Things I find interesting. The moon's gravity pulls the ocean away from the surface of the earth to create one of our daily tides but the other tide is a result of the earth not rotating directly on it's access. This wobble is a result of the gravitational effect of the earth on the moon. Bit like a hammer thrower at the olympics. The earth leans away from the moon. So while the water is being pulled off one side of the earth by the moon, water is being flung off the other side of the earth by centrifugal force. Bit like swirling your coffee around in your cup.

And as usual I could have it all wrong again.

Did you know that when the moon use to rotate, the earths gravitational force on it resulted in the surface of the moon lifting up. Bit like a ripple moving across the surface. Well so they say.
