Erosion. 1  Rainfall-Rainfall can cause erosion both when the rain hits the surface of the Earth, called splash erosion, and when raindrops accumulate and flow like small streams. 2  Rivers-Rivers can create a significant amount of erosion over time. 3  They break up particles along the river bottom and carry them downstream.
Flowing water plays a major role in erosion by carrying away soils and other materials on the land surface. In general, there is a potential for water erosion where the land slope is at least 2 percent. The four types of water erosion of soil are sheet, rill, gully, and tunnel. Sheet erosion is the uniform removal of soil without the development of visible water channels. It is the least apparent of the four erosion types.
