Question

What makes the water in the sea move?

Answer 1

Tides contribute to coastal currents that travel short distances. Major surface ocean currents in the open ocean, however, are set in motion by the wind, which drags on the surface of the water as it blows. The water starts flowing in the same direction as the wind.

Answer 2

Waves are created by energy passing through water, causing it to move in a circular motion. The ocean is never still. ... Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest.
