Evidence of reversals in Earthʹs magnetic field is found along areas of seafloor spreading.

Question

Quizplus · Accepted Answer

Reversals in Earth's magnetic field are recorded in the rocks of the ocean floor as they are formed at the mid-ocean ridges. As new seafloor is formed through seafloor spreading, magnetic minerals in the rocks record the orientation of the Earth's magnetic field at the time of their formation, providing evidence of reversals.
