The Lithosphere and Asthenosphere
Can you think of a solid that can flow?
You use one twice a day! Toothpaste is a solid that can flow. Is the asthenosphere made of toothpaste? Only if the toothpaste is ultramafic in composition, and then it would only be able to flow if it were really, really hot. Still the toothpaste analogy gives you a good image of how the asthenosphere might behave if you squeezed it!
The lithosphere is composed of both the crust and the portion of the upper mantle that behaves as a brittle, rigid solid. The lithosphere is the outermost mechanical layer, which behaves as a brittle, rigid solid. The lithosphere is about 100 kilometers thick. How are crust and lithosphere different from each other?
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 rigid and brittle, when stresses act on the lithosphere, it breaks. This is what we experience as an earthquake.
Although we sometimes refer to Earth’s plates as being plates of crust, the plates are actually made of lithosphere.
The asthenosphere is solid upper mantle material that is so hot that it behaves plastically and can flow. The lithosphere rides on the asthenosphere.
- The lithosphere is the brittle crust and uppermost mantle.
- The asthenosphere is a solid but it can flow, like toothpaste.
- The lithosphere rests on the asthenosphere.

What three asthenosphere characteristics set it apart from the lithosphere?
Lithosphere and asthenosphere comparison
|Characterized as elastic and less ductile||Has a higher degree of ductility than the lithosphere|
|Ranges from a depth of 80km and 200 km below the earths surface||Extends to a depth of 700km below the earths’ surface|

What are the lithosphere’s physical characteristics?
The atmosphere above and the asthenosphere (another part of the upper mantle) below form the boundaries of the lithosphere, which is composed of the crust and the brittle upper part of the mantle, the outermost layers of the Earth’s structure.
What are the asthenosphere’s physical characteristics?
The interaction of temperature and pressure on asthenospheric materials results in a material that can be described as plastic-like, with significantly less rigidity than the lithosphere above it.
How do the asthenosphere’s physical attributes compare to those of the lithosphere, according to the quizlet?
b>The athenosphere is a plastic or malleable region of Earth’s interior, whereas the lithosphere is a liquified rock layer. Both are capable of flow. The athenosphere is plastic or malleable and capable of slow flow.
What distinguishes the lithosphere from the atmosphere?
The lithosphere is the solid portion of the Earth, which includes the rocks and mountains, the hydrosphere is the liquid portion of the Earth, which includes the rivers, lakes, and oceans. The atmosphere is the space above the Earth’s surface, which includes the air that we all breathe.
What distinguishes the lithosphere from the asthenosphere, brainily?
The asthenosphere is the layer below the lithosphere, which is composed of the uppermost weaker layer of the mantel, and the lithosphere is the layer beneath the asthenosphere, which is composed of the Earth’s crust and the uppermost solid layer of the mantel.
What features of the asthenosphere permit the movement of the lithosphere?
Convection currents produced in the asthenosphere push magma upward through volcanic vents and spreading centers to create new crust. Heat from deep within Earth is thought to keep the asthenosphere malleable, lubricating the undersides of Earth’s tectonic plates and allowing them to move.
How are the structures of the lithosphere and asthenosphere different?
The asthenosphere is made up of partially molten upper mantle material that behaves plastically and can flow, while the lithosphere is made up of the crust and the part of the upper mantle that behaves as a brittle, rigid solid.
What distinguishes the asthenosphere’s constituents from the lithosphere’s constituents?
Because the rocks in the asthenosphere are more ductile than those in the lithosphere and can flow like silly putty instead of just bending or breaking, the asthenosphere is made up of tectonic plates, which is the main distinction between the two.
Choose all that apply. How does the lithosphere differ from the asthenosphere?
The lithosphere, which lies over the asthenosphere and is the reason why oceanic ridges are higher than the rest of the sea floor, tends to break, whereas the asthenosphere tends to flow.
What distinguishes the asthenosphere quizlet from the lithosphere plates?
The asthenosphere is where convection currents drive the plates apart and is made up of Upper Mantle Flowing. Oceanic crust is dense and thin, while continental crust is thick but less dense. The lithosphere is the tectonic plate and is made up of crust (continental and oceanic), Moho line, and Upper Mantle Rigid.
