asthenosphere (from
Ancient Gr**** ἀσθενός (asthenós) 'without strength') is the
mechanically weak and

upper mantle of Earth...
- The lithosphere–
asthenosphere boundary (referred to as the LAB by geophysicists)
represents a

- the
asthenosphere is
hotter and
flows more easily. In
terms of heat transfer, the
lithosphere loses heat by conduction,
whereas the
asthenosphere also...

Earth is
divided into an upper,
lithosphere layer and a lower,
asthenosphere layer. The
lithosphere layer is
composed of two parts, an upper, the...

asthenosphere which is the weaker, hotter, and
deeper part of the
upper mantle that is able to convect. The lithosphere–

hotter asthenosphere,
which leads to
partial melting of the
asthenosphere and volcanism. Both
