Table 3 lists the main reservoirs of carbon in the Earth's crust and surface environments. 5) Based on Table 3, what proportion of carbon is contained in sedimentary rocks? 6) Increasing levels of CO in our atmosphere and consequent global warming are one of the most important issues facing our society. What are at least three ways that humans are causing the movement of carbon into the atmospheric "reservoir" from other storage places on Earth? Table 3.
