In the five years of the action “360 minutes for Baikal” from the shores of the lake took out 140 trucks garbage
Annual all-Russian action of En+ Group “360 minutes for Baikal” this year will be held for the fifth time. In honor of the anniversary, the organizers decided to hold it in the form of eco-marathon, which consists of five environmental activities. As noted by the Director of public relations En+ Group Elena Rollins . “all shares of marathon dedicated to educational changes on the lake Baikal. June 18, on the Small sea began to work the robotics, for ten days in it will be trained 90 trainers on robotics. They also will clean coast of Baikal”.
On the same day, 50 employees the EuroSibEnergo removed debris from another point on the coast — on the territory of Baikal biosphere reserve, near the village of Tankhoi. Thus, the ecological marathon is held simultaneously on the territory of two regions — Irkutsk region and Buryat Republic.
For several hours the volunteers collected 400 bags of trash and about a ton of scrap metal. All the garbage (aluminum cans, plastic bottles, glass and scrap iron) will be sent for recycling or disposed of in a special way.
The second stage of the marathon with the participation of young professionals from the camp of Energomera will be held in a month. Continue reading
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
