This document discusses different types of erosion and deposition caused by various natural forces. It describes how moving water, glaciers, waves, and wind can erode and transport sediment, and where sediment is deposited. Specific erosion and deposition features are defined, such as rills, gullies, deltas, moraines, beaches, and sand dunes. The document also explains factors that influence the erosive power of moving water and glaciers, such as slope, volume of water, and shape of the landscape.
