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
Imagine that you are swimming in a deep lake and can’t see the bottom. You only feel samarajiva cold water under a water and deep, stretching into infinity. Many people are afraid of depth, and even the best swimmer in the world may experience fear after the stories about the legends and mysteries Shrouding the bottomless water of the deepest lakes in the world. The depth of any lake change with the climate and seasons of rains, but overall, there are certain constants. Today we explore the top ten deepest lakes in the world, learn about their history and secrets.
10. Lake Matano
9. Crater Lake
With striking volcanic past, crater lake National Park is located in crater lake in Oregon. It is a place of immeasurable beauty, surrounded by cliffs 600 meters high, with two small Islands. Crater is a breathtaking open sea, a real laboratory for photographers. It is the deepest lake in the United States, with a maximum depth of 594 meters and with the purest water in North America (from the point of view of the absence of pollutants). The lake is fed by melting winter snow. The crater was formed 7,700 years ago after a violent eruption, but the legend can tell a lot more about it. Indian Continue reading
