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.
Lesson Summary. 1  Water flowing over Earthâs surface or underground causes erosion and deposition. 2  Water flowing over a steeper slope moves faster and causes more erosion. 3  How water transports particles depends on their size. 4  Runoff erodes the land after a heavy rain.
