The asthenosphere is a plastic layer of rock located in the upper mantle, below the lithosphere (earth's crust and uppermost mantle). It is responsible for the movement of tectonic plates due to its partially molten and ductile nature.

What are three parts that make up earths mantle?

The three parts that make up the Earths mantle are the crust, core, and mantle.


Is the asthenosphere part of the earths crust?

No, the asthenosphere is not part of the Earth's crust. It is a layer within the upper mantle, located below the lithosphere. The asthenosphere is a semi-fluid region that allows the lithospheric plates to move.


If the tectonic plates float on a layer of the earths crust what is it called?

The mantle or perhaps you are referring to the asthenosphere, the upper layer of the earth's mantle, below the lithosphere, in which there is relatively low resistance to plastic flow and convection is thought to occur.


Is the asthenosphere the thinnest layer?

No. The mantle is below the crust (what we live on), which is the thinnest layer of the earth.


What is the upper part of the earths mantle?

The asthenosphere is the upper part of Earth's mantle. It is partially molten (plastic rheology) and mechanically detached from the lithosphere, which is mostly the Earth's crust (but also a little bit of upper mantle). The density of the upper mantle is your mom! (yo mamma!)


What is the thick layer of earths interior that lies between the crust and the core?

the mantle, which contains the lithosphere, asthenosphere and the mesosphere


What are the three layers of the mantle?

Lithosphere is the layer clostest to the earths crust. It is the layer that contains the sial and sima. Asthenosphere is the next layer clostest to the earths crust. Mesosphere is the inner most layer of the mantle than it goes to the core... Outer core, and inner core


Part of earth's interior that flows like plastic?

Partially molten, plastic like, flowing layer located below the solid part of Earth's mantle is the Asthenosphere. The asthenosphere is mechanically weak and ductiley deforming region of the upper mantle.


The asthenosphere is part of which layer of the earth?

The Asthenosphere is part of the Mantle of the Earth


What is the difference between lithosphere and asthenosphere?

The difference between the lithosphere and the asthenosphere is that the asthenosphere is the lower part of the upper mantle it behaves like a plastic but flows much more easily than the rest of the mantle. The lithosphere however, includes the entire crust and the uppermost part of the mantle, it is more rigid and brittle and doesn't flow.


What is the crust and the upper mantle are called?

The crust and uppermost hard rocky mantle, together, is known as the lithosphere, which is above the plastic-like upper mantle area known as the asthenosphere.


What is the plastic zone below the upper mantle?

The plastic zone below the upper mantle is called the asthenosphere. It is a semi-fluid layer of the upper mantle where rock can flow like a viscous fluid over long periods of time. The asthenosphere plays a crucial role in the movement of tectonic plates.
