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.
Weathering is simply the physical breakup (disintegration) and chemical breakdown (decomposition) of a rock. The two processes work in concert to weaken and tear apart the rocky foundation so it can be more easily eroded.Each processes increases the effectiveness of the other.hemical weathering (decomposition). Processes of Chemical weathering. Chemical weathering breaks down minerals into different chemical components. Rocks, such as rock salt and limestone dissolve entirely, this is known as congruent solution.
