A wave is the rhythmic movement that carries energy through space or . matter. Waves are generated by wind flowing over the water . surface. As a wave passes, water moves up and down in a circular pattern – returning to its original position. 1. Water on Mars (. SciShow. ). https://www.youtube.com/watch?v=djcszDBsQkE.
