What are the Largest Reservoirs of Carbon Dioxide and Heat

Question

What are the largest reservoirs of carbon dioxide and heat on Earth?
A) the atmosphere
B) the oceans
C) animal bodies
D) fossil fuels

Accepted Answer

The oceans are the largest reservoirs of both carbon dioxide and heat on Earth. The ocean's surface absorbs about 30 percent of the carbon dioxide that is released into the atmosphere from human activities, and the deeper layers of the ocean also store significant amounts of carbon dioxide. Additionally, the ocean stores about 90 percent of the excess heat that is trapped on Earth due to greenhouse gas emissions.
