The chemical weathering is the process in which the rocks and minerals are break down by the chemical reaction. Then, it lead to the decomposition of primary minerals into other minerals.
Weathering is the chemical and physical process that change the state of chemical process in the surface of earth. Chemical weathering dissolve by the chemical process which basically form the residual materials.
This process cause rust when the iron react with the oxygen in the rocks and then it form iron oxide.
Chemical weathering is the set of chemical reactions that alter the minerals that make up rocks. It is characterized by chemical transformations arising from the pressure and temperature differences of the rocks. The environment in which rocks form is often different from the earth's surface. Thus, when these rock formations surface, they encounter conditions and elements such as water and oxygen that make their minerals chemically unstable. To stabilize, they undergo chemical transformations, altering their composition. In these cases, it is possible to observe the modification of soils or rocks, when they change their appearance or composition, becoming wetter or drier, for example.
