WebLithosphere and Asthenosphere The lithosphere (litho:rock; sphere:layer) is the strong, upper 100 km of the Earth. The lithosphere is made of the tectonic plates we talk about in plate tectonics. The asthenosphere (a:without; stheno:strength) is the weak and easily deformed layer of the Earth that acts as a lubricant for the tectonic plates to ... WebThe asthenosphere is the zone of the earth which lies beneath the lithosphere. It is said to be hotter and more fluid than the lithosphere. We can say it extends from around 100 …
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.
