Endogenous processes in the Earth's mantle beneath the crust, have a much greater impact on the terrain, as their strength above, and the results appear faster.The Earth's crust - is not stable and continuous crust on the surface of the mantle, it has cracks, cracks, holes, some parts of which are superimposed on each other.Under it moves molten rock that is in some places the earthquake - the tremors, which resulted in the earth's crust cracks and upheavals.In other cases, magmatic processes lead to eruptions of volcanoes erupting from pockets of lava and rock fragments that form wide craters, high mountains and entire i
movements of lithospheric plates cause major changes in the topography of the Earth.So, the scientists suggest that the highest mountains on the planet - the Himalayas - formed from the collision of the Indian subcontinent, which was a separate island, and Eurasia.The thickness of the slab at this place was very thin, resulting in easy to start to form folds, which continue to grow until now.Endogenous processes are also volcanic hot springs and geysers, but they have less impact on the terrain.All of these external forces can pretty quickly to change certain parts of the earth's crust: there are cases when the volcano suddenly appeared, and a few hours at their place of high mountains grow.Plate movements and changes in relief that they are due to occur much more slowly, but the results are more significant.
external processes that have an impact on the relief is called exogenous.The first is the action of wind and water.It called the gradual destruction of the weathering of rocks due to the flow of air, but there is also a chemical weathering.The water may be dissolved chemicals that contribute to more rapid destruction of the rock.As a result of weathering of whole mountains disappear and in their place are flat plains.This is a very slow process that takes millions of years.Water may also seriously affect the relief penetrates deep river bed, forming wide valleys, towering cliffs and vast canyons.Shape the terrain glaciers in the Ice Age layers of ice left in many parts of the Earth its mark.
