Question

why are earth's poles changing position?

Answer 1

The earth's axis of rotation is not changing:  It is the magnetic poles that change.  They move up to 15 km per year, within about 25 degrees of the axis of rotation (true north), and the magnetic field of the earth varies with time and place.  at irregular intervals the magnetic field reverses itself, and the north magnetic pole becomes the south magnetic pole.

Because of plate tectonics and 'continental drift, through time different parts of the world have been located over the polar regions and this is called polar wander - the poles are not wandering, though, it is the continents.

Answer 2

Because of the movement of the tectonic plates.

Answer 3

The earth's poles are changing because the molten core spins independently of the crust.  Check out the mohorovicic discontinuity.
