They are highly molten, weak, capable of flowing.
the inner core
The asthenosphere, moves with convection
A portion of the upper mantle known as the asthenosphere.
Crustal (or lithospheric) plates are pulled or pushed by the movement of heated rock in the asthenosphere.
solid
No. The rock of the asthenosphere forms a ductile solid.
The rock in the asthenosphere behaves differently from the rock above because the rate of deformation is different.
The Asthenosphere.
The rock in the asthenosphere is under immense pressure from the overlying rock. Increased pressure raises the melting point of most substances.
the inner core
asthenosphere
The asthenosphere contains ultramafic rock that is ductile due to the extreme heat and pressure it experiences.

yes it is brittle but shifting
