- The asthenosphere is a part of the upper mantle just below the lithosphere that is involved in plate tectonic movement and isostatic adjustments.n the old oceanic mantle the transition from the lithosphere to the asthenosphere, the so-called lithosphere-asthenosphere boundary (LAB) is shallow (about 60 km in some regions) with a sharp and large velocity drop (5-10%).

Asthenosphere: Definition, Temperature & Density What Is the Asthenosphere? The asthenosphere is part of the upper mantle located below the crust of the earth. The asthenosphere boundary is primarily defined by temperature, and it starts when the crust heats up to 1300° C. At this temperature the crust begins to melt and move more as a liquid. The asthenosphere is important in plate tectonics, as convection currents slowly move the tectonic plates that lie above.

asthenosphere A zone of the earth's mantle that lies beneath the lithosphere and consists of several hundred kilometers of deformable rock. Greek asthenēs, weak; see asthenia + sphere.

Asthenosphere The asthenosphere is the layer of the Earth that lies below the lithosphere. It is a layer of solid rock that has so much pressure and heat the rocks can flow like a liquid. The rocks are less dense than the rocks in the lithosphere. This allows the tectonic plates in the lithosphere to move around on the Earth's surface by floating on the rocks that are slowly flowing like a liquid.

Mechanical properties - 'lithosphere' and 'asthenosphere' Mechanical properties - 'lithosphere' and 'asthenosphere'. We may think we know what we mean by the Earth's 'tectonic plates', but there is more to a tectonic plate that just 'crust'. A clue to this may be found in the other name for 'tectonic plate', which is ' lithospheric plate '.he rocks above the asthenosphere, being the uppermost mantle plus the overlying crust (either continental or oceanic) behave mechanically as one, and comprise what geologists call the 'lithosphere'. The lithosphere moves as one over the weaker, plastic asthenosphere.

Asthenosphere Asthenosphere Asthenosphere, Layer beneath the lithosphere. The asthenosphere is the layer of our planet that lies beneath the lithosphere. It was first named by J. Barrell, a British geologist when he divided the interior of the Earth into three parts. The lithosphere is the outer layer of the Earth that contains crustal plates.

asthenosphere Asthenosphere definition, the region below the lithosphere, variously estimated as being from fifty to several hundred miles (eighty-five to several hundred kilometers) thick, in which the rock is less rigid than that above and below but rigid enough to transmit transverse seismic waves.

Asthenosphere Earth cutaway from core to crust, the asthenosphere lying between the upper mantle and the lithospheric mantle (detail not to scale). The asthenosphere (from Greek ἀσθενής asthenḗs 'weak' + sphere) is the highly viscous, mechanically weak and ductilely deforming region of the upper mantle of the Earth.It lies below the lithosphere, at depths between approximately 80 and 200 km (50 and 120 miles) below the surface.The Lithosphere-Asthenosphere boundary is usually referred to as LAB. The asthenosphere is generally solid, although some of its regions could be melted (e.g. below mid-ocean ridge).n the old oceanic mantle the transition from the lithosphere to the asthenosphere, the so-called lithosphere-asthenosphere boundary (LAB) is shallow (about 60 km in some regions) with a sharp and large velocity drop (5-10%).

- The crust and the upper layer of the mantle together make up a zone of rigid, brittle rock called the Lithosphere. Asthenosphere. The layer below the rigid lithosphere is a zone of asphalt-like consistency called the Asthenosphere. The asthenosphere is the part of the mantle that flows and moves the plates of the Earth.antle. The next layer beneath the crust is called the mantle. It extends to a depth of approximately 1,800 miles and is made of a thick solid rocky substance that represents about 85% of the total weight and mass of the Earth.
