Question

How did the discovery of magnetic reversals helped to develop the theory of plate
tectonics?

Answer 1

Geomagnetic reversals helped to prove the theory of plate tectonics by proving the notion of seafloor spreading. Seafloor spreading occurs on the ocean floor at areas called mid-ocean ridges where magma rises from a fault in the floor and forms new crust as the two plates move apart.
