A lakes (from Latin lacus) is a water body, usually sweet, to a considerable extent, which is separated from the sea. Water supply to lakes from rivers, groundwater and precipitation on the water surface (clear lake veterinarian). The lakes are formed in topographic depressions created by a variety of geological processes such as tectonic movements, mass movements, volcanism, formation of bars, action of glaciers and even meteorite impacts. There are also artificial lakes created by a dam.
The glaciations have caused most of lakes. In Canada, Finland, parts of Scandinavia and the Alpine lakes abound whose alignment points during the ice flow. During a glaciation occurred in areas of high latitudes, ice masses up to 5 km thick crust deepened. As glaciers advanced and retreated, ice, cutting its cargo of crystals, rubbed the bottom of valleys, opened cavities formed between peaks and rocky debris barriers (moraines).
The latter acted as a dam that trapped meltwater and formed as the Finger Lakes of New York and Lucerne, Como and Garda in Alps. The five Great Lakes (Canada-US) originated Similarly, at the end of last ice age, 15,000 years ago. The Baltic Sea also emerged at that time, as the Scandinavian ice sheet - which covered most of northern Europe - melted. Types of lakes.
As the lakes is deeper, more important is the thermal inertia and chemistry of waters. By contrast, some large bodies of surface water and shallow lakes have a sensitivity and respond immediately to environmental changes (climate, hydrology, pollution, human activities). This applies as well, but at other scales to ponds spatiotemporal and seas.
Coastal marsh or lakes, produced by filtration or flood at high tide, given its proximity to sea. They are salt, fresh or brackish water and generally contains sandy bottoms. Estero, produced by filtration or flood floods, given its proximity to rivers or lakes. (Do not confuse with estuary). A floodplain lakes is not considered because no definite basin.
Subglacial lakes, produced by the pressure under great glaciers that maintain liquid water below the ice. In Antarctica there are many subglacial lakes, Lakes Vostok is the largest. Freshwater fjord, where sea level rise becomes fjords ancient glaciers shaped channels lakes, including Lakes Como, Lakes Garda and other sudalpinos lakes in Italy. Laguna lakes formed in an island which in turn is within a lakes, for example: Manitou Lakes Manitoulin Island in Lakes Huron in Ontario, Canada. The folding of earth's crust (lithosphere) create depressions that accommodate the largest lakes. Bark undulates due to pressure, causing rises rounded called "domes".
Finally, the different layers of water moving in depth due to temperature differences, depending on the depth, the day and seasons. Lakess are more or less thermally stratified, depending on the pH, oxygen and ecologically. This stratification, which may be subject to significant seasonal variations, can be recorded in sediments, and the levels of certain contaminants.
Tectonic lakes formed in depression of a fault or rift valley that deform the crust, which are long and deep as Lakes Victoria, Lakes Titicaca or Lakes Baikal in Siberia, which has more than 1,600 m deep. Violent eruptions originate depressions containing the most beautiful lakes. At the outbreak through an opening, the melt craters pierced domed shaped vessel measuring up to 1.6 kilometers in diameter. Such lakes there are in Central America, Iceland, Italy, Germany and New Zealand. Caldera lakes are much larger and occur when the edge of a volcano collapses into magma chamber empty.
