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.

    Near where the charter’d Thames does flow,
    And mark in every face I meet
    Marks of weakness, marks of woe.”
