We call "erosion" a series of natural processes of a physical and chemical nature that wear and destroy the soils and rocks of the crust of a planet, in this case, the Earth.
Terrestrial erosion is the result of the combined action of several factors, such as temperature, gases, water, wind, gravity and plant and animal life. Some of these factors predominate in some regions, such as wind in arid areas.
Also, and much more in recent times, accelerated erosion occurs as the result of human action, whose effects are perceived in a much shorter period of time. Without human intervention, these soil losses due to erosion would be compensated by the formation of new soils in most of the Earth.
In this chapter we will see what erosion is and how it occurs.
