1. What is a wave and where do all ocean waves come from?

Wave is a water disruption that causes ripples that can be big or small

Waves occur because of the gravitational pull from the moon.

In science, a wave is defined as a transfer of energy. Ocean waves are caused by wind moving across the surface of the water. The friction between the air molecules and the water molecules causes energy to be transferred from the wind to the water. Waves are mostly caused and come from wind.
