Did the concentration of land mass of pangea cause the earth to wobble in its orbit?

Answer 1

It didn't happen when Pangea existed more then normal. This is because Pangea was places stenched pole to pole. Geologist do think that it might have happen during the Precambrian and might have caused the mega climate change with Rodina.

Answer 2

The amount of mass given by the land masses is neglibable. Remember, we're only really talking about the land above the water, since the 'missing' land is replaced by water. The majority of the Earth's mass is in the center. Our thin crust is a fraction of a percent of the mass. The Earth actually wobbled less during the pangea period because the moon was closer. Due to tidal friction, the moon is leaving our orbit. As it leaves, the wobble of the Earth increases. So, since the moon was closer during that time, the wobble was significantly less.

Answer 3

Land masses can be thought to generally float much like ice floats on water. Sometimes mountains get pushed up but forces are not in equilibrium. If continental glaciers cover the land, it will depress the land down and when they melt the land springs back in isostatic rebound.

Answer 4

No ... not at all.
