WebThe Mid-Atlantic Ridge is located at the juncture of crustal plates that form the floor of the Atlantic Ocean; it is considered a "slow-spreading" ridge by earth scientists. Running along the crest of the ridge is a long valley that … WebA polarity reversal means that the magnetic North flips to where we know the South Pole is. At the mid-ocean ridge spreading axis, these flips in the direction of the Earth’s magnetic field are recorded in the magnetization of the lava. This creates a symmetrical pattern of magnetic stripes of opposite polarity on either side of mid-ocean ridges.
