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.

According to a Virginia Tech environmental professor, most of the soil particles end up flowing with the water sources, such as lakes, rivers or the ocean.
