Question

the model shows average carbon storage in some reservoirs during the years 2000 to 2005. how does burning fossil fuels affect the size of carbon reservoirs? choose \increase\ or \decrease\ to describe the change to each reservoir. reservoir change in size of reservoir atmosphere increase decrease ocean increase decrease geological reservoirs increase decrease units = pg c

Explanation:

Burning fossil fuels releases carbon - stored in geological reservoirs into the atmosphere. Some of this carbon may then be absorbed by the ocean. So, the atmosphere's carbon reservoir increases as carbon is released into it. The ocean's carbon reservoir may increase as it takes up some of the extra atmospheric carbon. The geological reservoirs decrease as the carbon stored in them is released through burning.

Answer:

Atmosphere: Increase
Ocean: Increase
Geological reservoirs: Decrease
