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.

Famous quotes containing the words polar and/or wander:

    “There are people who read too much: bibliobibuli. I know some who are constantly drunk on books, as other men are drunk on whiskey or religion. They wander through this most diverting and stimulating of worlds in a haze, seeing nothing and hearing nothing.”
