Final answer:
Ocean currents affect temperature by transporting heat from one area to another. They can carry both cold and warm water, leading to cooling or heating of the air over land.
Step-by-step explanation:
Ocean currents have a significant impact on temperature by transporting heat from one area to another.
They can carry cold water from the poles to the equator, which cools the air over land.
In addition, they can move warm water from the equator to the poles, heating the air over land.
These temperature changes are important for shaping climates around the world.
