Blurring with the formation of valleys

But the same is repeated in significant amounts. For example, in the Alps in Shluderbaha, in the Tyrol, the so-called three teeth present in their three fantastic high pyramids balance of the whole system that once occupied the whole area. If the principal features of the earth's surface topography is determined by orogenic processes, in any case the details of it are the result of razmyvayuschey of water: in a few million years, she razed to all continents with the surface of the sea, if, on the other hand, was not restored and destroyed continuously. Not only flowing water, but ice is one of the leaders of destruction. Glaciers descending from the mountain heights into the valleys, as well as continental ice polar countries are destroying the rocks on which they lie, in the depths of his ice masses are fragments of rocks and repent of them in the so-called moraines. However, with respect to the role played in the history of the land of ice activities, opinions diverge. Anyway, he is one of the most interesting figures of geological changes. Layered rocks were deposited under water and buried in the mass remains of animals and plants that lived there or were there recorded. If these organisms are capable to preserve, but now we find their remains are called fossils to study the past is the subject of paleontology. Study them in many ways is difficult due to the fact that all the soft parts of them have disappeared, however failed to show that in the past era of land inhabited the huge number of extinct forms. Some of them are in close kinship with modern, others had a kind of organization. By comparing them with close to them types of our fauna and flora was made possible with sufficient accuracy to recover the structure of most of them. The sequence of precipitation, as well as fossils found in them, and comparing members of different places together, we conclude that in this respect there is a strict pattern. In this way, and managed to break the story of the land into large and smaller periods and establish a perfect chronology, the elucidation of which is the subject of historical geology.
