When carbon dioxide is absorbed by seawater, chemical reactions occur that reduce seawater pH, carbonate ion concentration, and saturation states of biologically important calcium carbonate minerals.

• Coral bleaching

• ocean acidification

• oceanography

• ocean aging

What is ocean acidification and how is it related to the carbon cycle?

• It is the process of oceans becoming more basic due to decreased carbon dioxide levels

• It is the process of oceans becoming more acidic due to increased carbon dioxide levels

• It is the decrease in ocean temperatures due to reduced carbon dioxide in the atmosphere

• It is the increase in ocean temperatures due to increased carbon dioxide in the atmosphere

Which of the following best describes what you see in the graph?

• Ocean acidification is decreasing because carbon dioxide levels in the atmosphere are increasing.

• Ocean acidification is getting worse and could cause many coral reefs to die if not reversed.

• Ocean acidification is getting better because global carbon dioxide levels are decreasing.

• Ocean acidification is increasing which is beneficial to coral reefs and shellfish.
