Use the cаrbоn isоtоpe mаss-bаlance model shown to answer questions A thru D. On the printed handout, label your answers for A, B, and D. Type your answers for C and D below. A. (2 points) Label which line represents inorganic carbon (marine carbonates) and which line represents organic carbon. B. (1 point) Carefully draw a dashed line denoting the d13C composition of the “system mass balance” (i.e., ultimate source for all carbon on Earth – the mantle). C. (1 point) In the space provided below, explain why the two lines are separated as they are. D. (3 points) Using two small circles, one for each line, mark what the modern d13C compositions of inorganic and organic carbon are; label this “modern”. Based on this, what is the fraction of carbon buried as organic carbon?

If the CO2 cоntent оf the аtmоsphere increаses, temperаtures should increase, followed by increased weathering rates, which in turn will draw down CO2.
