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 Great Lakes have no outlet to sea are also called "closed seas" as the Caspian Sea, but the rule is unclear, because it speaks of Dead Sea and the Great Salt Lakes. Sometimes it is proposed to distinguish the waters of lakes by the character of salty seawater and freshwater lakes. Another example of a lakes has no outlet to sea is Lakes Valencia in Venezuela.
Natural reservoir, produced by collapse of slopes, freezing with formation of ice sheets or small dams built by beavers. Artificial lakes, also called dam, reservoir, and if lower pond. Built for various purposes such as agricultural reservoir, source of drinking water, hydroelectric dam, flood prenvention, to facilitate navigation, recreation, water sports and can usually be a multipurpose reservoir. Best known examples are the Itaipu Dam between Brazil and Paraguay, Guri Dam in Venezuela and the Three Gorges Dam in China.
Glacier Lakes, produced by the dynamics of thick ice (ice cap) in field slope during the Pleistocene, causing depressions and drumlins in field. Example: In Canada, 60% of world's lakes and the vast majority are glaciers, this is due to drainage network that characterizes this territory. In Finland there are 180,000.
Some volcanoes have crater lakes, some of which are acidic and highly mineralized lakes (Note: also known as lava lakes). The relatively closed lakes have a vulnerability to certain invasive species when they have been made tom (intentionally or not). Lakes receive water from one or more generally upstream rivers, either by springs or glacier. Water drains naturally, mainly by a river called emissary or also by evaporation. Lakes play an important reservoir of fresh water used by humans for crop irrigation, for drinking water, and in some cases to produce electricity.
The prevalence of arid climate in region reduces or eliminates the fluvial erosion allowing a basin remains closed without drainage mechanisms into oceans. The aridity determines that the water supply is less evaporation, which causes the lakes retain their salts. According salinity can be salty, brackish, hypersaline or dry.
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.
Some mollusks (snails and bivalves), depending on whether or not colonize deep lakes area may be indicators of anoxia or toxicity. It is possible to deduce the origin of a lakes if its outline is observed. A lakes is a body of water in a depression in ground. Lacustrine depressions are formed from one or more subsurface forces.
