erosion

Chemical Engineering

The physical removal of material from a surface by mechanisms that exclude chemical attack. The usual phenomenon that causes erosion is impingement by either liquid droplets or entrained solid particles. If there are no corrosive substances present, then in many cases, the most common mechanism for material damage due to erosion is impingement by solid particles. Compare corrosion.

Geology and Earth Sciences

1. The part of the overall process of denudation that includes the physical breaking down, chemical solution and transportation of material.
2. Movement of soil and rock material by agents such as running water, wind, moving ice, and gravitational creep (or mass movement). See bubnoff unit.

Geography

The removal of part of the land surface by wind, water, gravity, or ice. These agents can only transport matter if the material has first been broken up by weathering. Some writers use a very narrow interpretation of the word, claiming that erosion refers only to the transport of debris; see Stallard in P. Hancock and B. J. Skinner, eds (2000). If so, denudation would be the correct term for the weathering as well as the transport of rocks.
Primary erosion is the initial in situ erosion of rock, regolith, or soil.
