Studies show that the ocean's surface temperature is increasing. Which of the following is a possible consequence?

A. The density of ocean water might change.

B. Low tides might disappear.

C. Earth's rotation might change direction.

D. Gyres might change direction.

The statement that "Studies show that the ocean's surface temperature is increasing" has the a possible consequence as the density of ocean water might change. The answer is letter A. The difference in density of the ocean layer is divided into three: surface, middle and bottom. About 2% for the surface, 18% for the middle and 80% for the bottom. Oceans, rivers, ponds, lakes, waterfalls represent the water. These are where most of the organisms that lives on water is located. It is said that earth consists of 70% of water and the rest are land. Air is the reason why all of the microorganisms living on earth are alive because of its composition, 21% oxygen and 79% nitrogen. And life, the organisms that dwells on earth.

The correct answer is A.
