Question 6 of 10
6. Question
Which of the following statements about ocean acidification is/are NOT CORRECT?
- Ocean acidification is the ongoing increase in the pH of the Earth’s oceans, caused by the uptake of carbon dioxide from the atmosphere.
- It increases the concentration of hydrogen ions and decreases the concentration of carbonate ions.
- Ocean acidification leads to seawater pH go well below 7.
