Chemical Weathering an overview ScienceDirect Topics
Nicholas P. Cheremisinoff Ph.D., in Groundwater Remediation and Treatment Technologies, 1997. Chemical Weathering. 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.
4 Types and Examples of Chemical Weathering
There are three types of weatheringmechanical, biological, and chemical. Mechanical weathering is caused by wind, sand, rain, freezing, thawing, and other natural forces that can physically alter rock. Biological weathering is caused by the actions of plants and animals as they grow, nest, and burrow.
