WebChemical weathering occurs when the breakdown of rock results from chemical change in the rock, or the when the rock is dissolved away. The rate of these chemical reactions is affected by climatic conditions such as precipitation and temperature, with water and warmer temperatures increasing the rate. WebWeathering is usually confined to the top few meters of geologic material, because physical, chemical, and biological stresses generally decrease with depth. Weathering of rocks occurs in place, but the disintegrated weathering products can be carried by water, wind, or gravity to another location (i.e., erosion or mass wasting).
