Detailed explanation-1: -Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth’s surface. Without currents in the ocean, regional temperatures would be more extreme-super hot at the equator and frigid toward the poles-and much less of Earth’s land would be habitable.

Detailed explanation-2: -The water that does make it to the equator often turns to flow along the equator. The part that does cross the equator trails off into swirls known as eddies. When currents come up against boundaries, such as continents, they can overcome the forces that keep them otherwise bound to one hemisphere, but not for long.

Detailed explanation-3: -Temperature decreases progressively from equator towards the poles because it receives less sunlight. As we go away from equator the temperature decreases and in poles it becomes very little or none.

Detailed explanation-4: -By moving heat from the equator toward the poles, ocean currents play an important role in controlling the climate. Ocean currents are also critically important to sea life.
