How Do ‘Waves’ Travel Across the Ocean?

Waves are like messages sent across the sea. Imagine you're on a boat in the middle of the ocean, when someone throws a stone into the water nearby, it sends out ripples that reach your boat. Waves work in the same way: energy from the wind creates them, and they travel far across the ocean without needing the same wind to follow all the way.
