Waters pays an important role in chemical weathering. the carbon dioxide in atmosphere dissolves in rainwater and from carbonic acid and reacts with minerals in the rocks. the soluble minerals dissolve in water such as feedspar and potash absorb water and become a powderd mass similarily soluble minerals dissove and are removed , resulting in the breakup of the rocks . Rock salt, gypsum, and silica are examples of minerals theat are highly soluble and when rainfall falls they decompose.
