How hot is the asthenosphere
Did you know?
WebThe asthenosphere is the layer below the lithosphere. Astheno- means lacking strength, and the most distinctive property of the asthenosphere is movement. Because it is mechanically weak, this layer moves and flows due to convection currents created by heat coming from the earth’s core cause [ 33 ].
The 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. [3] Meer weergeven 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 … Meer weergeven 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).
