The lake basin can be both endogenous and exogenous origin that have the most significant impact on their size, shape, water regime.
The largest lake basins of tectonic origin. They are located either in a simple tectonic structures in the basin in the plains (Ilmen, Chad) or in foothill and intermountain depressions (Balkhash), or in the grabens of the rift (Baikal, Nyasa, Tanganyika). But most of the major lake basin has a complex tectonic origin, in their education are involved as concave folds and breaks of the earth’s crust (Issyk-Kul lake. Victoria, etc.). All tectonic lakes are large in size and significant depth, and rift – an elongated and narrow shape in plan, very large depth, steep slopes. The bottoms of many deep lakes lie below the sea level, having a mirror above the water level, is cryptodepression (Baikal, Ladoga, etc.). In the location of tectonic lakes are observed certain regularities: they are concentrated along faults of the earth’s crust (the Syrian-African and Baikal rift zone), or framed panels: along the Canadian shield is a Large bear, Great Slave, Winnipeg, Athabasca, Great North American lakes; the Baltic shield along the Vyg, Segozero, Onega, Ladoga, etc.
The lakes occupy volcanic craters and calderas of extinct volcanoes or depressions in the surface of solidified lava flows (Kronotsky lake on the Kamchatka Peninsula, lake Java, Continue reading

Tops the list the largest lakes Caspian sea. It is located at the junction of Asia and Europe. The sea is called because of the huge size. Is a salty lake. The area of the sea is 371000 square kilometers Stretching from West to East — 315 km, from North to South and 1,200 km. On the lake are about 50 Islands, a dozen of peninsulas and bays. In the Caspian sea flow into rivers such as the Terek, Volga, Urals. The pond washes the shores of Iran, Kazakhstan, Turkmenistan, Russia and Azerbaijan. On the shores are the cities of Baku, Turkmenbashi and Makhachkala, Kaspiysk. In the Caspian sea is home to 101 fish species, as well as possible to meet seals. On the shelf of the pond works on oil, limestone, salt, sand and clay.
Second place in the rating occupies the Upper lake located on the border of USA and Canada. Equal has an area of 82700 square km lake superior is the largest freshwater body in the world. Located at an altitude of 183 m above sea level and formed due to melting of glaciers. The coastline is rugged, steep and rocky. The lake is rich with trout, sturgeon, whitefish and other species of fish. Navigation is well developed. The chief ports are thunder Bay, Ashland, and Duluth Superior.
Closes the three large lakes of the world — Victoria. It is located in East Africa, on the border Continue reading
