1: Explain how individual water molecules move in a wave.

Explanation:

Individual water molecules move up and down but they do not move forward or backward. As a wave passes, water particles moves in circular motion. Deeper water particles moves in a smaller circles than those near the surface. The wind affects the water at the surface than it affects the deep water.

Within a wave, individual water molecules move in circles that get smaller with depth and eventually stop altogether. ... The vertical distance between the crest and the trough is the wave height. The horizontal distance between two adjacent crests or troughs is known as the wavelength.
