Most people have a vague understanding of the difference between the lake and the sea due to the historically-established names of the Caspian, Aral and Dead sea, actually being lakes, and lake Baikal, which the locals proudly call the sea, shocked by his size and magnificence.
The lake is a closed depression in the earth’s continental crust, which is filled with water. Lake waters belong to the land, along with rivers, swamps, glaciers and groundwater. A leader in the parameter area in the world is the Caspian sea, there is no depth of the reservoir equal to the Baikal. He is a key reservoir of fresh water for humans.
Lake classification is a consequence of how the lake deepening. Highlights – this is a tectonic lake that was the result of discontinuous horizontal or vertical movements of the earth’s crust. Over time, the fracture gap is filled with water. Thus was formed the lake Baikal, African lakes Nyasa and Tanganyika. With the lowering part of the continental plate due to the emergence of the Caspian and Aral seas.
Lakes are formed when the rock-fall. Thus perevarivaetsya the river bed, necessarily flowing in a mountain valley. A huge number of such lakes in the Pamir and in mountains of Asia Minor. Continue reading
We know that on Earth there are many places with extreme habitat, which sometimes look quite harmless and friendly, but it is hardly possible to say something similar about lake Natron. Should try to describe it in colors, like immediately come to mind only such epithets as alien, bloody and lifeless, that is partly true.
The lake appeared in the midst of the mountain massif of the East African rift, near the border with Kenya and in close proximity to the volcano Ol Doinyo of Lengai. Seismic activity began in this region over 2 million years ago and becoming commonplace for many years, gradually changed the landscape and has refined the earth’s crust, preparing the space for lakes such as Natron, Manyara and Eyasi. Mountain river has eroded the volcanic rocks and formed in the lowlands reservoirs, each of which acquired certain characteristics and, perhaps, the most bizarre brainchild turned out it was the Natron.
With special bacteria which gives the lake a red tint, the pond becomes like a creation of science fiction writers, just like the ocean is sentient protoplasm from the book “Solaris”. Moreover, the lake temperature reaches 50-60 degrees Celsius and the alkaline level is off the charts – it makes the pond is totally unsuitable for most Continue reading
Lakes are sources of the largest rivers in Africa that provide water and lots of fresh fish inhabitants of the “dark continent”. They are home to unique aquatic and terrestrial species. Africa has some of the biggest lakes in the world – Victoria, Chad, in the centre of the continent, and Tanganyika, lying between the Democratic Republic of the Congo, Burundi, Tanzania and Zambia. Most large lakes in Africa are located along the continental fault known as the East African rift valley. Let us consider seven of the biggest lakes in Africa.
Lake Victoria (pictured) in East Africa located on the lands of Kenya, Tanzania and Uganda. 69484 with an area of square kilometers, the lake size can be compared with Ireland. Victoria gets its water from many rivers, the largest is the Kagera. Water from the lake then drains into the river via the Owen falls, where hydroelectric power plants are artificial. It is the second largest freshwater lake in the world, where there are major ports, countless small fishing villages. Green grassy shore of Homa Bay, Kenya are the ideal base from which to explore the wildlife of lake Victoria. Crocodiles and hippos grazing on the shores, and boat trips Continue reading
