The asthenosphere is the highly viscous, mechanically weak and ductilely
deforming region of the upper mantle of the Earth. It lies below the lithosphere, ...
May 21, 2008 ... Crust, the upper layer of the Earth, is not always the same. Crust under the
oceans is only about 5 km thick while continental crust can be up to ...
The definition of the lithosphere is based on how Earth materials behave, so it
includes the crust and the uppermost mantle, which are both brittle. Since it is
A zone of the earth's mantle that lies beneath the lithosphere and consists of
several hundred kilometers of deformable rock.
The difference between asthenosphere and lithosphere is how the materials in
these layers can flow. Rocks in the lithosphere are "rigid", meaning that they can
The asthenosphere is the layer of the Earth that lies below the lithosphere. It is a
layer of solid rock that has so much pressure and heat the rocks are can flow ...
