WebThe mantle extends from Moho’s discontinuity to a depth of around 2, 900 km. the upper portion of the mantle is known as the aesthenosphere. The mantle is the main source of magma that forms its way to the surface during volcanic eruptions. It has a density higher than that of the crust. WebBehaviorally, the outer earth layers are divided into the lithosphere and asthenosphere (see right side of enlarged drawing ). The lithosphere is the cold, rigid outer layers, and is composed of the crust and the outermost portion of the mantle. The underlying asthenosphere is all ultramafic mantle, but it is hot and plastic.
