The ultimate end-result is the formation of new materials that contributes to the creation of pores and fissures in the rocks, in turn, accelerating the disintegration action. Chemical weathering involves various processes and types of weathering. Here are the detailed aspects. This type of chemical reaction is highly common in igneous rocks. The reaction takes either the form of hydration or dehydration. Absorption of water into the rock pert…

Chemical Weathering. Chemical weathering is the breakdown of rocks because of the interaction of air, water or acid with the chemical composition of the rock. Oxidation occurs when oxygen reacts with minerals such as calcium and magnesium to form iron oxide. Iron oxide is reddish brown in colour and causes the decomposition of rock.
