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
Killarney (which means “Church thorn branch”) is located on the coast in the South-Western corner of Ireland. There are well-known lakes of Killarney.
The beauty of the surroundings and a large selection of activities and occupations make Killarney one of the most popular tourist destinations of Ireland. Once a small town, Killarney is alive today due to the developed tourism infrastructure.
The charming Irish town of Killarney is located on the border of the national Park, the heart of which are 3 lakes – Upper, middle and Lower. Exploring the local sights, walking through the Park on foot, by Bicycle, in a carriage pulled by a pretty heavy, or. top. One-, two – and three-hour walks through the Park can be enjoyed at the stables, located on the outskirts of Killarney town (about 3 km from the centre of the city).
In this town specialize in servicing the tourist horse trails, so horses are cool and calm Irish draught. All well run under the saddle, however, the speed that they develop. It’s best to stop by or call and sign up for the next day to the owners of the stables had the opportunity to prepare the horse and alert the instructor. Continue reading
