The carbon cycle, A ‘biogeochemical’ cycle What is biogeochemistry? The study of the  bio logical,  geo logical and  chemical   processes that cycle elements  and molecules in natural  systems.   Carbon is found in the  atmosphere, ocean, biological  organisms, and geological  deposits (e.g. limestones, coal)

Volcanism and weathering Volcanic emissions of CO 2  make rain water  slightly acidic, leads to weathering of rocks, and  carbon eventually returned to the sediments Draw figure of volcanism-weathering loop. Responsible for the long-term equilibrium of  atmospheric carbon dioxide greater volcanic input of CO balanced by enhanced  weathering Relevant on million-year timescales
