Lithosphere convection

WebSub-lithospheric small-scale convection (SSC) (Ballmer et al., 2007; Buck, 1985; Haxby & Weissel, 1986) has been proposed to explain these phenomena. This dynamic process, … Mantle convection is the very slow creeping motion of Earth's solid silicate mantle as convection currents carry heat from the interior to the planet's surface. The Earth's surface lithosphere rides atop the asthenosphere and the two form the components of the upper mantle. The lithosphere is divided into a number of tectonic plates that are continuously being created or consumed at plate boundaries. Accretion occurs as mantle is added to the gro…
