Why are there waves in the ocean?

Answer: Wind friction on water surface

Wind friction on water surface ✓ — Correct! Wind blowing across the ocean transfers energy to the water through friction. This creates ripples that grow into waves. Wave size depends on wind speed, how long it blows, and the distance (fetch) over which it blows. The water itself doesn't move forward - energy does! Only the wave form travels; water particles move in circular orbits.

Moon pulls water up and down — Wrong. While the moon does affect ocean water, it causes tides (rise and fall over hours), not waves (which occur every few seconds). Tides are different from waves. Regular ocean waves are caused by wind, not lunar gravitational pull.

Ocean floor pushes water — Wrong. The ocean floor doesn't push water to create waves. Waves are surface phenomena caused by wind. However, underwater earthquakes can create special waves called tsunamis, but regular ocean waves come from wind friction on the surface.
