Do Sea Waves Really Move?
Big and small waves appear on the sea because of the winds that form ripples on the water surface. It appears as if the water at the surface of the sea is moving along with the waves. But in reality it moves only up and down in the same spot!
When a wave passes over a particular spot on the sea, the water at the surface rises, then falls back when the wave has passed. The wave itself moves along, but the water itself stays where it is, bobbing up and down with the waves.
