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.
Water erosion occurs when rain, spring run-off, or floodwater carry soil particles away. This can occur through sheet erosion, where soil materials are removed relatively uniformly, or rill erosion where flowing water creates small channels in the soil, called rills, and larger channels, called gullies.heet erosion is caused by raindrops. Sheet erosion is defined as the uniform removal of soil in thin layers from sloping land. This, of course, is nearly impossible; in reality the loose soil merely runs off with the rain.
