Mantle convection and plate tectonics provide a general framework for understanding tectonophysics. Transport of heat from the interior of the earth drives solid-state convection. Plate tectonics is a direct consequence of this convection. The relative velocity between plates causes crustal deformation at the boundaries between plates.
