Question

How can carbon be transferred between the atmosphere and Earth’s other spheres?

A. Oceans both absorb carbon from the atmosphere and emit carbon to the atmosphere, and – on an annual basis – oceans absorb more carbon than they emit.
B. The burning of fossil fuels is the only way carbon is transferred to the atmosphere.
C. The cryosphere is the largest source of carbon for the atmosphere, and very little carbon is transferred from the atmosphere back to the cryosphere.
D. Photosynthesis transfers carbon from the biosphere to the atmosphere and respiration transfers carbon from the atmosphere to the biosphere.

Answer 1

Carbon can be transferred between the atmosphere and Earth’s other spheres through processes such as photosynthesis, respiration, and the burning of fossil fuels. The oceans also play a role as a carbon sink.

Step-by-step explanation:

Carbon can be transferred between the atmosphere and Earth’s other spheres through various processes. One way is through photosynthesis, where plants in the biosphere take in carbon dioxide from the atmosphere and convert it into glucose. On the other hand, respiration releases carbon dioxide back into the atmosphere. Another way is through the burning of fossil fuels, which releases carbon dioxide into the atmosphere. Additionally, the oceans act as a carbon sink and source. They can absorb carbon dioxide from the atmosphere, helping to reduce its concentration, and also release carbon dioxide through various natural processes.
