weathering

n. effect of weather; process by which exposed rock is disintegrated and decomposed by atmospheric agents or water (Geology); material used for weather strip

v. expose to atmospheric conditions; become worn by exposure to the weather; overcome, stand; to pass to the windward of a point (Sailing)

Weathering is the decomposition of rocks, soils and their minerals through direct contact with the Earth's atmosphere. Weathering occurs in situ, or "with no movement", and thus should not to be confused with erosion, which involves the movement and disintegration of rocks and minerals by processes such as water, ice, wind and gravity.

of Weather
  

(n.)
The action of the elements on a rock in altering its color, texture, or composition, or in rounding off its edges.
  

The process by which exposure to atmospheric agents, such as air or moisture, causes rocks and minerals to break down. This process takes place at or near the Earth's surface. Weathering entails little or no movement of the material that it loosens from the rocks and minerals. See also erosion
