The lithosphere is rigid and brittle, whereas the asthenosphere is ductile and capable of slow plastic flow. The lithosphere is entirely liquid metal, whereas the asthenosphere consists of solid mantle silicates. The lithosphere undergoes high-grade metamorphism, whereas the asthenosphere has no pressure or temperature gradients. The lithosphere lacks tectonic plates, whereas the asthenosphere is divided into rigid moving tectonic plates.
