different chemical composition and poorer physical constitution. The process: Chemical change in the nature of rock takes place in the presence of moisture containing many active gases such as CO2‚ N2‚ H2‚ and O2. Rocks are made up of minerals. All the minerals in a rock are not in chemical equilibrium with the atmosphere around them. Chemical weathering is essentially a process of chemical reactions between the surfaces of rocks and the atmospheric gases. This process takes place so as to establish
