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
Looking at a map, on all continents, you can see the lake. Some of them elongated, others rounded. Some lakes are located in mountainous areas, others on vast flat plains, some very deep and some very shallow. The shape and depth of the lake depend on the size of the basin which it occupies. Lake basins are formed by different ways.
Most of the major lakes of the globe is of tectonic origin. They are located in major deformations of the earth crust in the plains or fill the deep tectonic crack — rift (lake Baikal, Tanganyika, Nyasa, etc.).
Lake basins can become craters and calderas of extinct volcanoes, and sometimes depressions on the surface of lava flows. These lakes are called volcanic, are found, for example, on the Kuril and Japanese Islands, in Kamchatka, on the island of Java and in other volcanic regions of the Earth. It happens that the lava and fragments of igneous rocks dammed the river valley in this case also there is a volcanic lake.
The basin of the lake Kaali in Estonia is of meteoritic origin. It is located in the crater formed by the fall of a large meteorite.
Glacial lakes fill hollows formed as a result of the glacier activity. Moving, Continue reading
The Hillier lake (Lake Hillier) located on the Middle island ( Middle Island ), the biggest of the Islands and islets that make up the archipelago Recherch ( Archipelago of the Recherche ), scattered along the southern coast of Western Australia .
Small salty lake-Hillier . surrounded by a belt of white salt, more like something fabulous and Woosnam than the actual natural formation in the middle of the ocean. On all sides it is surrounded by the greenery of various species of eucalyptus and paper trees, which from the dark-blue waves of the ocean separates the narrow strip of white sand.
The peculiarity of this lake is its bright pink color . The color is permanent and does not change when water is taken into the container. The length of the lake is about six hundred meters. A narrow strip of land consisting of sand dunes and covered with vegetation separates the lake from the ocean.
Serenely and majestically stretches of the Australian coast mysterious, surrounded by many legends and fascinating beauty of the pink lake Hillier.
It is a miracle lake on middle island (eng. the “Middle Island”), which is part of the archipelago, consisting of hundreds of small Islands and stretches for many kilometres along the southern coast of Australia. The entire island Hillier Continue reading
