What Is The Asthenosphere Made Of? (Structure Explain)

Webb22 okt. 2024 · The asthenosphere (finally!) lies above the mesosphere in the upper mantle, stretching from about 62 miles to 410 miles deep. The rock of the asthenosphere – primarily peridotite – is mostly solid, but because it’s under such high pressure it flows like tar in plastic (or ductile) fashion at a rate of perhaps an inch or two per year. Webbasthenosphere [ ăs-thĕn ′ə-sfîr′ ] The upper part of the Earth's mantle, extending from a depth of about 75 km (46.5 mi) to about 200 km (124 mi). The asthenosphere lies … 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 mi) below the surface, and extends as deep as 700 km (430 mi). However, the lower … Visa mer 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 Visa mer 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 kilometers (430 mi). Lithosphere-asthenosphere boundary The lithosphere … Visa mer Decompression melting of asthenospheric rock creeping towards the surface is the most important source of magma on Earth. Most of this erupts at Visa mer • San Diego State University, "The Earth's internal heat energy and interior structure" Archived 3 March 2011 at the Wayback Machine Visa mer 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) … Visa mer • Seismology § History Visa mer • Hirschmann, Marc M.
