Answer:
Ocean currents are the continuous, predictable, directional movement of seawater driven by gravity, wind (Coriolis Effect), and water density. Ocean water moves in two directions: horizontally and vertically. Horizontal movements are referred to as currents, while vertical changes are called upwellings or downwellings.They carry cold water from the poles to the equator and cool air over land. They move warm water from the equator to the poles and heat air over land.
