Question

select the correct answer. which gas is a major contributor to ocean acidification? ○ a. oxygen ○ b. sulfur dioxide ○ c. carbon dioxide ○ d. nitrogen

Explanation:

Ocean acidification occurs mainly due to the absorption of carbon dioxide (\(CO_2\)) by seawater. When \(CO_2\) dissolves in water, it forms carbonic acid (\(H_2CO_3\)), which increases the acidity of the ocean. Oxygen (\(O_2\)) is essential for marine life respiration and does not cause acidification. Sulfur dioxide (\(SO_2\)) can contribute to acid rain but is not the major gas for ocean acidification. Nitrogen (\(N_2\)) is relatively inert in this context and not a major contributor to ocean acidification.

Answer:

C. carbon dioxide
