Weathering and erosion are both natural geological processes that act on the matter on the surface of the earth such as rocks and soil and cause them to move and reshape the surface of the earth. Weathering refers to the breaking up of the rocks into smaller fragments that ultimately change the size and structure of the rocks. Forces of nature are for the most part responsible for this process. Erosion, on the other hand, involves several processes such as wind, water flow, and movement of ice, which results in the change from one location to another.
