Earth's crust lithosphere and asthenosphere
WebThe uppermost solid part of the mantle and the entire crust constitute the Lithosphere. The asthenosphere (in between 80-200km) is a highly viscous, mechanically weak and ductile, deforming region of the upper … WebThe lithosphere is broken into tectonic plates whose motion allows heat to escape from the interior of the Earth into space. The crust lies on top of the mantle, a configuration that …

Did you know?
WebAsthenosphere and Lithosphere constitute the outmost concentric layers of our earth. As we know, earth has many layers. They are mainly divided into four layers. The centre one being the inner core, then we have the outer core. Further, there is the mantle above it and finally the crust. WebEarth's lithosphere, which constitutes the hard and rigid outer vertical layer of the Earth, includes the crust and the uppermost mantle. The lithosphere is underlain by the asthenosphere which is the weaker, hotter, and deeper part of the upper mantle. The lithosphere–asthenosphere boundary is defined by a difference in response to stress.
