The sea level highstand during the mid-Cretaceous period can be attributed to this process's namesake pulse.
The sea level highstand during the mid-Cretaceous period can be attributed to this process's namesake pulse. The Vine-Matthews-Morley hypothesis states that this process causes evidence for Earth's reversing magnetic field through the appearance of alternating stripes in polarized rock. Robert Dietz's model of this process assumed that a sliding surface was present at the base of the lithosphere. This process was first described by Harry Hess, and it is caused by the asthenosphere's convection currents, which propel basaltic magma to the Earth's surface. For 10 points, name this process responsible for continental drift that creates new oceanic crust at mid-ocean ridges.
