How are waves formed:

Joshua Wigley, the 14 year old son of Eden WaterWise Instructor Liza, was interested by the question ... How are waves formed? ... and did some research. This is how he explained it:It is the energy in the wind that makes the water in the ocean move; this is also what creates waves. It is gravitational pull of the sun and moon that changes the tides. The ocean floor (sand) also moves. The water moves the sand.
