Question

Q. Which of the following factors will lead to an increase in the surface water salinity of the ocean?

Select the correct answer using the code given below:

• A. 1 only
• B. 1 and 2 only
• C. 2 and 3 only
• D. 1, 2 and 3

Answer 1

The correct option is B 1 and 2 only

Explanation:

• Statement 1 is correct. Evaporation removes water from the ocean, leading to an increase in salinity.
• Statement 2 is correct. The formation of glaciers removes water from the ocean, leading to an increase in salinity. On the other hand, the thawing of glaciers adds freshwater to the ocean, leading to a decrease in salinity.
• Statement 3 is incorrect. Rivers add fresh water into the ocean, leading to a decrease in the salinity of the ocean.
