The ultimate proof of this was the discovery of "magnetic stripes"on the seafloor later in the 1960s: the magnetic domains in oceanic rocks recorded reversal of Earth's magnetic field over time.
WebAlternating stripes of magnetically different rock were laid out in rows on either side of the mid-ocean ridge: one stripe with normal polarity and the adjoining stripe with reversed polarity. The overall pattern, defined by these alternating bands of normally and reversely polarized rock, became known as magnetic striping. WebConcept explainers.
