D)normal and reversed magnetized strips roughly perpendicular to the ridge axis

Question

Quizplus · Accepted Answer

The linear, magnetic patterns associated with mid-ocean ridges are configured as normal and reversed magnetized strips roughly parallel to the ridge, with the youngest rocks at the crest of the ridge and progressively older rocks on either side. This is due to the process of seafloor spreading and the periodic reversal of Earth's magnetic field.
