Concept in Definition ABC

Erosion is called the wear process suffered by the bedrock that forms the I usually as a consequence of exogenous geological processes such as the currents of Water or glacial ice, strong winds, changes in temperature and the action that living beings carry out on it.

Among the material that is most easily eroded is: the fragments of rocks created by mechanical abrasion as a result of the action of the wind, the surface waters, glaciers and soil, created by the chemical breakdown of rocks by combining weak acids dissolved in water superficial, bacteria, organic acids, plants, among others.

Water is considered the most important factor in erosion, meanwhile, the vegetation on the ground is usually one of the main allies and protective layers against it itself, however, the absence of this, either for reasons of natural disaster or because the action of man plan the building of some structures or the substitution of natural vegetation by crops that will obviously contribute to the infertility of the soil will, of course, increase the chances of erosion, that is, a road without drainage will make the roads begin to observe their asphalt gotten up. Also, although to a lesser extent than water, plate tectonics and volcanism do their thing to do their bit in favor of erosion.

On the one hand, erosion can be natural and progressive, that is, it will develop around something natural and will take several years to be produced and on the other, the most harmful, called accelerated because it will develop very quickly and its effects will be felt in a very short period of time. weather. Among these is in the first place the unscrupulous action of the human being that we mentioned above.

The most common types of erosions are: by water or river, that which occurs as a consequence of displacement of water that will make the earth wet first and then wash out; marine, by the constant action of waves, tides and currents; the glacier is very common in the mountains, but of course it will depend on where it is located. If it is a valley, when the glaciation passes, it leaves the ground very smooth and with a perfect U shape; wind power is produced thanks to the wind that carries small particles that will later hit the rocks, multiplying into more particles; biotic, caused by chemical processes that support the rocks in which issues such as heat, cold and water intervene.
It occurs a lot in polar regions or in which there are sudden changes in the weather and karst, occurs when a significant amount of water enters the earth producing deep holes or gaps. This situation occurs a lot in underground rivers.

Among the main and best solutions that experts give to reduce the effects and prevent erosion are. do not burn the stubble, do not till and keep the rest of the crop on the surface of the soil.
