The process by which the Earth's surface is generally reshaped and lowered is known as denudation. Denudation involves the wearing away of the Earth's surface by various agents of erosion such as water, wind, ice, and gravity. Over time, these agents of erosion gradually remove or strip away the top layers of rock, soil, and other materials, causing the Earth's surface to become smoother and lower. Denudation can occur on a small scale, such as the gradual wearing away of rocks by a river, or on a larger scale, such as the formation of canyons or valleys by glaciers or tectonic activity.
