WebThese plates lie on top of a partially molten layer of rock called the asthenosphere. Due to the convection of the asthenosphere and lithosphere, the plates move relative to each other at different rates, from two to 15 centimetres (one to six inches) per year. ...

Web29 May 2024 · Temperature of the lithosphere can range from a crustal temperature of zero degrees Celsius (32 degrees Fahrenheit) to an upper mantle temperature of 500 degrees … Web11 Nov 2015 · Temperature, lithosphere-asthenosphere boundary, and heat flux beneath the Antarctic Plate inferred from seismic velocities Meijian An, Corresponding Author Meijian … other words for irThe lithosphere-asthenosphere boundary is conventionally taken at the 1,300 °C (2,370 °F) isotherm. Below this temperature (closer to the surface) the mantle behaves rigidly; above this temperature (deeper below the surface) it acts in a ductile fashion. See more The asthenosphere (from Ancient Greek ἀσθενός (asthenós) 'without strength') is the mechanically weak and ductile region of the upper mantle of Earth. It lies below the lithosphere, at a depth between ~80 and 200 km (50 and 120 … See more The asthenosphere extends from an upper boundary at approximately 80 to 200 km (50 to 120 miles) below the surface to a lower boundary at a depth of approximately 700 … See more Decompression melting of asthenospheric rock creeping towards the surface is the most important source of magma on Earth. Most of this erupts at See more • Seismology § History See more The asthenosphere is a part of the upper mantle just below the lithosphere that is involved in plate tectonic movement and isostatic adjustments. It is composed of peridotite, a rock containing mostly the minerals olivine and pyroxene. The lithosphere … See more The mechanical properties of the asthenosphere are widely attributed to the partial melting of the rock. It is likely that a small amount of melt is present through much of the asthenosphere, where it is stabilized by the traces of volatiles (water and carbon dioxide) … See more • Hirschmann, Marc M.
