corrosion"The gradual deterioration of material by chemical processes, such as oxidation or attack by acids; if caused by an atmospheric effect, a form of weathering.
Erosion is distinct from weathering, for the latter does not necessarily imply transport of material. Where human agency has increased erosion beyond the normal geologic rate, it is termed accelerated erosion.
The process of weathering breaks down rocks and soils into smaller fragments and then into their constituent substances.
Erosion Wearing away of the lands by running water, glaciers, winds, and waves, can be subdivided into three process: Corrasion, Corrosion, and Transportation. Weathering, although sometimes included here, ...
Natural origins include salt particles from sea spray and clay particles as a result of weathering of rocks. Aerosols can also originate as a result of man's activities and in this case are often considered pollutants.
Weathering, although sometimes included here, is a distant process which does not imply removal of any materialEruptiveIn solar-terrestrial terms, ...
