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

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

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.
