What causes ocean waves?

Waves are caused by energy passing through the water, causing the water to move in a circular motion.

Looking out at the ocean, you often see a seemingly infinite series of waves, transporting water from one place to the next. Though waves do cause the surface water to move, the idea that waves are travelling bodies of water is misleading.

Waves are actually energy passing through the water, causing it to move in a circular motion.
