Most landscapes show obvious evidence of erosion.
Erosion is responsible for the creation of hills and valleys.
It removes sediments from that were once glaciated, shapes the shorelines of lakes and coastlines, and transports material downslope from elevated sites. Erosion also requires a medium to move material. Wind, water, and ice are the mediums primarily responsible for erosion. Finally, the process of erosion stops when the transported particles fall out of the transporting medium and settle on a surface. This process is called deposition .
