magnetic reversal
Periodically, the magnetic field of the earth reverses polarity. The direction of the magnetic field is recorded in the magnetic properties of rocks when they are erupted. Rocks are being continuously added at sea floor spreading regions, and thus the magnetic reversals are recorded as pairs of parallel 'stripes' alongside the mid ocean spreading ridge.
