Difference Between Erosion and Corrosion. Both corrosion and erosion happen due to certain external actions on a surface. Corrosion means the destruction of materials through chemical reactions whereas erosion means the carrying away of the topsoil from the surface of the earth. Corrosion normally happens because of chemical reactions.
These agents can be mechanical, chemical or biological. Erosion is a form of mechanical weathering, and occurs when the movement of a force like rain water or moving water sources like a river wear down the surface of rocks and carry the worn away parts with the flow of the water to other areas. Erosion can also occur with forces like wind, glacier movement, tides or waves.
