Weathering that occurs by water in the desert is associated primarily with what?

Chemical weathering involves the decay and breakdown of the constituent minerals of the rock. It occurs primarily when there is a chemical reaction between the minerals and water, but it can also happen when the minerals react with air or with an invasive solution of some sort. The results can range from colour changes in the rock to its complete chemical decomposition. Mechanical weathering, by contrast, involves the breakdown of rock without any substantial chemical change in its constituent minerals. In practice, both types of weathering tend to operate in tandem, although their relative importance will differ depending upon particular local circumstances, such as water availability, rock type, and temperature regimes. http://uk.encarta.msn.com/encyclopedia_781533896/Desert_Features.html May 04 05, 3:27 AM
