I can understand why Pangea broke up, because it was allowing the land to go to a lower energy state.
But why when Earth formed, was there one giant island on one side and water on the opposite side?
I was thinking that the formation of the moon must have happened not long after the Earth, so that the moons gravitation pull would cause land to bulge on the side closest to earth. But that means at that time, the Earths rotation must have been equal to the moons revolution, which is very possible since the moon is gradually moving away from us, hence changing its period of revolution.
Any Legitimate reasons are greatly appreciated.
And another thing. Is it just a coincidence that the Moons period of rotation is equivalent to its period of revolution?
