To put it into simple terms, a wave is a travelling disturbance and it is up to human beings to process the disturbance and interpret them. Waves transport energy and not water. In a wave motion, energy is transmitted from one point to another without actually moving the water. They move through the water in a circular motion as the wave passes through. Like any other wave, a water wave appears to move up and down in a pattern but deep down, the water particles move in smaller circles than particles near the surface. These movements in small waves only move bits of sand. However, in larger waves, it can wash away everything on its path.
