GEOLOGY

Detailed explanation-1: -Cold currents bring cold water into warm water areas (from high latitudes to low latitudes). Cold ocean currents are masses of cold water moving from high latitude towards the equator absorbing the heat received in the tropics thus cooling the air above.

Detailed explanation-2: -Warm ocean currents originate near the equator and move towards the poles or higher latitudes while cold currents originate near the poles or higher latitudes and move towards the tropics or lower latitude.

Detailed explanation-3: -Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth’s surface.

Detailed explanation-4: -Cold currents are large masses of cold water that move towards the equator. Flowing from higher altitudes to lower ones. They absorb the heat they receive in the tropics. As a result, they cool the air above them.

Detailed explanation-5: -At high latitudes, ocean waters receive less sunlight – the poles receive only 40 percent of the heat that the equator does. These variations in solar energy mean that the ocean surface can vary in temperature from a warm 30°C (86°F) in the tropics to a very cold-2°C (28°F) near the poles.
