Quizplus · Accepted Answer

Marine magnetic anomalies are formed as a result of the alteration in Earth's magnetic field, which is aligned along the magnetic north. Mid-ocean ridges are divergent plate boundaries, where new oceanic crust is formed by the upwelling of magma from the mantle. As the newly-formed crust cools and solidifies, it retains a record of Earth's magnetic field at that time. These magnetic anomalies laid roughly parallel to mid-ocean ridges, forming a symmetrical pattern of stripes on either side of the ridge.
