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
On our planet a great number of lakes, created by nature. But some of her creations are not only beautiful but also very unusual. Not coincidentally, they are among the most beautiful places of our planet and become landmarks of the countries in which they are located. Here are some of them.
Lake Morning Glory
The lake is a Morning glory in Yellowstone National Park (USA). It is a very unusual body of water: the highlight of it is that it has a non uniform bright color and shape of the bottom in the form of pipes. The lake received the poetic name in the 19th century; it then was a beautiful bright purple color. The rumor about wonder lake quickly spread through the world, and the lake became the attraction of these places. Some come to admire the beauty of the lake were throwing coins to come back again, others garbage. All this led to the fact that the heat source that feeds the lake, was clogged; the water multiplied microorganisms, which resulted in a color change. The water itself is very transparent, and the color changes depending on the weather, temperature and number of microorganisms in the water.

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
