What I don't get is why doesn't the water on the surface just drain away into the center of the earth. The water on the surface of the earth is really thin. It is only five miles at the deepeest point and that is nothing compared to how far it is to the center of the earth. If the earth where a basketbal the oceans would be a fine mist on the surface.
So why doesn't the water just drain through the cracks?
