Question 25

This diagram demonstrates why the ocean is a large carbon sink.

An increase in the amount of carbon dioxide in the atmosphere can cause atmospheric temperatures to increase. Which statement explains how this could affect the ocean as a carbon sink?

Accepted Answer

Less carbon dioxide would be dissolved in the ocean because increasing atmospheric temperatures would cause ocean temperatures to increase.

Answer

Less atmospheric carbon dioxide would be available to phytoplankton.

Answer

Dissolved carbon dioxide gas in the ocean would increase because surface winds would cause a deeper circulation pattern, making more room for the gas.
