Latin denudare "strip" Erosion.

The erosion of the earth's surface due to rain, frost, wind, running water, or other actions, and the consequent uncovering of the surface that was otherwise covered.

Denudation is the process by which the removal of material, through means of erosion and weathering, leads to a reduction of elevation and relief in landforms and landscapes. Exogenic processes, including the action of water, ice, and wind, predominantly involve denudation. Denudation can involve the removal of both solid particles and dissolved material.
