Question

Which of the following is a major cause of increasing ocean acidification?
A)eutrophication
B)construction of dams and levees
C)rising sea level
D)rising levels of CO2
E)decreasing dissolved oxygen

Accepted Answer

Rising levels of CO₂ (carbon dioxide) is the major cause of increasing ocean acidification. When CO2 dissolves in seawater, it reacts with water molecules to form carbonic acid, which lowers the pH of the water and makes it more acidic. This can have harmful effects on marine organisms and ecosystems.
