Answer:
Option (A) and (D)
Explanation:
Ocean gyres are the system of oceanic water circulation that occurs due to the prevailing wind patterns and the forces that are initiated by the rotation of the earth. This continuous motion of ocean gyres forms a conveyor belt that circulates the water from the equatorial to the polar regions in both the hemisphere. It maintains the overall temperature, amount of nutrients, and the salinity of the ocean water.
These ocean currents are diverted towards the right by the Coriolis force that occurs due to the earth's rotation.
The ocean in the equatorial region is warmer than the water at the higher latitudes. It is because of the higher amount of sunlight that falls in this region. At higher latitudes, the temperature is relatively low and there the waters are much colder.
These ocean currents circulate in both the hemisphere, carrying the hot and warm water from the equator to the polar region and in return, carries the cold water from the polar to the equatorial region.
Thus, it can replace a hot climate by a colder one and a cold climate by a hotter one.
Hence, the correct answers are an option (A) and (D).
