150 °C, above 210 °C, the metal becomes brittle again and can be pulverized by beating. Zinc is a conductor of electricity. For a metal, zinc has relatively low melting and boiling points, the melting point is the lowest of all the transition metals aside from mercury and cadmium. Many alloys contain zinc, including brass, Other metals long known to form binary alloys with zinc are aluminium, antimony, bismuth, gold, iron, lead, mercury, silver, tin, magnesium, cobalt, nickel, tellurium, and sodium

Uranium
–
Uranium is a chemical element with symbol U and atomic number 92. It is a metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons, Uranium is weakly radioactive because all its isotopes are unstable. The most common isotopes in natural uranium are uranium-238 and uranium-235, Uranium has the highest atomic weight of the primordially occurring elements. Its density is about 70% higher than that of lead, and it occurs naturally in low concentrations of a few parts per million in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite. In nature, uranium is found as uranium-238, uranium-235, Uranium decays slowly by emitting an alpha particle. The half-life of uranium-238 is about 4.47 billion years, many contemporary uses of uranium exploit its unique nuclear properties. Uranium-235 is the naturally occurring fissile isotope, which makes it widely used in nuclear power plants. However, because of the amounts found in nature, uranium needs to undergo enrichment so that enough uranium-235 is present. Uranium-238 is fissionable by fast neutrons, and is fertile, meaning it can be transmuted to fissile plutonium-239 in a nuclear reactor, another fissile isotope, uranium-233, can be produced from natural thorium and is also important in nuclear technology. In sufficient concentration, these maintain a sustained nuclear chain reaction. This generates the heat in nuclear reactors, and produces the fissile material for nuclear weapons. Depleted uranium is used in kinetic energy penetrators and armor plating, Uranium is used as a colorant in uranium glass, producing lemon yellow to green colors. Uranium glass fluoresces green in ultraviolet light and it was also used for tinting and shading in early photography. The 1789 discovery of uranium in the mineral pitchblende is credited to Martin Heinrich Klaproth, eugène-Melchior Péligot was the first person to isolate the metal and its radioactive properties were discovered in 1896 by Henri Becquerel. An ensuing arms race during the Cold War between the United States and the Soviet Union produced tens of thousands of weapons that used uranium metal. The security of those weapons and their fissile material following the breakup of the Soviet Union in 1991 is a concern for public health. When refined, uranium is a white, weakly radioactive metal

Antimony
–
Antimony is a chemical element with symbol Sb and atomic number 51. A lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite, Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name, kohl. Metallic antimony was known, but it was erroneously identified as lead upon its discovery. In the West, it was first isolated by Vannoccio Biringuccio, for some time, China has been the largest producer of antimony and its compounds, with most production coming from the Xikuangshan Mine in Hunan. The industrial methods for refining antimony are roasting and reduction with carbon or direct reduction of stibnite with iron, the largest applications for metallic antimony is an alloy with lead and tin and the lead antimony plates in lead–acid batteries. Alloys of lead and tin with antimony have improved properties for solders, bullets, Antimony compounds are prominent additives for chlorine and bromine-containing fire retardants found in many commercial and domestic products. An emerging application is the use of antimony in microelectronics, Antimony is in a pnictogen and has an electronegativity of 2.05. In accordance with periodic trends, it is more electronegative than tin or bismuth, Antimony is stable in air at room temperature, but reacts with oxygen if heated to produce antimony trioxide, Sb2O3. Antimony is resistant to attack by acids, four allotropes of antimony are known, a stable metallic form and three metastable forms. Elemental antimony is a brittle, silver-white shiny metalloid, when slowly cooled, molten antimony crystallizes in a trigonal cell, isomorphic with the gray allotrope of arsenic. A rare explosive form of antimony can be formed from the electrolysis of antimony trichloride, when scratched with a sharp implement, an exothermic reaction occurs and white fumes are given off as metallic antimony forms, when rubbed with a pestle in a mortar, a strong detonation occurs. Black antimony is formed upon cooling of antimony vapor. It has the crystal structure as red phosphorus and black arsenic, it oxidizes in air. At 100 °C, it transforms into the stable form. The yellow allotrope of antimony is the most unstable and it has only been generated by oxidation of stibine at −90 °C. Above this temperature and in ambient light, this metastable allotrope transforms into the more stable black allotrope, elemental antimony adopts a layered structure in which layers consist of fused, ruffled, six-membered rings. The nearest and next-nearest neighbors form an octahedral complex, with the three atoms in each double layer slightly closer than the three atoms in the next. This relatively close packing leads to a density of 6.697 g/cm3

Arsenic
–
Arsenic is a chemical element with symbol As and atomic number 33. Arsenic occurs in minerals, usually in combination with sulfur and metals. It has various allotropes, but only the form is important to industry. The primary use of arsenic is in alloys of lead. Arsenic is a common dopant in semiconductor electronic devices. Arsenic and its compounds, especially the trioxide, are used in the production of pesticides, treated wood products, herbicides, a few species of bacteria are able to use arsenic compounds as respiratory metabolites. Trace quantities of arsenic are a dietary element in rats, hamsters, goats, chickens. However, arsenic poisoning occurs in multicellular life if quantities are larger than needed, Arsenic contamination of groundwater is a problem that affects millions of people across the world. The three most common allotropes are metallic gray, yellow, and black arsenic, with gray being the most common. Gray arsenic adopts a structure consisting of many interlocked, ruffled, six-membered rings. Because of weak bonding between the layers, gray arsenic is brittle and has a relatively low Mohs hardness of 3.5. Nearest and next-nearest neighbors form an octahedral complex, with the three atoms in the same double-layer being slightly closer than the three atoms in the next. This relatively close packing leads to a density of 5.73 g/cm3. Gray arsenic is a semimetal, but becomes a semiconductor with a bandgap of 1. 2–1.4 eV if amorphized, gray arsenic is also the most stable form. Yellow arsenic is soft and waxy, and somewhat similar to tetraphosphorus, both have four atoms arranged in a tetrahedral structure in which each atom is bound to each of the other three atoms by a single bond. This unstable allotrope, being molecular, is the most volatile, least dense, solid yellow arsenic is produced by rapid cooling of arsenic vapor, As 4. It is rapidly transformed into gray arsenic by light, the yellow form has a density of 1.97 g/cm3. Black arsenic is similar in structure to red phosphorus, black arsenic can also be formed by cooling vapor at around 100–220 °C

Potash
–
Potash /ˈpɒtæʃ/ is any of various mined and manufactured salts that contain potassium in water-soluble form. The name derives from pot ash, which refers to plant ashes soaked in water in a pot, the word potassium is derived from potash. Potash is produced worldwide at amounts exceeding 30 million tonnes per year, various types of fertilizer-potash thus constitute the single largest global industrial use of the element potassium. Potassium was first derived by electrolysis of caustic potash, in 1807, Potash refers to potassium compounds and potassium-bearing materials, the most common being potassium chloride. The term potash comes from the Middle Dutch word potaschen, approximately 10% by weight of common wood ash can be recovered as pot ash. Later, potash became the term applied to naturally occurring potassium salts. Potash ores are rich in potassium chloride and sodium chloride and are typically obtained by conventional shaft mining with the extracted ore ground into a powder. Other methods include dissolution mining and evaporation methods from brines, in the evaporation method hot water is injected into the potash which is dissolved and then pumped to the surface where it is concentrated by solar induced evaporation. Amine reagents are added to either the mined or evaporated solutions. The amine coats the KCl but not NaCl, air bubbles cling to the amine + KCl and float it to the surface while the NaCl and clay sink to the bottom. The surface is skimmed for the amine + KCl which is dried and packaged for use as a K rich fertilizer—KCl dissolves readily in water and is available quickly for plant nutrition. Potash deposits can be all over the world. At present deposits are being mined in Canada, Russia, China, Belarus, Israel, Germany, Chile, the United States, Jordan, Spain, Potash has been used in bleaching textiles, making glass, and making soap, since about AD500. Potash was principally obtained by leaching the ashes of land and sea plants, beginning in the 14th century potash was mined in Ethiopia. One of the worlds largest deposits,140 to 150 million tons, is located in the Tigrays Dallol area, Potash was one of the most important industrial chemicals in Canada. It was refined from the ashes of broadleaved trees and produced primarily in the areas of Europe, Russia. The first U. S. patent of any kind was issued in 1790 to Samuel Hopkins for an improvement in the making of Pot ash and Pearl ash by a new Apparatus, Pearl ash was a purer quality made by the ignition of cream of tartar. Potash pits were used in England to produce potash that was used in making soap for the preparation of wool for yarn production

Feldspar
–
Feldspars are a group of rock-forming tectosilicate minerals that make up about 40% of the Earths continental crust. Feldspars crystallize from magma as veins in both intrusive and extrusive rocks and are also present in many types of metamorphic rock. Rock formed almost entirely of plagioclase feldspar is known as anorthosite. Feldspars are also found in types of sedimentary rocks. The name feldspar derives from the German Feldspat, a compound of the words Feld, field, and Spat, the change from Spat to -spar was influenced by the English word spar, a synonym for mineral. Feldspathic refers to materials that contain feldspar, the alternate spelling, felspar, has largely fallen out of use. This group of minerals consists of tectosilicates, solid solutions between albite and anorthite are called plagioclase, or more properly plagioclase feldspar. Only limited solid solution occurs between K-feldspar and anorthite, and in the two solid solutions, immiscibility occurs at temperatures common in the crust of the earth. Albite is considered both a plagioclase and alkali feldspar, the alkali feldspars are as follows, orthoclase —KAlSi3O8 sanidine —AlSi3O8 microcline —KAlSi3O8 anorthoclase —AlSi3O8 Sanidine is stable at the highest temperatures, and microcline at the lowest. Perthite is a texture in alkali feldspar, due to exsolution of contrasting alkali feldspar compositions during cooling of an intermediate composition. The perthitic textures in the alkali feldspars of many granites can be seen with the naked eye, microperthitic textures in crystals are visible using a light microscope, whereas cryptoperthitic textures can be seen only with an electron microscope. Barium feldspars are also considered alkali feldspars, barium feldspars form as the result of the substitution of barium for potassium in the mineral structure. The barium feldspars are monoclinic and include the following, celsian—BaAl2Si2O8 hyalophane—4O8 The plagioclase feldspars are triclinic, the immiscibility gaps in the plagioclase solid solutions are complex compared to the gap in the alkali feldspars. The play of colours visible in some feldspar of labradorite composition is due to very fine-grained exsolution lamellae, chemical weathering of feldspars results in the formation of clay minerals. About 20 million tonnes of feldspar were produced in 2010, mostly by three countries, Italy, Turkey, and China, Feldspar is a common raw material used in glassmaking, ceramics, and to some extent as a filler and extender in paint, plastics, and rubber. In glassmaking, alumina from feldspar improves product hardness, durability, in ceramics, the alkalis in feldspar act as a flux, lowering the melting temperature of a mixture. Fluxes melt at a stage in the firing process, forming a glassy matrix that bonds the other components of the system together. In the US, about 66% of feldspar is consumed in glassmaking, including glass containers, ceramics and other uses, such as fillers, accounted for the remainder

Fluorspar
–
Fluorite is the mineral form of calcium fluoride, CaF2. It belongs to the halide minerals and it crystallizes in isometric cubic habit, although octahedral and more complex isometric forms are not uncommon. Mohs scale of hardness, based on scratch Hardness comparison. Fluorite is a mineral, both in visible and ultraviolet light, and the stone has ornamental and lapidary uses. Industrially, fluorite is used as a flux for smelting, and in the production of certain glasses, the purest grades of fluorite are a source of fluoride for hydrofluoric acid manufacture, which is the intermediate source of most fluorine-containing fine chemicals. Optically clear transparent fluorite lenses have low dispersion, so made from it exhibit less chromatic aberration. Fluorite optics are also usable in the range, where conventional glasses are too absorbent for use. The word fluorite is derived from the Latin verb fluere, meaning to flow, the mineral is used as a flux in iron smelting to decrease the viscosity of slags. The term flux comes from the Latin adjective fluxus, meaning flowing, loose, agricola, a German scientist with expertise in philology, mining, and metallurgy, named fluorspar as a neo-Latinization of the German Flussspat from Fluß and Spat. In 1852, fluorite gave its name to the phenomenon of fluorescence, Fluorite also gave the name to its constitutive element fluorine. Presently, the fluorspar is most commonly used for fluorite as the industrial and chemical commodity, while fluorite is used mineralogically. Fluorite crystallises in a cubic motif, crystal twinning is common and adds complexity to the observed crystal habits. Fluorite has four perfect cleavage planes that help produce octahedral fragments, element substitution for the calcium cation often includes certain rare earth elements, such as yttrium and cerium. Iron, sodium, and barium are also common impurities, some fluorine may be replaced by the chloride anion. Fluorite is a widely occurring mineral that occurs globally with significant deposits in over 9,000 areas. It may occur as a deposit, especially with metallic minerals, where it often forms a part of the gangue and may be associated with galena, sphalerite, barite, quartz. It is a mineral in deposits of hydrothermal origin and has been noted as a primary mineral in granites and other igneous rocks. The world reserves of fluorite are estimated at 230 million tonnes with the largest deposits being in South Africa, Mexico, China is leading the world production with about 3 Mt annually, followed by Mexico, Mongolia, Russia, South Africa, Spain and Namibia

Gypsum
–
Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO4·2H2O. It is widely mined and is used as a fertilizer, and as the constituent in many forms of plaster, blackboard chalk. Mohs scale of hardness, based on scratch Hardness comparison. It forms as a mineral and as a hydration product of anhydrite. The word gypsum is derived from the Greek word γύψος, plaster, because the quarries of the Montmartre district of Paris have long furnished burnt gypsum used for various purposes, this dehydrated gypsum became known as plaster of Paris. Upon addition of water, after a few tens of minutes plaster of Paris becomes regular gypsum again, causing the material to harden or set in ways that are useful for casting, Gypsum was known in Old English as spærstān, spear stone, referring to its crystalline projections. Gypsum may act as a source of sulfur for plant growth, which was discovered by J. M. Mayer, american farmers were so anxious to acquire it that a lively smuggling trade with Nova Scotia evolved, resulting in the so-called Plaster War of 1820. In the 19th century, it was known as lime sulfate or sulfate of lime. Gypsum is moderately water-soluble and, in contrast to most other salts, it exhibits retrograde solubility, when gypsum is heated in air it loses water and converts first to calcium sulfate hemihydrate, and, if heated further, to anhydrous calcium sulfate. As for anhydrite, its solubility in saline solutions and in brines is also dependent on NaCl concentration. Gypsum crystals are found to contain water and hydrogen bonding. Gypsum occurs in nature as flattened and often twinned crystals, and transparent, selenite contains no significant selenium, rather, both substances were named for the ancient Greek word for the Moon. Selenite may also occur in a silky, fibrous form, in case it is commonly called satin spar. Finally, it may also be granular or quite compact, in hand-sized samples, it can be anywhere from transparent to opaque. A very fine-grained white or lightly tinted variety of gypsum, called alabaster, is prized for ornamental work of various sorts, in arid areas, gypsum can occur in a flower-like form, typically opaque, with embedded sand grains called desert rose. It also forms some of the largest crystals found in nature, up to 12 m long, Gypsum is a common mineral, with thick and extensive evaporite beds in association with sedimentary rocks. Deposits are known to occur in strata from as far back as the Archaean eon, Gypsum is deposited from lake and sea water, as well as in hot springs, from volcanic vapors, and sulfate solutions in veins. Hydrothermal anhydrite in veins is commonly hydrated to gypsum by groundwater in near-surface exposures and it is often associated with the minerals halite and sulfur

Timber
–
Lumber, or timber is wood that has been processed into beams and planks, a stage in the process of wood production. Lumber may also refer to currently un-needed furniture, as in Lumber room, or an awkward gait, ultimately derived from the look of unfashionable, Lumber may be supplied either rough-sawn, or surfaced on one or more of its faces. Besides pulpwood, rough lumber is the raw material for furniture-making and it is available in many species, usually hardwoods, but it is also readily available in softwoods, such as white pine and red pine, because of their low cost. Lumber is mainly used for structural purposes but has other uses as well. It is classified more commonly as a softwood than as a hardwood, in Australia, Ireland, New Zealand and Britain, the term timber describes sawn wood products, such as floor boards. In the United States and Canada, generally timber describes standing or felled trees, before they are milled into boards, Timber there also describes sawn lumber not less than 5 inches in its smallest dimension. The latter includes the often partly finished lumber used in timber-frame construction, remanufactured lumber is the result of secondary or tertiary processing/cutting of previously milled lumber. Specifically, it is cut for industrial or wood-packaging use. Lumber is cut by ripsaw or resaw to create dimensions that are not usually processed by a primary sawmill, resawing is the splitting of 1-inch through 12-inch hardwood or softwood lumber into two or more thinner pieces of full-length boards. For example, splitting a ten-foot 2×4 into two ten-foot 1×4s is considered resawing, structural lumber may also be produced from recycled plastic and new plastic stock. Its introduction has been opposed by the forestry industry. Blending fiberglass in plastic lumber enhances its strength, durability, logs are converted into timber by being sawn, hewn, or split. Sawing with a rip saw is the most common method, because sawing allows logs of lower quality, with grain and large knots. There are various types of sawing, Plain sawn —A log sawn through without adjusting the position of the log, quarter sawn and rift sawn—These terms have been confused in history but generally mean lumber sawn so the annual rings are reasonably perpendicular to the sides of the lumber. Boxed heart—The pith remains within the piece with some allowance for exposure, heart center—the center core of a log. Free of heart center —A side-cut timber without any pith, free of knots —No knots are present. Dimensional lumber is lumber that is cut to standardized width and depth, carpenters extensively use dimensional lumber in framing wooden buildings. Common sizes include 2×4, 2×6, and 4×4, the length of a board is usually specified separately from the width and depth

Fish
–
A fish is any member of a group of animals that consist of all gill-bearing aquatic craniate animals that lack limbs with digits. They form a group to the tunicates, together forming the olfactores. Included in this definition are the living hagfish, lampreys, and cartilaginous, tetrapods emerged within lobe-finned fishes, so cladistically they are fish as well. However, traditionally fish are rendered obsolete or paraphyletic by excluding the tetrapods, because in this manner the term fish is defined negatively as a paraphyletic group, it is not considered a formal taxonomic grouping in systematic biology. The traditional term pisces is considered a typological, but not a phylogenetic classification, the earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts, fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators, the first fish with jaws appeared in the Silurian period, after which many became formidable marine predators rather than just the prey of arthropods. Fish are abundant in most bodies of water and they can be found in nearly all aquatic environments, from high mountain streams to the abyssal and even hadal depths of the deepest oceans. With 33,100 described species, fish exhibit greater species diversity than any group of vertebrates. Fish are an important resource for humans worldwide, especially as food, commercial and subsistence fishers hunt fish in wild fisheries or farm them in ponds or in cages in the ocean. They are also caught by fishers, kept as pets, raised by fishkeepers. Fish have had a role in culture through the ages, serving as deities, religious symbols, fish do not represent a monophyletic group, and therefore the evolution of fish is not studied as a single event. Early fish from the record are represented by a group of small, jawless. Jawless fish lineages are mostly extinct, an extant clade, the lampreys may approximate ancient pre-jawed fish. The first jaws are found in Placodermi fossils, the diversity of jawed vertebrates may indicate the evolutionary advantage of a jawed mouth. It is unclear if the advantage of a hinged jaw is greater biting force, improved respiration, fish may have evolved from a creature similar to a coral-like sea squirt, whose larvae resemble primitive fish in important ways. The first ancestors of fish may have kept the form into adulthood. Fish are a group, that is, any clade containing all fish also contains the tetrapods

Gold
–
Gold is a chemical element with symbol Au and atomic number 79. In its purest form, it is a bright, slightly yellow, dense, soft, malleable. Chemically, gold is a metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions, Gold often occurs in free elemental form, as nuggets or grains, in rocks, in veins, and in alluvial deposits. It occurs in a solid solution series with the element silver and also naturally alloyed with copper. Less commonly, it occurs in minerals as gold compounds, often with tellurium, golds atomic number of 79 makes it one of the higher numbered, naturally occurring elements. It is thought to have produced in supernova nucleosynthesis, from the collision of neutron stars. Because the Earth was molten when it was formed, almost all of the present in the early Earth probably sank into the planetary core. Gold is resistant to most acids, though it does dissolve in aqua regia, a mixture of acid and hydrochloric acid. Gold also dissolves in solutions of cyanide, which are used in mining and electroplating. Gold dissolves in mercury, forming amalgam alloys, but this is not a chemical reaction, as a precious metal, gold has been used for coinage, jewelry, and other arts throughout recorded history. A total of 186,700 tonnes of gold is in existence above ground, the world consumption of new gold produced is about 50% in jewelry, 40% in investments, and 10% in industry. Gold is also used in infrared shielding, colored-glass production, gold leafing, certain gold salts are still used as anti-inflammatories in medicine. As of 2014, the worlds largest gold producer by far was China with 450 tonnes, Gold is cognate with similar words in many Germanic languages, deriving via Proto-Germanic *gulþą from Proto-Indo-European *ǵʰelh₃-. The symbol Au is from the Latin, aurum, the Latin word for gold, the Proto-Indo-European ancestor of aurum was *h₂é-h₂us-o-, meaning glow. This word is derived from the root as *h₂éu̯sōs, the ancestor of the Latin word Aurora. This etymological relationship is presumably behind the frequent claim in scientific publications that aurum meant shining dawn, Gold is the most malleable of all metals, a single gram can be beaten into a sheet of 1 square meter, and an avoirdupois ounce into 300 square feet. Gold leaf can be thin enough to become semi-transparent
21.
Avalanche
–
An avalanche is a rapid flow of snow down a sloping surface. Avalanches are typically triggered in a zone from a mechanical failure in the snowpack when the forces on the snow exceed its strength. After initiation, avalanches usually accelerate rapidly and grow in mass, if the avalanche moves fast enough some of the snow may mix with the air forming a powder snow avalanche, which is a type of gravity current. Slides of rocks or debris, behaving in a way to snow, are also referred to as avalanches. The remainder of this article refers to snow avalanches, the load on the snowpack may be only due to gravity, in which case failure may result either from weakening in the snowpack or increased load due to precipitation. Avalanches that occur in this way are known as spontaneous avalanches, Avalanches can also be triggered by other loads such as skiers, snowmobilers, animals or explosives. Seismic activity may trigger the failure in the snowpack and avalanches. A popular myth is that avalanches can be triggered by loud noise or shouting, Avalanches are not rare or random events and are endemic to any mountain range that accumulates a standing snowpack. Avalanches are most common during winter or spring but glacier movements may cause ice, there is no universally accepted classification of avalanches—different classifications are useful for different purposes. Avalanches can be described by their size, their potential, their initiation mechanism, their composition. Most avalanches occur spontaneously during storms under increased load due to snowfall, the second largest cause of natural avalanches is metamorphic changes in the snowpack such as melting due to solar radiation. Other natural causes include rain, earthquakes, rockfall and icefall, artificial triggers of avalanches include skiers, snowmobiles, and controlled explosive work. Avalanche initiation can start at a point with only an amount of snow moving initially. A snowpack will fail when the load exceeds the strength, the load is straightforward, it is the weight of the snow. However, the strength of the snowpack is much more difficult to determine and is extremely heterogenous and it varies in detail with properties of the snow grains, size, density, morphology, temperature, water content, and the properties of the bonds between the grains. These properties may all metamorphose in time according to the humidity, water vapour flux, temperature. The top of the snowpack is also influenced by incoming radiation. One of the aims of research is to develop and validate computer models that can describe the evolution of the seasonal snowpack over time
22.
Drought
–
A drought is a period of below-average precipitation in a given region, resulting in prolonged shortages in its water supply, whether atmospheric, surface water or ground water. A drought can last for months or years, or may be declared after as few as 15 days and it can have a substantial impact on the ecosystem and agriculture of the affected region and harm to the local economy. Annual dry seasons in the tropics significantly increase the chances of a drought developing, periods of heat can significantly worsen drought conditions by hastening evaporation of water vapour. Many plant species, such as those in the family Cactaceae, have drought tolerance adaptations like reduced leaf area, some others survive dry periods as buried seeds. Semi-permanent drought produces arid biomes such as deserts and grasslands, prolonged droughts have caused mass migrations and humanitarian crises. Most arid ecosystems have inherently low productivity, the most prolonged drought ever in the world in recorded history occurred in the Atacama Desert in Chile. Mechanisms of producing precipitation include convective, stratiform, and orographic rainfall, precipitation can be divided into three categories, based on whether it falls as liquid water, liquid water that freezes on contact with the surface, or ice. Drought are mainly course by in low rain areas, if these factors do not support precipitation volumes sufficient to reach the surface over a sufficient time, the result is a drought. Once a region is within drought, feedback mechanisms such as local arid air, hot conditions which can promote warm core ridging, within the tropics, distinct, wet and dry seasons emerge due to the movement of the Intertropical Convergence Zone or Monsoon trough. The dry season greatly increases drought occurrence, and is characterized by its low humidity, with watering holes, because of the lack of these watering holes, many grazing animals are forced to migrate due to the lack of water and feed to more fertile spots. Examples of such animals are zebras, elephants, and wildebeest, because of the lack of water in the plants, bushfires are common. Since water vapor becomes more energetic with increasing temperature, more water vapor is required to increase relative humidity values to 100% at higher temperatures, periods of warmth quicken the pace of fruit and vegetable production, increase evaporation and transpiration from plants, and worsen drought conditions. Drier and hotter weather occurs in parts of the Amazon River Basin, Colombia, winters during the El Niño are warmer and drier than average conditions in the Northwest, northern Midwest, and northern Mideast United States, so those regions experience reduced snowfalls. Conditions are also drier than normal from December to February in south-central Africa, mainly in Zambia, Zimbabwe, Mozambique, and Botswana. Direct effects of El Niño resulting in drier conditions occur in parts of Southeast Asia and Northern Australia, increasing bush fires, worsening haze, drier-than-normal conditions are also in general observed in Queensland, inland Victoria, inland New South Wales, and eastern Tasmania from June to August. As warm water spreads from the west Pacific and the Indian Ocean to the east Pacific, it causes extensive drought in the western Pacific. Singapore experienced the driest February in 2014 since records began in 1869, with only 6.3 mm of rain falling in the month, the years 1968 and 2005 had the next driest Februaries, when 8.4 mm of rain fell. Human activity can directly trigger exacerbating factors such as farming, excessive irrigation, deforestation

Forest fire
–
A wildfire or wildland fire is a fire in an area of combustible vegetation that occurs in the countryside or rural area. Fossil charcoal indicates that wildfires began soon after the appearance of terrestrial plants 420 million years ago, wildfire’s occurrence throughout the history of terrestrial life invites conjecture that fire must have had pronounced evolutionary effects on most ecosystems flora and fauna. Earth is an intrinsically flammable planet owing to its cover of vegetation, seasonally dry climates, atmospheric oxygen. Wildfires can be characterized in terms of the cause of ignition, their properties, the combustible material present. Wildfires can cause damage to property and human life, but they have beneficial effects on native vegetation, animals. Many plant species depend on the effects of fire for growth, however, wildfire in ecosystems where wildfire is uncommon or where non-native vegetation has encroached may have negative ecological effects. Wildfire behaviour and severity result from the combination of such as available fuels, physical setting. Strategies of wildfire prevention, detection, and suppression have varied over the years, one common and inexpensive technique is controlled burning, permitting or even igniting smaller fires to minimize the amount of flammable material available for a potential wildfire. Vegetation may be burned periodically to maintain species diversity and frequent burning of surface fuels limits fuel accumulation. Wildland fire use is the cheapest and most ecologically appropriate policy for many forests, fuels may also be removed by logging, but fuels treatments and thinning have no effect on severe fire behavior. Wildfires can also be started in communities experiencing shifting cultivation, where land is cleared quickly and farmed until the soil loses fertility, forested areas cleared by logging encourage the dominance of flammable grasses, and abandoned logging roads overgrown by vegetation may act as fire corridors. The most common cause of wildfires throughout the world. In Canada and northwest China, for example, lightning operates as the source of ignition. In other parts of the world, human involvement is a major contributor, in China and in the Mediterranean Basin, human carelessness is a major cause of wildfires. In the United States and Australia, the source of wildfires can be traced both to lightning strikes and to human activities. Coal seam fires burn in the thousands around the world, such as those in Burning Mountain, New South Wales, Centralia, Pennsylvania and they can also flare up unexpectedly and ignite nearby flammable material. The spread of wildfires based on the flammable material present, its vertical arrangement and moisture content. Fuel arrangement and density is governed in part by topography, as land shape determines factors such as available sunlight, overall, fire types can be generally characterized by their fuels as follows, Ground fires are fed by subterranean roots, duff and other buried organic matter
24.
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 deforestationinclude conversion of forestland to farms, ranches, or urban use, 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. 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. Tropical deforestation is responsible for approximately 20% of world greenhouse gas emissions, according to the Intergovernmental Panel on Climate Change deforestation, mainly in tropical areas, could account for up to one-third of total anthropogenic carbon dioxide emissions

Sedimentary rock
–
Sedimentary rocks are types of rock that are formed by the deposition and subsequent cementation of that material at the Earths surface and within bodies of water. Sedimentation is the name for processes that cause mineral and/or organic particles to settle in place. The particles that form a rock by accumulating are called sediment. Sedimentation may also occur as minerals precipitate from solution or shells of aquatic creatures settle out of suspension. The sedimentary rock cover of the continents of the Earths crust is extensive, sedimentary rocks are only a thin veneer over a crust consisting mainly of igneous and metamorphic rocks. Sedimentary rocks are deposited in layers as strata, forming a structure called bedding, sedimentary rocks are also important sources of natural resources like coal, fossil fuels, drinking water or ores. The study of the sequence of rock strata is the main source for an understanding of the Earths history, including palaeogeography, paleoclimatology. The scientific discipline that studies the properties and origin of rocks is called sedimentology. Sedimentology is part of both geology and physical geography and overlaps partly with other disciplines in the Earth sciences, such as pedology, geomorphology, geochemistry, sedimentary rocks have also been found on Mars. Clastic sedimentary rocks are composed of rock fragments that were cemented by silicate minerals. Clastic rocks are composed largely of quartz, feldspar, rock fragments, clay minerals, and mica, any type of mineral may be present, clastic sedimentary rocks, are subdivided according to the dominant particle size. Most geologists use the Udden-Wentworth grain size scale and divide unconsolidated sediment into three fractions, gravel, sand, and mud and this tripartite subdivision is mirrored by the broad categories of rudites, arenites, and lutites, respectively, in older literature. The subdivision of these three categories is based on differences in clast shape, conglomerates and breccias), composition. Conglomerates are dominantly composed of rounded gravel, while breccias are composed of dominantly angular gravel, composition of framework grains The relative abundance of sand-sized framework grains determines the first word in a sandstone name. Naming depends on the dominance of the three most abundant components quartz, feldspar, or the lithic fragments that originated from other rocks, all other minerals are considered accessories and not used in the naming of the rock, regardless of abundance. Clean sandstones with open space are called arenites. Muddy sandstones with abundant muddy matrix are called wackes, six sandstone names are possible using the descriptors for grain composition and the amount of matrix. Mudrocks are sedimentary rocks composed of at least 50% silt- and clay-sized particles and these relatively fine-grained particles are commonly transported by turbulent flow in water or air, and deposited as the flow calms and the particles settle out of suspension

Normandy
–
Normandy is one of the regions of France, roughly corresponding to the historical Duchy of Normandy. Administratively, Normandy is divided into five departments, Calvados, Eure, Manche, Orne and it covers 30,627 km², forming roughly 5% of the territory of France. Its population of 3.37 million accounts for around 5% of the population of France, Normans is the name given to the inhabitants of Normandy, and the region is the homeland of the Norman language. The historical region of Normandy comprised the region of Normandy, as well as small areas now part of the départements, or departments of Mayenne. For a century and a following the Norman conquest of England in 1066, Normandy and England were linked by Norman. Archaeological finds, such as paintings, prove that humans were present in the region in prehistoric times. Celts invaded Normandy in successive waves from the 4th to the 3rd century BC, when Julius Caesar invaded Gaul, there were nine different Celtic tribes living in Normandy. The Romanisation of Normandy was achieved by the methods, Roman roads. Classicists have knowledge of many Gallo-Roman villas in Normandy, in the late 3rd century, barbarian raids devastated Normandy. Coastal settlements were raided by Saxon pirates, Christianity also began to enter the area during this period. In 406, Germanic tribes began invading from the east, while the Saxons subjugated the Norman coast, the Roman Emperor withdrew from most of Normandy. As early as 487, the area between the River Somme and the River Loire came under the control of the Frankish lord Clovis, the Vikings started to raid the Seine Valley during the middle of the 9th century. As early as 841, a Viking fleet appeared at the mouth of the Seine, after attacking and destroying monasteries, including one at Jumièges, they took advantage of the power vacuum created by the disintegration of Charlemagnes empire to take northern France. The fiefdom of Normandy was created for the Norwegian Viking leader Hrólfr Ragnvaldsson, Rollo had besieged Paris but in 911 entered vassalage to the king of the West Franks, Charles the Simple, through the Treaty of Saint-Clair-sur-Epte. In exchange for his homage and fealty, Rollo legally gained the territory which he, the name Normandy reflects Rollos Viking origins. The descendants of Rollo and his followers adopted the local Gallo-Romance language and they became the Normans – a Norman-speaking mixture of Saxons and indigenous Franks and Celts. Besides the Norman conquest of England and the subsequent conquests of Wales and Ireland, Norman families, such as that of Tancred of Hauteville, Rainulf Drengot and Guimond de Moulins played important parts in the Norman conquest of southern Italy and Crusades. They also carved out a place for themselves and their descendants in the Crusader states of Asia Minor, the 14th century Norman explorer Jean de Béthencourt established a kingdom in the Canary Islands

Brittany (administrative region)
–
Brittany is one of the 18 regions of France. It is named after the historic and geographic region of Brittany, the region of Brittany was created in 1941 on 80% of the territory of traditional Brittany. The remaining 20% is now called the Loire-Atlantique department which is included in the Pays de la Loire region, whose capital, part of the reason why Brittany was split between two present-day regions was to avoid the rivalry between Rennes and Nantes. Although Nantes was the capital of the Duchy of Brittany until the sixteenth century. Despite that, the Chambre des comptes had remained in Nantes until 1789, although there were previous plans to create Régions out of the Départements, like the Clémentel plan or the Vichy regionalisation programme, these plans had no effect or else were abolished in 1945. The current French Regions date from 1956 and were created by gathering Departements together, in Brittany, this led to the creation of the new Region of Brittany, which included only four out of the five historical Breton départements. The term region was created by the Law of Decentralisation. The first direct elections for representatives took place on 16 March 1986. See History of Brittany Brittany, lying in the northwest corner of France, is one of the historic provinces of France. The most Atlantic of Frances regions, Brittany is proud of its Celtic heritage and it enjoys a mild climate somewhat warmer though not necessarily drier than the climate of the southwest of England. Quimper, the capital of the Finistère, and St. Brieuc and it is also the venue for Brittanys annual Interceltiques music and culture festival. Despite its limited size, Brittany is quite a diverse region, the south coast, facing onto the Bay of Biscay, is flatter, much milder, and graced by a number of large sandy beaches. The sea here is warmer in summer, the backbone of Brittany is a granite ridge stretching from east to west, peaking in the Monts dArrée. But most of inland Brittany is gentle farming country, a famous for its milk and butter. In cultural terms, Brittany is very distinctive, with its own language and Celtic cultural tradition that set it apart from the rest of France. The Breton language, though not much used in life, and not understood by most of the modern population, has made a comeback in recent years. Celtic traditions are alive or recalled today in Breton folk music, its Celtic festivals, the name of Brittany derives from settlers from Great Britain, who fled that island in the wake of the Anglo-Saxon conquest of England between the fifth and seventh centuries. Unlike the rest of France and Brittany, Lower Brittany has maintained a distinctly Celtic language, Breton and it was the dominant language in Lower, or western, Brittany until the mid-20th century

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

Administrative divisions of France
–
The administrative divisions of France are concerned with the institutional and territorial organization of French territory. There are many divisions, which may have political, electoral. The French republic is divided into 18 regions,13 in metropolitan France and 5 in overseas France, the regions are subdivided into 96 departments. The departments are subdivided into 322 arrondissements, the arrondissements are subdivided into 1,995 cantons. The cantons are subdivided into 36,529 communes, three urban communes are further divided into municipal arrondissements. There are 20 arrondissements of Paris,16 arrondissements of Marseille, the city of Marseilles is also divided into 8 municipal sectors. Each sector is composed with two arrondissements. 4% of the population of metropolitan France living in them, each overseas region is coextensive with an overseas department, again with the same status as departments in metropolitan France. The first four departments were created in 1946 and preceded the four overseas regions. For elections it is divided into 6 electoral districts which differ slightly from the 5 administrative subdivisions, the 5 administrative subdivisions are divided into 48 communes. There also exist some associated communes as in metropolitan France, Saint-Barthélemy is a new overseas collectivity created on February 22,2007. It was previously a commune inside the Guadeloupe department, the commune structure was abolished and Saint-Barthélemy is now one of only three permanently inhabited territories of the French Republic with no commune structure. There are no cantons and arrondissements either, Saint-Martin is also a new overseas collectivity created on February 22,2007. It was also previously a commune inside the Guadeloupe department, the commune structure was abolished and Saint-Martin is now one of only three permanently inhabited territories of the French Republic with no commune structure. There are no cantons and arrondissements either, saint-Pierre and Miquelon is divided into 2 communes with no arrondissements or cantons. These 3 districts are, Uvea, Sigave, and Alo, Uvea is the most populous and is further divided into 3 wards, Hahake, Mua, and Hihifo. Wallis and Futuna is one of only three permanently inhabited territories of the French Republic with no communes and it also has no arrondissements or cantons. 1 overseas territory, the French Southern and Antarctic Lands, which have no permanent population, the French Southern and Antarctic Lands are divided into 5 districts,1. Amsterdam Island and Saint Paul Island 4, the Scattered Islands, a collection of six non permanently inhabited islands in the Indian Ocean, Banc du Geyser, Bassas da India, Europa, Juan de Nova, Glorioso, and Tromelin

Corsica
–
Corsica is an island in the Mediterranean Sea and one of the 13 regions of France. It is located west of the Italian Peninsula, southeast of the French mainland, a single chain of mountains make up two-thirds of the island. While being part of France, Corsica is also designated as a territorial collectivity by law, as a territorial collectivity, Corsica enjoys a greater degree of autonomy than other French regions, for example, the Corsican Assembly is able to exercise limited executive powers. The island formed a single department until it was split in 1975 into two departments, Haute-Corse and Corse-du-Sud, with its capital in Ajaccio, the prefecture city of Corse-du-Sud. Bastia, the city of Haute-Corse, is the second-largest settlement in Corsica. After being ruled by the Republic of Genoa since 1284, Corsica was briefly an independent Corsican Republic from 1755 until it was conquered by France in 1769. Due to Corsicas historical ties with the Italian peninsula, the island retains to this day many elements of the culture of Italy, the native Corsican language, whose northern variant is closely related to the Italian language, is recognised as a regional language by the French government. This Mediterranean island was ruled by various nations over the course of history but had several periods of independence. Napoleon was born in 1769 in the Corsican capital of Ajaccio and his ancestral home, Maison Bonaparte, is today used as a museum. The origin of the name Corsica is subject to much debate, to the Ancient Greeks it was known as Kalliste, Corsis, Cyrnos, Cernealis, or Cirné. Of these Cyrnos, Cernealis, or Cirné derive from a corruption of the most ancient Greek name of the island, Σειρηνούσσαι, the claim that latter Greek names are based on the Phoenician word for peninsula are highly unlikely. Corsica has been occupied continuously since the Mesolithic era and it acquired an indigenous population that was influential in the Mediterranean during its long prehistory. The Romans, who built a colony in Aléria, considered Corsica as one of the most backward regions of the Roman world, the island produced sheep, honey, resin and wax, and exported many slaves, not well considered because of their fierce and rebellious character. Moreover, it was known for its wines, exported to Rome. Administratively, the island was divided in pagi, which in the Middle Ages became the pievi, Corsica was integrated by Emperor Diocletian in Roman Italy. In the 5th century, the half of the Roman Empire collapsed, and the island was invaded by the Vandals. Briefly recovered by the Byzantines, it became part of the Kingdom of the Lombards—this made it a dependency of the March of Tuscany. Pepin the Short, king of the Franks and Charlemagnes father, expelled the Lombards, in the first quarter of the 11th century, Pisa and Genoa together freed the island from the threat of Arab invasion

Communes of France
–
The commune is a level of administrative division in the French Republic. French communes are roughly equivalent to civil townships incorporated municipalities in the United States or Gemeinden in Germany, the United Kingdom has no exact equivalent, as communes resemble districts in urban areas, but are closer to parishes in rural areas where districts are much larger. Communes are based on historical geographic communities or villages and have received significant powers of governance to manage the populations, the communes are the fourth-level administrative divisions of France. A French commune may be a city of 2.2 million inhabitants like Paris, communes typically are based on pre-existing villages and facilitate local governance. All communes have names, but not all named geographic areas or groups of people residing together are communes, a commune is a town, city, or municipality. Use of commune in English is a habit, and one that might be corrected. There is nothing in commune in French that is different from town in English. The French word commune appeared in the 12th century, from Medieval Latin communia, as of January 2015, there were 36,681 communes in France,36,552 of them in metropolitan France and 129 of them overseas. This is a higher total than that of any other European country. The whole territory of the French Republic is divided into communes and this is unlike some other countries, such as the United States, where unincorporated areas directly governed by a county or a higher authority can be found. There are only a few exceptions, COM of Saint-Martin and it was previously a commune inside the Guadeloupe région. The commune structure was abolished when Saint-Martin became an overseas collectivity on 22 February 2007, COM of Wallis and Futuna, which still is divided according to the three traditional chiefdoms. It was previously a commune inside the Guadeloupe region, the commune structure was abolished when Saint-Barthélemy became an overseas collectivity on 22 February 2007.88 square kilometres. The median area of metropolitan Frances communes at the 1999 census was even smaller, the median area is a better measure of the area of a typical French commune. This median area is smaller than that of most European countries. In Italy, the area of communes is 22 km2, in Belgium it is 40 km2, in Spain it is 35 km2, and in Germany. Switzerland and the Länder of Rhineland-Palatinate, Schleswig-Holstein, and Thuringia in Germany were the places in Europe where the communes had a smaller median area than in France. The communes of Frances overseas départements such as Réunion and French Guiana are large by French standards and they usually group into the same commune several villages or towns, often with sizeable distances among them

Scale (map)
–
The scale of a map is the ratio of a distance on the map to the corresponding distance on the ground. This simple concept is complicated by the curvature of the Earths surface, because of this variation, the concept of scale becomes meaningful in two distinct ways. The first way is the ratio of the size of the globe to the size of the Earth. The generating globe is a model to which the Earth is shrunk. The ratio of the Earths size to the generating globes size is called the nominal scale, many maps state the nominal scale and may even display a bar scale to represent it. The second distinct concept of scale applies to the variation in scale across a map and it is the ratio of the mapped points scale to the nominal scale. In this case means the scale factor. If the region of the map is small enough to ignore Earths curvature—a town plan, in maps covering larger areas, or the whole Earth, the maps scale may be less useful or even useless in measuring distances. The map projection becomes critical in understanding how scale varies throughout the map, when scale varies noticeably, it can be accounted for as the scale factor. Tissots indicatrix is often used to illustrate the variation of point scale across a map, map scales may be expressed in words, as a ratio, or as a fraction. Examples are, one centimetre to one hundred metres or 1,10,000 or 1/10,000 one inch to one mile or 1,63,360 or 1/63,360 one centimetre to one thousand kilometres or 1,100,000,000 or 1/100,000,000. In addition to the many maps carry one or more bar scales. For example, some modern British maps have three bar scales, one each for kilometres, miles and nautical miles, a lexical scale may cause problems if it expressed in a language that the user does not understand or in obsolete or ill-defined units. For example, a scale of one inch to a furlong will be understood by older people in countries where Imperial units used to be taught in schools. A map is classified as small scale or large scale or sometimes medium scale, small scale refers to world maps or maps of large regions such as continents or large nations. In other words, they show areas of land on a small space. They are called small scale because the fraction is relatively small. Large scale maps show areas in more detail, such as county maps or town plans might

French Guiana
–
French Guiana, officially called Guiana, is an overseas department and region of France, located on the north Atlantic coast of South America in the Guyanas. It borders Brazil to the east and south, and Suriname to the west. Its 83,534 km2 area has a low population density of only 3 inhabitants per km2, with half of its 244,118 inhabitants in 2013 living in the metropolitan area of Cayenne. By land area, it is the second largest region of France, both the region and the department have been ruled since December 2015 by a single assembly within the framework of a new territorial collectivity, the French Guiana Territorial Collectivity. This assembly, the French Guiana Assembly, has replaced the regional council and departmental council. The French Guiana Assembly is in charge of regional and departmental government, the area was originally inhabited by Native Americans. The first French establishment is recorded in 1503 but the French presence didnt really become durable until 1643, Guiana then became a slave colony and saw its population increase until the official abolition of slavery at the time of the French revolution. During World War II, the Guianan Félix Éboué was one of the first to stand behind General de Gaulle as early as June 18,1940, Guiana officially rallied Free France in 1943. It definitively abandoned its status as a colony and became again a French department in 1946, de Gaulle, who became president, decided to establish the Guiana Space Center in 1965. It is now operated by the CNES, Arianespace and the European Space Agency, several thousand Hmong refugees from Laos migrated to French Guiana in the late 1970s and early 1980s. Nowadays fully integrated in the French central state, Guiana is a part of the European Union, the region is the most prosperous territory in South America with the highest GDP per capita. A large part of Guianas economy derives from the presence of the Guiana Space Centre, as elsewhere in France, the official language is French, but each ethnic community has its own language, of which Guianan Creole is the most widely spoken. Guiana is derived from an Amerindian language and means land of many waters, French Guiana and the two larger countries to the north and west, Guyana and Suriname, are still often collectively referred to as the Guianas and constitute one large shield landmass. French Guiana was originally inhabited by people, Kalina, Arawak, Emerillon, Galibi, Palikur, Wayampi. The French attempted to create a colony there in the 18th century in conjunction with its settlement of some other Caribbean islands, in this penal colony, the convicts were sometimes used as butterfly catchers. During its existence, France transported approximately 56,000 prisoners to Devils Island, fewer than 10% survived their sentence. In addition, in the nineteenth century, France began requiring forced residencies by prisoners who survived their hard labor. A Portuguese-British naval squadron took French Guiana for the Portuguese Empire in 1809 and it was returned to France with the signing of the Treaty of Paris in 1814

Guadeloupe
–
Guadeloupe is an insular region of France located in the Leeward Islands, part of the Lesser Antilles in the Caribbean. Administratively, it is a region consisting of a single overseas department. With a land area of 1,628 square kilometres and a population of 400,132 as of January 2015. Guadeloupes two main islands are Basse-Terre to the west and Grande-Terre to the east, which are separated by a strait that is crossed with bridges. They are often referred to as a single island, the department also includes the Dependencies of Guadeloupe, which include the smaller islands of Marie-Galante and La Désirade, and the Îles des Saintes. Guadeloupe, like the other departments, is an integral part of France. As a constituent territory of the European Union and the Eurozone, as an overseas department, however, it is not part of the Schengen Area. The prefecture of Guadeloupe is the city of Basse-Terre, which lies on the island of the same name, the official language is French, and virtually the entire population except recent arrivals from metropolitan France also speak Antillean Creole. Christopher Columbus named the island Santa María de Guadalupe in 1493 after the Virgin Mary, venerated in the Spanish town of Guadalupe, the island was called Karukera by the Arawak people, who settled on there in 300 AD/CE. During the 8th century, the Caribs came and killed the population of Amerindians on the island. During his second trip to the Americas, in November 1493, Christopher Columbus became the first European to land on Guadeloupe, while seeking fresh water. He called it Santa María de Guadalupe de Extremadura, after the image of the Virgin Mary venerated at the Spanish monastery of Villuercas, in Guadalupe, the expedition set ashore just south of Capesterre, but left no settlers behind. Columbus is credited with discovering the pineapple on the island of Guadeloupe in 1493 and he called it piña de Indias, which can be correctly translated as pine cone of the Indies. During the 17th century, the Caribs fought against the Spanish settlers, after successful settlement on the island of St. Due to Martiniques inhospitable nature, the duo resolved to settle in Guadeloupe in 1635, took possession of the island and it was annexed to the kingdom of France in 1674. Over the next century, the British seized the island several times, the economy benefited from the lucrative sugar trade, which commenced during the closing decades of the 17th century. Guadeloupe produced more sugar than all the British islands combined, worth about £6 million a year, the British captured Guadeloupe in 1759. The British government decided that Canada was strategically important and kept Canada while returning Guadeloupe to France in the Treaty of Paris that ended the Seven Years War

Martinique
–
Like Guadeloupe, it is an overseas region of France, consisting of a single overseas department. One of the Windward Islands, it is north of Saint Lucia, southeast of Puerto Rico, northwest of Barbados. As with the overseas departments, Martinique is one of the eighteen regions of France. As part of France, Martinique is part of the European Union, the official language is French, and virtually the entire population also speak Antillean Creole. Martinique owes its name to Christopher Columbus, who sighted the island in 1493, the island was then called Jouanacaëra-Matinino, which came from a mythical island described by the Tainos of Hispaniola. According to historian Sydney Daney, the island was called Jouanacaëra by the Caribs, when Columbus returned to the island in 1502, he rechristened the island as Martinica. The name then evolved into Madinina, Madiana, and Matinite, finally, through the influence of the neighboring island of Dominica, it came to be known as Martinique. The island was occupied first by Arawaks, then by Caribs, the Carib people had migrated from the mainland to the islands about 1201 CE, according to carbon dating of artifacts. They were largely displaced, exterminated and assimilated by the Taino, Martinique was charted by Columbus in 1493, but Spain had little interest in the territory. On 15 September 1635, Pierre Belain dEsnambuc, French governor of the island of St. Kitts, dEsnambuc claimed Martinique for the French King Louis XIII and the French Compagnie des Îles de lAmérique, and established the first European settlement at Fort Saint-Pierre. DEsnambuc died in 1636, leaving the company and Martinique in the hands of his nephew, in 1637, his nephew Jacques Dyel du Parquet became governor of the island. In 1636, the indigenous Caribs rose against the settlers to drive them off the island in the first of many skirmishes. The French successfully repelled the natives and forced them to retreat to the part of the island. When the Carib revolted against French rule in 1658, the Governor Charles Houël du Petit Pré retaliated with war against them, many were killed, those who survived were taken captive and expelled from the island. Some Carib had fled to Dominica or St. Vincent, where the French agreed to them at peace. They were quite industrious and became quite prosperous, from September 1686 to early 1688, the French crown used Martinique as a threat and a dumping ground for mainland Huguenots who refused to reconvert to Catholicism. Over 1,000 Huguenots were transported to Martinique during this period, usually under miserable and those that survived the trip were distributed to the island planters as Engagés under the system of serf peonage that prevailed in the French Antilles at the time. Many of them were encouraged by their Catholic brethren who looked forward to the departure of the heretics, by 1688, nearly all of Martiniques French Protestant population had escaped to the British American colonies or Protestant countries back home

Mayotte
–
Mayotte is an insular department and region of France officially named Département de Mayotte. It consists of an island, Grande-Terre, a smaller island, Petite-Terre. The archipelago is located in the northern Mozambique Channel in the Indian Ocean off the coast of Southeast Africa, the department status of Mayotte is recent and the region remains the poorest in France. Mayotte is nevertheless much more prosperous than the countries of the Mozambique Channel. Mayottes area is 374 square kilometres and, with its 212,645 people, is densely populated at 569 per km². The biggest city and prefecture is Mamoudzou on Grande-Terre, however, the Dzaoudzi–Pamandzi International Airport is located on the neighbouring island of Petite-Terre. The territory is part of the Comoro Islands. The territory is known as Maore, the native name of its main island. The language of the majority is Shimaore, a Bantu language variety closely related to the varieties in the neighbouring Comoros islands, the second most widely spoken native language is Kibushi, a Malagasy language variety most closely related to the Sakalava dialect of Malagasy with influences from Shimaore. The vast majority of the population is Muslim, the island was populated from neighbouring East Africa with later arrival of Arabs, who brought the Islamic religion. A sultanate was established in 1500, the people of Mayotte voted to remain politically a part of France in the 1974 referendum. The term Mayotte may refer to all of the islands, of which the largest is known as Maore and includes Maores surrounding islands, most notably Pamanzi. The main island, Grande-Terre, geologically the oldest of the Comoro Islands, is 39 kilometres long and 22 kilometres wide, because of the volcanic rock, the soil is relatively rich in some areas. A coral reef encircling much of the island ensures protection for ships, Dzaoudzi was the capital of Mayotte until 1977. It is situated on Petite-Terre, which at 10 square kilometres is the largest of several islets adjacent to Maore, in 1500, the Maore or Mawuti sultanate was established on the island. In 1503, Mayotte was observed by Portuguese explorers, but not colonized, in 1832, Mayotte was conquered by Andriantsoly, former king of Iboina on Madagascar, in 1833, it was conquered by the neighbouring sultanate of Mwali. On 19 November 1835, Mayotte was again conquered by the Ndzuwani Sultanate, however, in 1836 it regained its independence under a last local Sultan. Mayotte was purchased by France in 1841 and it was the only island in the archipelago that voted in referendums in 1974 and 1976 to retain its link with France and forgo independence

Exclusive economic zone
–
It stretches from the baseline out to 200 nautical miles from its coast. In colloquial usage, the term may include the continental shelf, the term does not include either the territorial sea or the continental shelf beyond the 200 nmi limit. The surface waters, as can be seen in the map, are international waters, generally, a states exclusive economic zone is an area beyond and adjacent to the territorial sea, extending seaward to a distance of no more than 200 nautical miles out from its coastal baseline. The exception to this occurs when exclusive economic zones would overlap. When an overlap occurs, it is up to the states to delineate the actual maritime boundary, generally, any point within an overlapping area defaults to the nearest state. A states exclusive economic zone starts at the edge of its territorial sea. The exclusive economic zone stretches much further into sea than the territorial waters, thus, the exclusive economic zones includes the contiguous zone. The idea of allotting nations EEZs to give more control of maritime affairs outside territorial limits gained acceptance in the late 20th century. Initially, a countrys sovereign territorial waters extended 3 nautical miles or 6 km beyond the shore, in modern times, a countrys sovereign territorial waters extend to 12 nautical miles beyond the shore. One of the first assertions of exclusive jurisdiction beyond the territorial seas was made by the United States in the Truman Proclamation of September 28,1945. The exact extent of economic zones is a common source of conflicts between states over marine waters. One well-known example of such dispute was the Cod Wars between the United Kingdom and Iceland, Norway and Russia dispute both territorial sea and EEZ with regard to the Svalbard archipelago as it affects Russias EEZ due to its unique treaty status. A treaty was agreed in principle in April 2010 between the two states and subsequently ratified, resolving this demarcation dispute, the agreement was signed in Murmansk on September 15,2010. The South China Sea is the site of a dispute between several neighboring nations. Croatias ZERP in the Adriatic Sea caused friction with Italy and Slovenia, a wedge-shaped section of the Beaufort Sea is disputed between Canada and the United States, as the area reportedly contains substantial oil reserves. France claims a portion of Canadas EEZ for Saint-Pierre-et-Miquelon based on a new definition of the continental shelf, Saint-Pierre-et-Miquelon is entirely surrounded by Canadas EEZ. Mauritius claims EEZ for Tromelin from France and EEZ for British Indian Ocean Territory from the UK, Northern Cyprus claims a portion of Cyprus EEZ overlaps with that of Northern Cyprus in the south/southeastern part of the Cyprus island. Turkey claims a portion of Cypruss EEZ overlaps with its own EEZ, Lebanon claims that the agreement between Cyprus and Israel overlapped its own EEZ

Saint-Pierre and Miquelon
–
It is the only remnant of the former colonial empire of New France that still remains under French control, with an area of 242 km2 and a population of 6,080 at the January 2011 census. The islands are situated at the entrance of Fortune Bay, which extends into the southwestern coast of Newfoundland and they are 3,819 kilometres from Brest, the nearest point in Metropolitan France, but only 25 kilometres from the Burin Peninsula of Newfoundland. Saint-Pierre is French for Saint Peter, the saint of fishermen. The present name of Miquelon was first noted in the form of Micquelle in the Basque sailor Martin de Hoyarçabals navigational pilot for Newfoundland and it has been claimed that the name Miquelon is a Basque form of Michael, Mikel and Mikels are usually named Mikelon in the Basque Country. Therefore, from Mikelon it may have written in the French way with a q instead of a k. It appears that this is a common form in that language. The adjoined islands name of Langlade is said to be an adaptation of lîle à lAnglais, the first European encounter with Saint-Pierre and Miquelon was in 1520, by the Portuguese João Álvares Fagundes. They were made a French possession in 1536 by Jacques Cartier on behalf of the King of France, in 1670, during Jean Talons tenure as Intendant of New France, a French officer annexed the islands when he found a dozen French fishermen camped there. The British Royal Navy soon began to harass the French, pillaging their camps and ships, by the early 1700s, the islands were again uninhabited, and were ceded to the British by the Treaty of Utrecht which ended the War of the Spanish Succession in 1713. Under the terms of the Treaty of Paris, which put an end to the Seven Years War, France ceded all its North American possessions, France also maintained fishing rights on the coasts of Newfoundland. With France being allied with the Americans during the American Revolutionary War, Britain invaded and razed the colony in 1778, in 1793, the British landed in Saint-Pierre and, the following year, expelled the French population, and tried to install British settlers. The British colony was in turn sacked by French troops in 1796, the Treaty of Amiens of 1802 returned the islands to France, but Britain reoccupied them when hostilities recommenced the next year. The Treaty of Paris gave them back to France, though Britain occupied them yet again during the Hundred Days War, France then reclaimed the then uninhabited islands in which all structures and buildings had been destroyed or fallen into disrepair. The islands were resettled in 1816, the settlers were mostly Basques, Bretons and Normans, who were joined by various other elements, particularly from the nearby island of Newfoundland. Only around the middle of the century did increased fishing bring a certain prosperity to the little colony, during the early 1910s, the colony suffered severely as a result of unprofitable fisheries, and large numbers of its people emigrated to Nova Scotia and Quebec. The draft imposed on all inhabitants of conscript age after the beginning of World War I crippled the fisheries, which could not be processed by the older people. About 400 men from the served in the French military during World War I. The increase in the adoption of steam trawlers in the fisheries also contributed to the reduction in employment opportunities, smuggling had always been an important economic activity in the islands, but it became especially prominent in the 1920s with the institution of prohibition in the United States

Pays d'outre-mer
–
Overseas country is the designation for the overseas collectivity of French Polynesia. French Polynesia was formerly a territory until the constitutional reform on 28 March 2003 created the overseas collectivities. Then, on 27 February 2004 a law was passed giving French Polynesia the particular designation of overseas country while recalling that it belongs to the category of overseas collectivities. However, the Constitutional Council of France ruled that this description was merely a designation and not a legal status, the territorys new status meant a certain autonomy for French Polynesia in the Pacific region. This translated into the transfer of new areas of responsibility while protecting existing autonomy in the fields of health, development and town planning. In addition, French Polynesia gained the power to oppose the application of laws voted by the French Parliament which do not respect these areas of responsibility, furthermore, it established French Polynesian citizenship based on permanent residency - a requirement for the right to vote in regional elections. However, France maintains control over justice, security and public order, currency, defence, New Caledonia, which has the unique status of a sui generis collectivity, is also sometimes incorrectly referred to as an overseas country.

French Polynesia
–
It is composed of 118 geographically dispersed islands and atolls stretching over an expanse of more than 2,000 kilometres in the South Pacific Ocean. Its total land area is 4,167 square kilometres, among its 118 islands and atolls,67 are inhabited. Tahiti, which is located within the Society Islands, is the most populous island and it has more than 68% of the population of the islands in 2012. Although not a part of its territory, Clipperton Island was administered from French Polynesia until 2007. Following the Great Polynesian Migration, European explorers visited the islands of French Polynesia on several occasions, traders and whaling ships also visited. In 1842, the French took over the islands and established a French protectorate they called Etablissements des français en Océanie, in 1946, the EFOs became an overseas territory under the constitution of the French Fourth Republic, and Polynesians were granted the right to vote through citizenship. In 1957, the EFOs were renamed French Polynesia, French Polynesia as we know it today was one of the last places on Earth to be settled by humans. Scientists believe the Great Polynesian Migration happened around 1500 BC as Austronesian people went on a journey using celestial navigation to find islands in the South Pacific Ocean, the first islands of French Polynesia to be settled were the Marquesas Islands in about 200 BC. The Polynesians later ventured southwest and discovered the Society Islands around AD300, European encounters began in 1521 when Portuguese explorer Ferdinand Magellan, sailing at the service of the Spanish Crown, sighted Puka-Puka in the Tuāmotu-Gambier Archipelago. Over a century later, British explorer Samuel Wallis visited Tahiti in 1767, French explorer Louis Antoine de Bougainville also visited Tahiti in 1768, while British explorer James Cook arrived in 1769. A short-lived Spanish settlement was created in 1774, and for a time some maps bore the name Isla de Amat after Viceroy Amat, in 1772, Dutchman Jakob Roggeveen came across Bora Bora in the Society Islands. Christian missions began with Spanish priests who stayed in Tahiti for a year, protestants from the London Missionary Society settled permanently in Polynesia in 1797. King Pōmare II of Tahiti was forced to flee to Moorea in 1803, he, French Catholic missionaries arrived on Tahiti in 1834, their expulsion in 1836 caused France to send a gunboat in 1838. In 1842, Tahiti and Tahuata were declared a French protectorate, the capital of Papeetē was founded in 1843. In 1880, France annexed Tahiti, changing the status from that of a protectorate to that of a colony, the island groups were not officially united until the establishment of the French protectorate in 1889. In the 1880s, France claimed the Tuamotu Archipelago, which belonged to the Pōmare Dynasty. Having declared a protectorate over Tahuata in 1842, the French regarded the entire Marquesas Islands as French, in 1885, France appointed a governor and established a general council, thus giving it the proper administration for a colony.

New Caledonia
–
New Caledonia is a special collectivity of France located in the southwest Pacific Ocean,1,210 km east of Australia and 16,136 km east of Metropolitan France. The Chesterfield Islands are in the Coral Sea, locals refer to Grande Terre as Le Caillou. New Caledonia has an area of 18,576 km2. Its population of 268,767 consists of a mix of Kanak people, people of European descent, Polynesian people, the capital of the territory is Nouméa. The earliest traces of human presence in New Caledonia date back to the Lapita period, the Lapita were highly skilled navigators and agriculturists with influence over a large area of the Pacific. British explorer Captain James Cook was the first European to sight New Caledonia, on 4 September 1774 and he named it New Caledonia, as the northeast of the island reminded him of Scotland. The west coast of Grande Terre was approached by Jean-François de Galaup, comte de Lapérouse in 1788, shortly before his disappearance, from then until 1840, only a few sporadic contacts with the archipelago were recorded. Contacts became more frequent after 1840, because of the interest in sandalwood from New Caledonia, the trade ceased at the start of the 20th century. The victims of this trade were called Kanakas, like all the Oceanian people, the first missionaries from the London Missionary Society and the Marist Brothers arrived in the 1840s. In 1849, the crew of the American ship Cutter was killed, cannibalism was widespread throughout New Caledonia. On 24 September 1853, under orders from Napoleon III, Admiral Febvrier Despointes took formal possession of New Caledonia, a few dozen free settlers settled on the west coast in the following years. New Caledonia became a colony, and from the 1860s until the end of the transportations in 1897, about 22,000 criminals. Among the convicts were many Communards arrested after the failed Paris Commune, including Henri de Rochefort, between 1873 and 1876,4,200 political prisoners were relegated in New Caledonia. Only 40 of them settled in the colony, the rest returned to France after being granted amnesty in 1879 and 1880. In 1864, nickel was discovered on the banks of the Diahot River and with the establishment of the Société Le Nickel in 1876, mining began in earnest. The French imported labourers to work in the mines, first from neighbouring islands, then from Japan, the Dutch East Indies, the French government also attempted to encourage European immigration, without much success. The indigenous population was excluded from the French economy, even as workers in the mines, and they were ultimately confined to reservations. This sparked a violent reaction in 1878 as High Chief Atal of La Foa managed to unite many of the central tribes, the Europeans brought new diseases such as smallpox and measles

French Southern and Antarctic Lands
–
The French Southern and Antarctic Lands is an overseas territory of France. It consists of, Kerguelen Islands, a group of islands in the southern Indian Ocean, southeast of Africa. The territory is called the French Southern Lands or French Southern Territories. The latter excludes Adélie Land, where French sovereignty is not widely recognized, the lands are not connected to France Antarctique, a former French colony in Brazil. The territory has no permanent civilian population and those resident consist of visiting military personnel, officials, scientific researchers and support staff. The French Southern and Antarctic Lands have formed a territoire doutre-mer of France since 1955, the territory is divided into five districts, a According to new law 2007-224 of February 21,2007, the Scattered Islands constitute the TAAFs fifth district. The TAAF website does not mention their population, the data are not included in the totals. b The Îles Éparses principal station is on Tromelin. The headquarters of the district chief lies beyond the TAAF, in Saint Pierre on Réunion Island. c The Territorys principal station is Martin-de-Viviès on Île Amsterdam, the capital and headquarters of the Territorial administrator lies beyond the TAAF, in Saint Pierre on Réunion Island. Each district is headed by a chief, who has powers similar to those of a French mayor. Because there is no permanent population, there is no elected assembly, Adélie Land and the islands, totaling 7,781 km2, have no indigenous inhabitants, though in 1997 there were about 100 researchers whose numbers varied from winter to summer. Île Amsterdam and Île Saint-Paul are extinct volcanoes and have been delineated as the Amsterdam, the highest point in the territory is Mont Ross on Île Kerguelen at 1,850 m. There are very few airstrips on the islands, only existing on islands with weather stations, the islands in the Indian Ocean are supplied by the special ship Marion Dufresne sailing out of Le Port in Réunion Island. Terre Adélie is supplied by Astrolabe sailing out of Hobart in Tasmania and this register, however, is to vanish, replaced by the International French Register. The territory contains the land mass that is antipodal to the Contiguous United States. Île Amsterdam and Île Saint-Paul lie antipodal to two areas in south-eastern Colorado, near the cities of Lamar and Cheyenne Wells, respectively. The territorys natural resources are limited to fish and crustaceans, economic activity is limited to servicing meteorological and geophysical research stations and French and other fishing fleets. The main fish resources are Patagonian toothfish and spiny lobster, both are poached by foreign fleets, because of this, the French Navy and occasionally other services patrol the zone and arrest poaching vessels. Such arrests can result in heavy fines and/or the seizure of the ship, France used to sell licenses to foreign fisheries to fish the Patagonian toothfish, because of overfishing, it is now restricted to a small number of fisheries from Réunion Island

Kerguelen Islands
–
The Kerguelen Islands, also known as the Desolation Islands, are a group of islands in the southern Indian Ocean constituting one of the two exposed parts of the mostly submerged Kerguelen Plateau. They are among the most isolated places on Earth, located 450 km northwest of the uninhabited Heard Island and McDonald Islands and more than 3,300 km from Madagascar, the nearest populated location. The main island, Grande Terre, is 6,675 km2 in area and is surrounded by a further 300 smaller islands and islets, the climate is raw and chilly with frequent high winds throughout the year. The surrounding seas are generally rough and they remain ice-free year-round, there are no indigenous inhabitants, but France maintains a permanent presence of 45 to 100 scientists, engineers and researchers. There are no airports on the islands, so all travel, Kerguelen Islands appear as the Ile de Nachtegal on Philippe Buaches map from 1754 before the island was officially discovered in 1772. It is possible this early name was after Tasmans ship De Zeeuwsche Nachtegaal, on the Buache map, Ile de Nachtegal is located at 43°S, 72°E, about 6 degrees north and 2 degrees east of the accepted location of Grande Terre. The islands were discovered by the French navigator Yves-Joseph de Kerguelen-Trémarec on 12 February 1772. The next day Charles de Boisguehenneuc landed and claimed the island for the French crown, yves de Kerguelen organised a second expedition in 1773 and arrived at the baie de lOiseau by December of the same year. On 6 January 1774 he commanded his lieutenant, Henri Pascal de Rochegude, since the end of the whaling and sealing era, most of the islands species have been able to increase their population again. In 1800, Hillsborough spent eight months sealing and whaling around the islands, during this time Captain Robert Rhodes, her master, prepared a chart of the islands. In 1825, the British sealer John Nunn and three members from Favourite, were shipwrecked on Kerguelen until they were rescued in 1827 by Captain Alexander Distant during his hunting campaign. The islands were not completely surveyed until the Ross expedition of 1840, for the 1874 transit of Venus, George Biddell Airy at the Royal Observatory of the UK organised and equipped five expeditions to different parts of the world. Three of these were sent to the Kerguelen Islands, the Reverend Stephen Joseph Perry led the British expeditions to the Kerguelen Islands. He set up his main station at Observatory Bay and two auxiliary stations, one at Thumb Peak led by Sommerville Goodridge, and the second at Supply Bay led by Cyril Corbet. Observatory Bay was also used by the German Antarctic Expedition led by Erich Dagobert von Drygalski in 1902–03, in January 2007, an archaeological excavation of this site was carried out. In 1874–1875, British, German and U. S. expeditions visited Kerguelen to observe the transit of Venus, in 1877 the French started a coal mining operation, however, this was abandoned soon after. The German auxiliary cruiser Atlantis called at Kerguelen during December 1940, during their stay the crew performed maintenance and replenished their water supplies. This ships first fatality of the war occurred when a sailor, Bernhard Herrmann and he is buried in what is sometimes referred to as the most southerly German war grave of World War II
