The ocean absorbs carbon dioxide directly from the atmosphere. how does co2 absorption affect the ocean? a.) the acidity of ocean water increases. b.) coral reefs expand, and coral skeletons harden. c.) ocean water becomes colder and denser. d.) saline (salty) ocean water turns into freshwater.

CO2 absorption affects the ocean because;

A.) The acidity of ocean water increases

The more carbon dioxide that people pumped into the atmosphere by burning fossil fuels, the more the oceans would absorb.

The ocean would continue to soak up more and more carbon dioxide until global warming heated the ocean enough to slow down ocean circulation.

a. the production of carbon dioxide through the process of photosynthesis
