Why can oceanic absorption of atmospheric CO₂ be considered a feedback component of the Earth system?
Answer and explanation
Correct answer: Because oceans can partly regulate the amount of atmospheric carbon
The governing concept is the carbon cycle and Earth-system feedback. Oceans exchange carbon dioxide with the atmosphere and dissolve a substantial fraction of emitted CO₂; physical mixing and biological processes can move some carbon into deeper water. This changes atmospheric carbon and can influence temperature-related processes, so A is correct. B, C and D describe no valid oceanic role in the carbon cycle.
