Question

Quizplus · Accepted Answer

The sun is the ultimate source of energy for all the earth's phenomena, including the oceans. The sun heats the surface of the ocean, creating temperature differences, leading to the movement of water and the formation of ocean currents. The wind and tides also affect ocean currents but are not the ultimate source of energy. Weather is a short-term phenomenon that can affect ocean currents but is not the ultimate source of energy for them.
