7 分Water and carbon cycles as natural systems
The magnitude of water and carbon stores varies significantly across different scales.
(a) Compare the residence times of water in the cryosphere and the atmosphere, explaining how these differences influence the global water cycle. (3)
(b) Explain how the process of carbon sequestration in the oceans acts as a long-term store in the carbon cycle and the potential impact of rising ocean temperatures on this process. (4)
