Question

which process is responsible for lowering the oceans pH due to the absorption of excess carbon dioxide?
1)Ocean circulation
2)Ocean acidification
3)Ocean pollution
4)Ocean desalination

Answer 1

The process responsible for lowering the ocean's pH due to the absorption of excess carbon dioxide is **2) Ocean acidification**. When carbon dioxide (CO2) is absorbed by seawater, it reacts with water to form carbonic acid, which increases the acidity of the ocean and lowers its pH.
