WebAt places where convection currents in the mantle are moving upward, new lithosphere forms and the plates move apart (diverge). Where two plates are converging (and the … Because of the temperature difference between the Earth's surface and outer core and the ability of the crystalline rocks at high pressure and temperature to undergo slow, creeping, viscous-like deformation over millions of years, there is a convective material circulation in the mantle. Hot material upwells, while cooler (and heavier) material sinks downward. Downward motion of material occurs at convergent … hearth communityWebPlate tectonics theory: • This suggests that the crust of the Earth is split up into seven large plates and a few smaller ones, all of which are able to slowly move around on the Earth’s surface. They float on the semi-molten mantle rocks, and are moved around by convection currents within the very hot rocks. hearth community place
