Earths thick plasticlike layer is the what?
asthenosphere
How far below the earth's surface is the asthenosphere?
The asthenosphere begins at around 100-150 km depth in the Earth. This is below the lithosphere, which consists of the crust and the uppermost mantle (the plates in plate tectonics).The asthenosphere is in the mantle, but it is still unclear how much of the mantle (which goes down to a depth of ~2900 km) is actually part of the asthenosphere.
What is the depth of the mantle?
Earth's mantle is a rocky shell about 2,890 km (1,800 mi) thick that constitutes about 84 percent of Earth's volume. Two main zones are distinguished in the upper mantle: the inner asthenosphere composed of flowing rock in the state of plasticity, about 200 km thick, and the lowermost part of the lithosphere, composed of rigid rock, about 50 to 120 km thick. A thin crust, the upper part of the lithosphere, surrounds the mantle and is about 5 to 75 km thick. The mantle is divided into sections which are based upon results from seismology. These layers (and their depths) are the following: the upper mantle (starting at the Moho, or base of the crust around 7 to 35 km, downward to 410 km), the transition zone (410-660 km), the lower mantle (660-2891 km), and in the bottom of the latter region there is the anomalous D" layer with a variable thickness (on average ~200 km thick)

What is the range of the depth of the asthenosphere?
The asthenosphere is the lower portion of the Earth's mantle. Its temperature ranges from 1000 degrees Celsius to 2500 degrees Celsius.
How thick is the asthenosphere crust?
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.
