Roughly 40 miles, but up to 140 miles.
The asthenosphere (or low-velocity zone) is believed to be about 200 kilometers (120 miles) thick. The layers of rock that make up the asthenosphere are thought to be partially melted and hotter than those in the lithosphere. If this were true, it would explain why the asthenosphere might also have less surface integrity, making it a possible source for the generation of new magma.
The asthenosphere is approximately 250 km to 400 km thick beneath the Earth's crust. However, its exact thickness can vary in different regions and can reach up to 700 km in some areas.
The material that would be the most appropriate to represent the asthenosphere is Oobleck, corn starch and water mixed together, because it is not liquid nor solid. The asthenosphere is nor liquid or solid. It is something in between but none exactly.
We live on the crust. It is the thinnest layer of rock.
The asthenosphere, located in the upper part of the mantle, can flow like a thick liquid due to high temperatures and pressures that allow for the movement of rock over long periods of time.
180 km
The asthenosphere is variously estimated as being from fifty to several hundred miles (eighty-five to several hundred kilometers) thick and consists of deformable rock.It is a zone of the Earth's mantle that lies beneath the lithosphere.For more information see the answer to the Related Questionshown below.
The asthenosphere is typically around 100-200 kilometers thick beneath the Earth's crust. It is a semi-fluid layer of the upper mantle that allows for the movement of tectonic plates.
The asthenosphere is a layer in the Earth's mantle that lies between 100 km to 200 km beneath the Earth's surface. It is characterized by its semi-fluid or ductile behavior due to high temperatures and pressures.

The asthenosphere is approximately 100-200 kilometers thick beneath the Earth's crust. It is a semi-plastic layer of the mantle that lies below the lithosphere and plays a key role in plate tectonics and mantle convection.
Earth's mantle is about 1,800 miles thick.
20000 miles thick
the mantle, which contains the lithosphere, asthenosphere and the mesosphere
The asthenosphere, which is a soft plastic, is between approximately 62 and 124 miles below the surface. It is just below rigid lithosphere.
The asthenosphere is a semi-fluid layer in the upper mantle of the Earth that lies beneath the lithosphere. It exhibits ductile behavior, allowing tectonic plates to move over it. The asthenosphere plays a key role in plate tectonics and the movement of Earth's lithospheric plates.
