Weathering of rocks impacts climate change

Physorg: The carbon dioxide in the atmosphere dissolves in rainwater forming carbonic acid, which, once in contact with rocks, slowly dissolves them. This atmospheric carbon is then transported by rivers into the oceans, where it is trapped for several thousand years, before returning to the atmosphere or alternatively being stored in marine sediments or in corals.
