Polar Wander

Polar wander is the movement of the North and South Poles of the Earth with respect to the continents. This motion can be divided into two components: apparent polar wander, due to continental drift (the continents' movement over the mantle), and true polar wander, in which the mantle and the crust rotate together into new orientations.
