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?
I have seen the ocean with no wave action, looking like a sheet of glass. It was necessary to get out in the middle of it though.
The moon. If you've ever lived on the water you know what high, high tide means. Millions of years ago some chunk of something hit the earth and blew off and made the moon and it tilted the earth's axis and gave us seasons and that bit of the earth made the moon that gives us the gravity that we know. Science is your friend. You're typing on something that is less proven than evolution. Evolution is so proven that it's a fact. Sorta the way this quantum computer is a fact. The earth is 47 billion years old. Deal.
"origins" dating is full of "unproveable assumptions" ....if a world wide flood happened as the story of Noah as well as many cultures have in their histories, then all bets are off, because the "conditions" that the dating methods are counting on are now null and void. Deal.
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. :)
