I am not going to answer this in depth due to the fact that it probably wouldn't fit on the page. I know that the magma core inside the earth has lots of magnetic 'power', and that it matches up wit the poles and compasses. Also, it makes sense with the possibility that the continents shifted due to the tectonic plates shifting which is evident by the today evidence of California 'falling'. If you do not know of this, look it up, and it fits with the idea that the continents shifted. I can hit any one of these topics if you would like something more detailed.
