Question 7: Which reservoir stores the most carbon as measured by Gt? (1 point) Responses Fossil Fuels Fossil Fuels Rocks Rocks Oceans Oceans Atmosphere Atmosphere Question 3 Question # 8: Why does Earth's atmosphere contain a relatively small amount of carbon dioxide compared to other carbon reservoirs like the ocean and rocks? (1 point) Responses Most atmospheric CO2 dissolves into the ocean due to ocean circulation patterns Most atmospheric CO2 dissolves into the ocean due to ocean circulation patterns Carbon dioxide molecules are too heavy to stay in the air for long periods Carbon dioxide molecules are too heavy to stay in the air for long periods The atmosphere can't hold as much CO2 because it is too small

Question 7: The reservoir that stores the most carbon as measured by gigatons (Gt) is Rocks. While fossil fuels and oceans also store significant amounts of carbon, geological formations (rocks) contain the largest amount of carbon in the Earth's system.

Question 8: The reason Earth's atmosphere contains a relatively small amount of carbon dioxide compared to other carbon reservoirs like the ocean and rocks is: Most atmospheric CO2 dissolves into the ocean due to ocean circulation patterns. The oceans act as a major sink for carbon dioxide, absorbing it from the atmosphere.
