Asthenosphere, zone of Earth’s mantle lying beneath the lithosphere and believed to be much hotter and more fluid than the lithosphere. Asthenosphere derives from Greek asthenes, meaning “weak” or “feeble,” and a relative of the … 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. ]), usually referred to as the Moho, is the boundary between the Earth's crust and the mantle. Only beneath mid-ocean ridges does it define the lithosphere–asthenosphere … The Lithosphere-Asthenosphere boundary is defined by a difference in response to stress: the lithosphere remains rigid for very long periods of geologic time in which it deforms elastically and through brittle failure, while the Asthenosphere deforms viscously and accommodates strain through plastic deformation. Proper usage and audio pronunciation of the word asthenosphere. Asthenosphere definition is - a zone of a celestial body (such as the earth) which lies beneath the lithosphere and within which the material is believed to yield readily to persistent stresses. It was first named in 1914 by the British geologist Joseph Barrell, who divided Earth's overall structure into three major sections: the lithosphere, or outer layer of rock-like material; the asthenosphere… It’s the rigid lithosphere that we live in which rides on the asthenosphere. The Moho lies almost entirely within the lithosphere. A third type of basin exists along convergent plate boundaries – places where one tectonic plate moves under another into the asthenosphere. Definition of asthenosphere in the AudioEnglish.org Dictionary. At the same time, the mantle lithosphere becomes thinned, causing a rise of the top of the asthenosphere. Meaning of asthenosphere. The asthenosphere extends from about 100 km (60 miles) to about 700 km (450 miles) below Earth’s surface. This plasticky layer 80 to 200 km beneath our feet provides the necessary lubrication for plate tectonics. ‘Scientists believe that below the lithosphere is a relatively narrow, mobile zone in the mantle called the asthenosphere.’ ‘Because the radioactive source of heat is deep within the mantle, the fluid asthenosphere circulates as convection currents underneath the solid lithosphere.’ Heat from deep within Earth is thought to keep the See more.
