How Is Ocean Acidification Possibly Linked to Increased Anthropogenic Emissions

question 125

Multiple Choice

How is ocean acidification possibly linked to increased anthropogenic emissions of carbon dioxide (CO₂) ?

• A)Oceans may absorb much of the rising concentrations of rising carbon,as dissolved CO₂ mixes with water to form carbonic acid (H₂CO₃).
• B)Thermohaline circulation exchanges carbon between surface dissolved organic carbon and deep layers of dissolved inorganic carbon.
• 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)Atmospheric CO₂ combines with atmospheric moisture forming a light carbonic acid forms (H₂CO₃),that is precipitated over the worldʹs oceans.
