It is often (always?) said that if you view the movement of the 
continents backwards through time, you end up at a point where 
all the present land masses were one giant continent.  If this is 
true, then why was this the case?  It seems unlikely that when 
the Earth formed you ended up with all the high portions (above 
sea level) being in one mass and not spread evenly around.
