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. WebThe mantle’s convective motions break the lithosphere into plates and move them around the surface of the planet. These plates may move away from, move by, or collide with each other.
