One of the most well-known solution weathering processes is carbonation, the process in which atmospheric carbon dioxide leads to solution weathering. Carbonation occurs on rocks which contain calcium carbonate, such as limestone and chalk.hemical weathering changes the composition of rocks, often transforming them when water interacts with minerals to create various chemical reactions. Chemical weathering is a gradual and ongoing process as the mineralogy of the rock adjusts to the near surface environment.
neither really happens first.. Erosion is the process of earth being moved from one place and being deposited at another. Weathering is the breaking down of structures into pieces that can then be taken away. So, in the cases where there is weathering, weathering would occur first then erosion. Weathering, the wearing down of rocks or soil, happens before erosion, the removal of rock or soil. neither really happens first..
