Carbonation is the dominant chemical process in limestone weathering. Rainwater combines with carbon dioxide from the atmosphere to form weak carbonic acid, which reacts with calcium carbonate in limestone to form calcium bicarbonate that dissolves in water. This process creates distinctive karst landscapes with features like sinkholes, caves, and limestone pavements.
