Gravitational forces from the moon as well as wind.
so we would have something to bring drama and excitement into our lives. Are the waves annoying you for some reason?
The tides and waves are put into motion by the gravitational pull of the moon and the influences of the wind.
The moon of course. No moon, no waves.
and then what would all the surfer folk do
wow.. did they not teach you anything in science class..? you know tides, moon phases, that sort of stuff..
so we can surf...otherwise why have an ocean?
Wind causes Waves. :)
