2. Wind Produces Waves (C102)

In the investigation you observed that wind produces waves. In fact, most waves are caused by wind. When wind blows over the surface of a body of water, it causes the surface of the water to move with it. Because water moves more slowly than air, the water piles up, forming a ripple. The wind then pushes on the side of the ripple, making it grow in height, and turning the ripple into a wave.
