Multiple Choice

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?

• less atmospheric carbon dioxide would be available to phytoplankton

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

• less carbon dioxide gas would be contained in the ocean because increasing precipitation would dilute the carbon entering the ocean

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