The wearing away of rocks and soil is called erosion. Erosion is a natural process that involves the movement of soil, rock, and other materials from one place to another by the action of wind, water, or ice. Erosion can be caused by both natural processes such as weathering and human activities such as deforestation, mining, and construction. The effects of erosion can be seen in various landforms such as canyons, valleys, and river deltas, and it can have significant impacts on the environment, including soil degradation, loss of biodiversity, and water pollution.
