The continuous directed motion that covers the whole planet of warm water moving toward the Earth’s poles and cool water returning to the equator is called:
A
ocean currents
B
jet streams
C
cells
D
trick question, there is no continuous directed motion of warm water moving toward the Earth’s poles and cool water returning to the equator.
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -Large rotating currents that start near the equator are called subtropical gyres. There are five main gyres: the North and South Pacific Subtropical Gyres, the North and South Atlantic Subtropical Gyres, and the Indian Ocean Subtropical Gyre.

Detailed explanation-3: -In the equatorial Pacific, the trade winds blow the North and South Equatorial Currents towards the west, while Ekman transport causes the upper layers to move to the north and south in their respective hemispheres.

Detailed explanation-4: -A warm current is moving away from the Equator toward the poles. The water in a warm current is warmer than the surrounding water.

Detailed explanation-5: -There are two main types of ocean currents: surface currents and deep ocean currents. Surface currents are driven by global wind systems that are fueled by energy from the sun.
