Concept:An ocean wave is a continuous circulatory movement of surface water caused mainly by wind.
Explanation:Wind blowing across the ocean surface transfers energy to the water.
Water particles then move in a circular or orbital path as the wave passes.
This circular motion is why a wave is described as a circulatory movement.
The movement continues as long as the wind keeps supplying energy to the sea surface.
A current moves water continuously in one direction, not in a circular pattern.
Ripples are only tiny, localised waves, common on small water surfaces.
A tsunami is a single large, destructive wave caused by an underwater disturbance such as an earthquake.
Therefore, the correct answer is waves.
Answer:C. Waves
