Chemical Weathering - an overview | ScienceDirect Topics

Chemical weathering, on the other hand, is an actual change in composition as minerals are modified from one type to another. Many, if not most of the changes are accompanied by a volumetric increase or decrease, which in itself further promotes additional chemical weathering. The rate depends on temperature, surface area, and available water.
