Communes Of France
The () is a level of administrative division in the French Republic. French are analogous to civil townships and incorporated municipalities in the United States and Canada, ' in Germany, ' in Italy, or ' in Spain. The United Kingdom's equivalent are civil parishes, although some areas, particularly urban areas, are unparished. are based on historical geographic communities or villages and are vested with significant powers to manage the populations and land of the geographic area covered. The are the fourth-level administrative divisions of France. vary widely in size and area, from large sprawling cities with millions of inhabitants like Paris, to small hamlets with only a handful of inhabitants. typically are based on pre-existing villages and facilitate local governance. All have names, but not all named geographic areas or groups of people residing together are ( or ), the difference residing in the lack of administrative powers. Except for the municipal arrondi ...

Charente (river)
The Charente (; oc, Charanta ) is a long river in southwestern France. Its source is in the Haute-Vienne ''département'' at Chéronnac, a small village near Rochechouart. It flows through the departments of Haute-Vienne, Charente, Vienne and Charente-Maritime. The river flows into the Atlantic Ocean near Rochefort. Navigation The Charente was described by the French king François I as 'the most beautiful river in the kingdom', and was navigable in its natural state until mills were erected at many locations in the 14th century. Some locks were built but through navigation remained impossible for centuries. Improvements to the navigation were projected under Louis XVI in 1772, but work was interrupted by the Revolution. The project was revived under the Restoration and canalisation completed in 1835. The waterway was abandoned in 1957. The ''départements'' took over operation in 1963, and recreational vessels have now taken possession of the waterway throughout the 164 ...

Dry Valley
A dry valley may develop on many kinds of permeable rock, such as limestone and chalk, or sandy terrains that do not regularly sustain surface water flow. Such valleys do not hold surface water because it sinks into the permeable bedrock. There are many examples of chalk dry valleys along the North and South Downs in Southern England. Notably the National Trust-owned Devil's Dyke near Brighton covers some of downland scarp, and includes the deepest dry valley in the world – created when melting water eroded the chalk downland to the permafrost layer after the last ice age. The three-quarter mile long curved dry valley is around in height and attracts tourists with its views of Sussex, Hampshire and Kent. Other examples include the Alkham Valley near Dover, and the Hartley Bottom and Fawkham valleys near Dartford in north Kent. There are many examples of limestone dry valleys in the Peak District and the Yorkshire Wolds. A notable example is the valley of the River Manifold ...

Géoportail
Géoportail is a comprehensive web mapping service of the French government that publishes maps and geophysical aerial photographs from more than 90 sources for French territory, France and its territories. The service, first developed by two public agencies (the Institut Géographique National, IGN and the Bureau de Recherches Géologiques et Minières, BRGM), was officially inaugurated on 23 June 2006 by president Jacques Chirac. Though the French service has sometimes been described as a competitor or rival to Google Maps, it is different from Google's mapping service (launched one year before in February 2005), since they have different objectives. Geoportail makes some unusual cartographic sources available, such as the renowned 18th-century French cartography#Cassini maps, Cassini maps and the Napoléonic-period Minutes État-Major, in addition to IGN road maps, administrative maps, topographic maps, cadastral and building surveys, public service utility maps, transportation ...

Peat
Peat (), also known as turf (), is an accumulation of partially decayed vegetation or organic matter. It is unique to natural areas called peatlands, bogs, mires, moors, or muskegs. The peatland ecosystem covers and is the most efficient carbon sink on the planet, because peatland plants capture carbon dioxide (CO2) naturally released from the peat, maintaining an equilibrium. In natural peatlands, the "annual rate of biomass production is greater than the rate of decomposition", but it takes "thousands of years for peatlands to develop the deposits of , which is the average depth of the boreal orthernpeatlands", which store around 415 gigatonnes (Gt) of carbon (about 46 times 2019 global CO2 emissions). Globally, peat stores up to 550 Gt of carbon, 42% of all soil carbon, which exceeds the carbon stored in all other vegetation types, including the world's forests, although it covers just 3% of the land's surface. ''Sphagnum'' moss, also called peat moss, is one of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clay
Clay is a type of fine-grained natural soil material containing clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4). Clays develop plasticity when wet, due to a molecular film of water surrounding the clay particles, but become hard, brittle and non–plastic upon drying or firing. Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour from small amounts of iron oxide. Clay is the oldest known ceramic material. Prehistoric humans discovered the useful properties of clay and used it for making pottery. Some of the earliest pottery shards have been dated to around 14,000 BC, and clay tablets were the first known writing medium. Clay is used in many modern industrial processes, such as paper making, cement production, and chemical filtering. Between one-half and two-thirds of the world's population live or work in buildings made with clay, often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quaternary
The Quaternary ( ) is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy (ICS). It follows the Neogene Period and spans from 2.58 million years ago to the present. The Quaternary Period is divided into two epochs: the Pleistocene (2.58 million years ago to 11.7 thousand years ago) and the Holocene (11.7 thousand years ago to today, although a third epoch, the Anthropocene, has been proposed but is not yet officially recognised by the ICS). The Quaternary Period is typically defined by the cyclic growth and decay of continental ice sheets related to the Milankovitch cycles and the associated climate and environmental changes that they caused. Research history In 1759 Giovanni Arduino proposed that the geological strata of northern Italy could be divided into four successive formations or "orders" ( it, quattro ordini). The term "quaternary" was introduced by Jules Desnoye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kimmeridgian
In the geologic timescale, the Kimmeridgian is an age in the Late Jurassic Epoch and a stage in the Upper Jurassic Series. It spans the time between 157.3 ± 1.0 Ma and 152.1 ± 0.9 Ma (million years ago). The Kimmeridgian follows the Oxfordian and precedes the Tithonian. Stratigraphic definition The Kimmeridgian Stage takes its name from the village of Kimmeridge on the Dorset coast, England. The name was introduced into the literature by French geologist Alcide d'Orbigny in 1842. The Kimmeridge Clay Formation takes its name from the same type location (although this formation extends from the Kimmeridgian stage of the Upper Jurassic into the Lower Cretaceous). It is the source for about 95% of the petroleum in the North Sea. Historically, the term Kimmeridgian has been used in two different ways. The base of the interval is the same but the top was defined by British stratigraphers as the base of the Portlandian (''sensu anglico'') whereas in France the top was defined as t ...

Late Jurassic
The Late Jurassic is the third epoch of the Jurassic Period, and it spans the geologic time from 163.5 ± 1.0 to 145.0 ± 0.8 million years ago (Ma), which is preserved in Upper Jurassic strata.Owen 1987. In European lithostratigraphy, the name "Malm" indicates rocks of Late Jurassic age. In the past, ''Malm'' was also used to indicate the unit of geological time, but this usage is now discouraged to make a clear distinction between lithostratigraphic and geochronologic/chronostratigraphic units. Subdivisions The Late Jurassic is divided into three ages, which correspond with the three (faunal) stages of Upper Jurassic rock: Paleogeography During the Late Jurassic Epoch, Pangaea broke up into two supercontinents, Laurasia to the north, and Gondwana to the south. The result of this break-up was the spawning of the Atlantic Ocean. However, at this time, the Atlantic Ocean was relatively narrow. Life forms of the epoch This epoch is well known for many famous types of dinosau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
