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.
Erosion begins with a process called weathering; in this process, environmental factors break rock and soil into smaller pieces, and loosen them from the earth's surface. When the wind whips up a dust storm that stings our eyes, its ability to move sand is very clear. But the most powerful erosive force on the earth is not wind but water, which causes erosion in its solid form of ice and as a liquid. Water in its liquid form causes erosion in many ways. Streams from tiny creeks to huge rivers carry tons of eroded soil and rocks every year.
