New simulations of the asthenosphere find that convective cycling and pressure-driven flow can sometimes cause Earth's most fluid layer of mantle to move even faster than the tectonic plates that ride ...
Tectonic plates are underlain by a low-viscosity mantle layer, the asthenosphere. Asthenospheric flow may be induced by the overriding plate or by deeper mantle convection 1. Shear strain due to this ...
