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:

    “Professor Fate: My apologies. There’s a polar bear in our car.”
    —Arthur Ross. Professor Fate (Jack Lemmon)

    “See how the sacred old flamingoes come,
    Painting with shadow all the marble steps:
    Aged and wise, they seek their wonted perches
    Within the temple, devious walking, made
    To wander by their melancholy minds.”
    —William Butler Yeats (1865–1939)
