Which of the following best describes the movement of heat energy in the global ocean?
an arrow representing wind
During the process of convection, water that was warmed by the sun loses heat. The water cools, becomes denser, and sinks.
Heat energy in warm surface currents is transported to areas near Earth’s poles.
upwelling
Warm water loses energy to its surroundings and cools.
differences in water density
surface winds, the Coriolis effect, and continental deflection
When water loses heat, it becomes denser and sinks.
How does convection cause ocean currents?
