Beneath the central and southern Sierra Nevada, seismic signals confirmed a slow-motion detachment of deep crust, matching theories of global-scale continental evolution over geologic time.

Continental and oceanic plates all fit together to form the outer crust of the planet. Eight major plates are named on the diagram below. Heat from the core makes magma in the mantle rise towards ...
