A lithosphere is the rigid, outermost shell of a terrestrial-type planet or natural satellite that is ... The Lithosphere-Asthenosphere boundary is defined by a difference in response to stress: the lithosphere remains .... "attached" to the continental plate above, similar to the extent of the "tectosphere" proposed by Jordan in 1988.
The asthenosphere is the highly viscous, mechanically weak and ductilely deforming region of the upper mantle of the Earth. It lies below the lithosphere, at depths between approximately 80 and 200 km (50 and 120 miles) below the surface. The Lithosphere-Asthenosphere boundary is usually referred to as LAB. .... In other projects.
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 ...
