THE EROSION Called "erosion" a series of natural processes of physical and chemical nature that deplete and destroy the soil and rocks in the crust of a planet, in this case, Earth. Land erosion is the result of the combined action of several factors such as temperature, gas, water, wind, gravity, and plant and animal life. In some regions dominated any of these factors, like wind in dry areas.
