What is the relationship between increased carbon in the ocean and increased carbon in the soil? How else might carbon be transferred to soil?
Using the data generated by the simulation, determine the mathematical relationship between the percentage increase in fossil fuel consumption and the increase in atmospheric carbon. Is the relationship linear?

a)
Earth's carbon cycle is dominated by the ocean, which absorbs 50% of the CO2 released into the atmosphere by human activity. Carbon settling to the ocean bottom can eventually be stored for millions of years.
