Pole shift is generally believed to be due to the gradual redistribution of mass in outer Earth's mantle and the crust. Our planet is most stable when its most massive parts are farthest from its spin axis; that is, on the equator. If mass redistribution were to occur somewhere on an otherwise uniform Earth, the planet would reorient itself so that the mass concentration would move to the equator. Over the past century, the north pole moved about 33 feet toward eastern Canada. Most geophysicists believe the movement is due to true polar wander (TPW), or a shift of the Earth's entire mantle and crust relative to Earth's core.
