Denudation is the collective term for processes that cause the wearing away or removal of rock and soil from the Earth's surface. It is a fundamental process in geomorphology, the study of the physical features of the Earth and the processes that shape them. Denudation can occur through various mechanisms, including weathering, erosion, and mass movement.

Weathering is the breakdown of rock into smaller particles without significant movement. It can be physical, where rocks are broken down by temperature changes, frost action, or plant roots, or chemical, where rocks are dissolved by water or acids. Erosion, on the other hand, involves the transportation of these broken-down particles by agents such as water, wind, or ice. Mass movement refers to the downhill movement of rock, soil, and other materials under the influence of gravity.

Denudation is influenced by several factors, including climate, topography, and vegetation. In areas with high rainfall and temperature variations, weathering and erosion are more pronounced. Steep slopes are more susceptible to mass movement, while flat areas are more prone to erosion by water. Vegetation can also play a significant role, as plant roots can help stabilize soil and reduce erosion.

Denudation is a continuous process that shapes the Earth's surface over time. It is responsible for the formation of many landforms, such as valleys, canyons, and cliffs. Understanding denudation is crucial for various fields, including geology, environmental science, and civil engineering, as it helps in predicting and mitigating natural hazards such as landslides and floods.
