WebOne major effect of internal heat sources can be seen by comparing Figs. 3 and 4, which show the structure of three-dimensional convection in a viscous fluid layer driven by basal heating only (Fig. 3, with H = 0), and by a combination of internal and basal heating (Fig. 4, with H = 12). In three dimensions base-heated convection adopts a spoke planform, with … WebA. An increase in temperature An increase in temperature as we go deep down the Earth leads the rocks to exceed their melting point. Most rocks melt between 800°C and 1200°C. This kind of temperature is found in the lithosphere, lower portion of the Earth's crust and in the asthenosphere B.
