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:
“Professor Fate: My apologies. There’s a polar bear in our car.”
—Arthur Ross. Professor Fate (Jack Lemmon)
“Over hill, over dale,
Thorough bush, thorough brier,
Over park, over pale,
Thorough flood, thorough fire:
I do wander everywhere,
Swifter than the moones sphere;
And I serve the fairy queen,
To dew her orbs upon the green.
The cowslips tall her pensioners be;
In their gold coats spots you see;
Those be rubies, fairy favours,
In those freckles live their savours.”
—William Shakespeare (1564–1616)
