Erosion

Erosion refers to the process of weathering and transporting the materials around the earth like soil and rock. The erosion force usually occurs by the wind, water and natural slopes or some chemicals like acid rain


Although the erosion process is from the nature but lately it has been increased because the wrong behaving of human in dealing with nature resources, these like deforestation and the huge industrial revolution



One of the main causes of erosion is the gravity effect, on edged or creep sloped areas, the particles leave its places from higher levels to lower land due to gravity. The obvious example for erosion caused by the force of water is the shores erosion, it happens because of the tides effect. On very huge scale, erosion can happen by the movement of crust (the outer layer of the earth), in this case, erosion is caused by Tectonic effects
