WebMantle 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 … WebAug 22, 2014 · Convection currents in the asthenosphere helps form subduction zones at convergent boundaries and ridges at divergent boundaries. This slow and continuous convection causes the plates on...
