Definition of Asthenosphere. Meaning of Asthenosphere. Synonyms of Asthenosphere

- The asthenosphere (from Ancient Gr**** ἀσθενός (asthenós) 'without strength') is the mechanically weak and ductile region of the upper mantle of Earth...
- The lithosphere–asthenosphere boundary (referred to as the LAB by geophysicists) represents a mechanical difference between layers in Earth's inner structure...
- by the asthenosphere which is the weaker, hotter, and deeper part of the upper mantle that is able to convect. The lithosphere–asthenosphere boundary...
- the asthenosphere is hotter and flows more easily. In terms of heat transfer, the lithosphere loses heat by conduction, whereas the asthenosphere also...
- down. This releases water into the hotter asthenosphere, which leads to partial melting of the asthenosphere and volcanism. Both dehydration and partial...
- as the result of the rigid lithosphere sliding down the hot, raised asthenosphere below mid-ocean ridges. Although it is called ridge push, the term is...
- lithosphere and the asthenosphere under the Juan de Fuca Plate. The study extends the theory of partial melt in the lithosphere-asthenosphere boundary to subduction...
- viscous asthenosphere. The oceanic lithosphere is formed at an oceanic ridge, while the lithosphere is subducted back into the asthenosphere at ocean...
- ****ociated in almost all cases with partial melting of the overlying asthenosphere due to the addition of volatiles (especially water) expelled from the...
- in ice thickness related to glaciation. The lithosphere rests on the asthenosphere, a viscous layer that in geological time scales behaves like a fluid...
