Jessica Harvey Ocean Acidification

Approximately what fraction of atmospheric carbon dioxide (CO2) is absorbed into the ocean?

• 1/4

• 1/3

• 1/2

• 2/3

What is the primary chemical change that defines ocean acidification?

• The ocean becoming more basic.

• The ocean becoming more acidic.

• The ocean's temperature increasing.

• The ocean's salinity decreasing.

When carbon dioxide (CO2) dissolves in seawater, what compound is primarily formed, leading to ocean acidification?

• Methane

• Carbonic acid

• Sulfuric acid

• Nitric acid

How does ocean acidification primarily affect calcifying organisms like shellfish and coral?

• It increases their ability to form calcium carbonate skeletons.

• It causes the erosion of their calcium carbonate shells and skeletons.

• It makes them grow larger and faster.

• It has no significant impact on their shells.
