What was the impact of having all the landmass in one place.

The following link provides a complete list of topics on this forum:


I was looking at several sources regarding Pangaea (as it was circa 220 million years ago) and would like to know what impact, having almost all the landmass together (above the surface of the water) in one position, would have had on the Earth's rotation.

We know that the Chandler wobble is caused by equatorial bulges and other imperfections in the earth's distribution of matter but would having all the land mass on one side of the planet 220 million years ago have caused enough of a wobble to break up of the surface into the tectonic plates we see today?

Would the 'vibration' of this uneven distribution have caused the origin of plates, or is there another cause?

Further, if the movements of the plates is something to do with the rotation of the earth causing the surface to 'balance out', does this mean that the plates will eventually slow down and reach some kind of equilibrium?
