One area which does not show evidence of this process is the Jurassic Quiet Zone, and time periods during which this process did not occur are dubbed "superchrons.
Glatzmaier and Roberts used a supercomputer to simulate this process. Vincenzo Carbone discovered that this process's occurrence follows a Levy distribution, which would quash Richard Muller's theory that this process does not occur spontaneously, but must be catalyzed by an outside event. One area which does not show evidence of this process is the Jurassic Quiet Zone, and time periods during which this process did not occur are dubbed "superchrons." Morley, Vine, and Matthews first theorized a test for the veracity of the sea floor spreading theory that depended on this phenomenon, which they theorized would leave polarity markings on bands of rocks parallel to the mid-Atlantic ridge. For 10 points, name this process by which certain field reorients its north and south poles.
