Erosion is the process by which soil and rock are removed from the Earth's surface and transported to another location by natural forces such as wind, water, or ice. The main agents of erosion include water (rivers, waves, and glaciers), wind, and ice. These agents can wear away the land by picking up and carrying sediment from one place to another. Over time, erosion can create various landforms such as valleys, canyons, and deltas.
