The ranking order is as follows: 1) Marine biomass, 2) Ocean water, 3) Rocks and fossil fuels, 4) Soil, 5) Atmosphere and 6) Plant biomass.
Their carbon capacity in billions of metric tons is as follows:
1) Marine biomass - 66 - 100 million metric tons
2) Ocean water - 38000 to 40000 metric tons
3) Rocks and fossil fuels - 4000 tons
4) Soil - 1500 to 1600 tons
5) Atmosphere - 766 tons
6) Plant biomass - 540 to 610 tons

1.Which of the following would act as a negative feedback loop? Select one: a. Increased evaporation of water, which results in more clouds. b. Higher temperatures, which increase release of dissolved carbon dioxide from the oceans. c. Increased absorption of carbon dioxide by the oceans, which results in ocean acidification. d. Melting of polar ice, which alters ocean circulation patterns. 2.The sawtooth pattern of increasing and decreasing carbon dioxide concentrations observed by Charles Keeling at Mauna Loa Observatory was a...

DESIGN OF A STEAM POWER PLANT IN THE AGE OF CARBON TAXATION, Due: Aug. 15, 2018 Introduction: As the world continues to spew unprecedented amounts of carbon dioxide into the atmosphere as a result of combustion of fossil fuels, many countries are considering imposing a "carbon tax." A carbon tax is a tax on the carbon emissions, which are currently emitted for "free." The tax would effectively raise the cost of burning fossil fuels in an amount proportional to the...
