Multiple Choice

Which of the following is the likely link between ocean acidification and increased anthropogenic emissions of carbon dioxide (CO2) ?

• A)Oceans may absorb up to 50% of rising concentrations of rising carbon.When dissolved CO2 mixes with saltwater,carbonic acid forms (H2CO3).
• B)Atmospheric CO2 combines with atmospheric moisture forming a light carbonic acid (H2CO3)that is precipitated over the world's oceans.
• C)Increased photosynthetic activity in phytoplankton resulting from increased atmospheric CO2 concentrations results in acidification due to a complex chemical reaction during plant decay.
• D)Thermohaline circulation exchanges carbon between surface dissolved organic carbon and deep layers of dissolved inorganic carbon.
