Hot material upwells, while cooler (and heavier) material sinks downward. Downward motion of material occurs at convergent …

WitrynaThe mantle extends from Moho’s discontinuity to a depth of 2,900 km. The asthenosphere is the upper portion of Mantle. It is the chief source of magma that finds its way to the surface during volcanic eruptions. The crust and the uppermost part of the mantle are called the lithosphere. WitrynaThe layer below the rigid lithosphere is a zone of asphalt-like consistancy called the Asthenosphere. The asthenosphere is the part of the mantle that flows and moves the plates of the Earth.
