Quizplus · Accepted Answer

The transition zone from the upper mantle to the crust is known as the Mohorovičić discontinuity, or simply the Moho, named after the Croatian seismologist who discovered it. The Asthensosphere is a layer of the mantle beneath the lithosphere that is partially molten and behaves plastically. The Lithosphere is the rigid outer layer of the Earth that includes the crust and upper part of the mantle. The Gutenberg discontinuity is the boundary between the mantle and the outer core.
