The oceans absorb carbon through three processes that draw atmospheric carbon dioxide into the oceans: the physical carbon pump, the biological carbon pump and the carbonate pump. In which scenario would a carbon sink be the result of the physical carbon pump mechanism?
Responses
A The movement of CO2 into and out of the ocean is fairly equal.The movement of CO 2 into and out of the ocean is fairly equal.
B More more CO2 is diffusing out to the atmosphere than is diffusing into sea surface water.More more CO 2 is diffusing out to the atmosphere than is diffusing into sea surface water.
C More CO2 is diffusing into sea surface water than is diffusing from sea surface water out to the atmosphere.More CO 2 is diffusing into sea surface water than is diffusing from sea surface water out to the atmosphere.
D More CO2 diffuses and dissolves in colder sea surface water and less CO2 diffuses and dissolves in warmer water.More CO 2 diffuses and dissolves in colder sea surface water and less CO 2 diffuses and dissolves in warmer water.
