Lakes, formed from river oxbow lakes, are relatively small. Large arose in other ways. Some in valleys, blocked by avalanche or moraines, rock ridges left by retreating and now-vanished glaciers or dams erected by man. Lake Baikal in Siberia and lake in East Africa filled the huge cracks in the earth’s crust, caused by powerful shifts. American Great lakes lie in the basin, formed during the ice age when the ice wore a large part of the continent. Glaciers not only plowed a deep bowl in the valleys, along which, but this entire region sank under the weight of ice, gavluvsga a lot of the continent in plastic basalt layers under it. Then the ice melted relatively quickly, but the concavity is not yet corrected.
Around the perimeter of the great lakes in shallow bays among marsh grasses the animals and their lifestyles are not much different from what we observed in a small freshwater reservoirs. Over them worn different dragonflies, among the plants reproduce gnats and mosquitoes; hiding in the mud snails and bivalves; fish and piranhas hunt, carp and Cichlidae pluck the plants. But where the lake bottom out to a great depth, the conditions have dramatically changed.
Baikal is the deepest lake in the world. In some places the bottom is a mile from the surface. Of course, compared to the ocean it’s not much of depth, but in ocean Continue reading
How many beautiful and amazing places on planet Earth? The answer to this question is nobody knows. Impossible to count them, to study, and then describe each in detail, is unrealistic. However, experts in this field of work, exploring unique places, and find there are various findings that, first defy explanation, and secondly, self-education, amazing places, causing a lot of theories, versions, disputes and extraordinary hypotheses. Of course, all of the above relate to the American state of Texas, such as unique and interesting and amazing places located in it.
There are many interesting places if possible to visit, but the most unique is the resulting lake “Hamilton Pool”, forty kilometers from the small town of Austin. The lake was formed by itself, however, as the majority of lakes on earth. Its formation was provoked by the erosion, the result of which collapsed the dome of an underground river, and formed an unusual appearance, but at the same time a beautiful lake. The uniqueness of the lake is not in its smooth shores and clean water, unique flora or overhanging the water earthen walls and ceilings, like domes, and not even in his fifteen meter waterfall. The uniqueness Continue reading
