剥蚀作用是将分化产物从岩石上剥离下来，同时也对未风化的岩石进行破坏，不断改变着岩石的面貌。

In geology, denudation is the long-term sum of processes that cause the wearing away of the Earth’s surface by moving water, ice, wind and waves, leading to a reduction in elevation and relief of landforms and landscapes. Endogenous processes such as volcanoes, earthquakes, and plate tectonics uplift and expose continental crust to the exogenous processes of weathering, erosion, and mass wasting.
