Document Summary

Reservoir is what the box is -- the atmosphere is 740. 3 box model of carbon cycle: fast cycle. 4 years is the about the turnover time for co2 in the atmosphere. Today, adding deep ocean (medium fast), and looking at 2 box model of carbon cycle: slow cycle (rocks) What are the effects of moving c from ******** 2-box model of carbon cycle: slow carbon cycle questions. As in rain, h20 +co2 -> h2co3. H2o +co2 + casio3 -> caco3 +sio2 + h20. Calcium carbonate is soluble, flows out in rivers. What is the residence time of a co2 molecule: Fossil fuels are making the slow carbons fast . Current human emissions are about 10 gt. 10 gt from slow cycle and adding it to fast cycle (0. 1 to 10 gt) Although half our co2 emissions are taken up by the ocean and land sink.
