The earth's crust consists of a number of sections or plates that float on the molten rock of the mantle. These plates move on convection currents caused by heat rising from the center of the earth. The hot magma rises and spreads out on the surface, creating new crust.
o Asthenosphere has convective motion. o This motion pushes lithosphere plates around. Plate tectonics is the movement of large portions of the crust. The movement is caused by magma squeezing out along the mid-oceanic ridges pushing the plates apart in a process called seafloor spreading.
