Oxidation in weathering
WebMinerals weather chemically when they react with air and water. In these processes some minerals dissolve and others combine with atmospheric components (mainly water, oxygen and carbon dioxide) to form new minerals. The specific reactions include solution, oxidation, hydration and hydrolysis. WebMar 22, 2024 · 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.
