In order to answer the question about what is the biggest lake in the world, need to be clear that this lake.This concept includes the internal waters, located on any continent lacking for and connection with the oceans.
Sea and sea basin, usually formed when the tectonic shifts taking place crust.It appears so, and the largest lake in the world - the Caspian Sea and the Caspian Sea.Why is the sea?Separated from the world's oceans during the motion of the Earth's crust, the Caspian Sea has become draining, but the water while retaining its saltiness, and the bottom is covered oceanic type crust.Incidentally, salinity reaches 13%.As for the area and depth, the largest lake in the world - the Caspian - has an open water surface (mirror), equal to three hundred and seventy-one thousand square kilometers and a maximum depth equal to twenty-five thousand meters.
is a lake on the Eurasian continent.Coastline length of six thousand seven hundred kilometers.In the eastern part there are about fifty islands.The Caspian Sea feed one hundred thirty rivers.The major waterways flowing into the largest lake in the world, are as follows: Volga, Ural and Terek.And the largest city located on the shores of the Caspian Sea, is Baku.Sturgeon, carp, pike - it is only a fraction of the species diversity, but in general more than a hundred species of fish inhabit the waters of the Caspian Sea.
However Caspian Sea - the largest salty, but the Baikal is the largest freshwater lake in Russia.In addition, it is also the deepest lake in the world.The total surface area of 31,722 square kilometers and a depth of more than fifteen hundred meters.The largest lake in Russia affects the volume of lake water, which exceeds twenty-three thousand five hundred cubic kilometers.It is the largest natural reservoir.The waters of the lake is filled with natural basin surrounded by mountains.Their distinguishing feature - is almost completely lacking organic matter and minerals, and even in winter the water is so transparent that the bottom can be seen even at a depth of thirty-forty meters.The flora and fauna of Lake Baikal is striking: two thousand seven hundred species, including nearly three dozen fish found only here and nowhere else.
actually big and have a huge lake on almost every continent.North America, for example, is famous for its lakes Michigan and Huron, the total surface area of which - almost 120 thousand square kilometers.And the area of Lake Superior, located in the same place, in North America, more than eighty-two thousand square kilometers.The origin of the reservoir due to the melting of glaciers.Is the largest, deepest and cold.In East Africa, it has its largest lake - Victoria - with an open surface area of almost 69,000 square kilometers, but its depth is small.A huge amount of rain - the main source of water replenishing Victoria.From freshwater lakes is the second largest and second only to the upper.
Returning to Russia geographically, can not remember another lake, which was once the fourth in the world, and today is on the brink of extinction - the Aral Sea.Shoaling process is very fast.The two main water arteries - the Syrdarya and Amudarya, carry their waters to the Aral Sea, but over half a century people actively collects and uses the river water for agricultural irrigation.Scientists have for many years struggling with the problem of saving the Aral Sea, but to no avail.Save Lake, located between Kazakhstan and Uzbekistan, it is unfortunately not possible.
