This geological process saw increased activity during the mid-Cretaceous in its namesake "pulse." The Vine-Matthews-Morley hypothesis predicted that, because of reversals in the Earth's magnetic field, this process should result in alternating bands of magnetically polarized rock.

This geological process saw increased activity during the mid-Cretaceous in its namesake "pulse." The Vine-Matthews-Morley hypothesis predicted that, because of reversals in the Earth's magnetic field, this process should result in alternating bands of magnetically polarized rock. Caused by asthenospheric convection currents, this process occurs at triple junctions where basaltic magma emerges from a divergent boundary between two oceanic plates. For 10 points, name this process contributing to continental drift, in which new oceanic crust is formed at mid-ocean ridges.
