Answer:
The options are
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 answer is A.The density of ocean water might change.
Step-by-step explanation:
The ocean's surface temperature was observed to be increasing. Density has a relationship with temperature. It is known that density has an inverse relationship with temperature. As temperature increases the density decreases and vice versa.
Since the oceans surface temperature was increasing then there would be a likely change in the density of the water in the ocean.
