Quizplus · Accepted Answer

The diagram shows that the largest pool of carbon is in Rocks and Fossil Fuels, followed by the deep ocean waters. The atmosphere and soils also contain significant amounts of carbon, but not as much as rocks and ocean waters. Sand and detritus are small pools and contribute very little to the world's carbon storage.
