# Does the Earth rotate vertically too?

We know that the earth has seen several Ice Ages.

And we know the Earth's magnetic poles seem to flip once in a while.

Could all of this be explained by a once every 250 Million Years or so the Earth actually rotates head over heels, so to speak?

For a flip over with angular momentum conservation, very drastic things would have to happen.The angular momentum of the earth about an axis vertical to the current axis is very small ( there exists precession of the axis). Let suppose it zero. For the north pole to become the south pole and vice verso the liquid core of the earth would have to take up that angular momentum and as Rod says the geological upheavals would be great. Also whence would come the original impetus for this flip? –  anna v Jan 7 '14 at 9:54
