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 … WebThe asthenosphere is ductile due to great pressure and temperatures. The outer core is liquid iron that circulates and moves the lithospheric plates above. Deep mantle convection moves the asthenosphere and the lithosphere above it. The asthenosphere is composed of melted rock that moves easily.
