What is the temperature of the stiffer mantle?Temperature of Earth's Layers
It is a solid, rocky shell that extends to a depth of 2890 km. The stiffer mantle upper is one of the layers of the earth'scrust and composed of hot liquid rock.
By crushing minerals between diamonds, a University of Utah study suggests the existence of an unknown layer inside Earth: Each layer has its own unique properties, with different temperatures, pressures, densities, and composition.
Look to the left to find the pressure. Miyagi and fellow mineral physicist Hauke Marquardt, of Germany's University of Bayreuth, identified the likely presence of a superviscous layer in the lower mantle by squeezing the mineral ferropericlase between gem-quality diamond anvils in presses.

Researchers have used liquid metals to turn carbon dioxide back into solid coal, in a world-first breakthrough that could transform our approach to carbon capture and storage. Where cooler material sinks, plates are pulled together.
Gutenberg discontinuity Noun point between the Earth's mantle and the core below. P-waves primary waves usually arrive first, while s-waves arrive soon after.
Sound waves are P-waves—seismic P-waves are just far too low a frequency for people to hear. The geothermal gradient is a measurement of this increase.
Of course, tectonic plates are not really floating, because the asthenosphere is not liquid. Temperatures in the lower mantle are estimated to range from 1600-4000 o C.
What is the range of density within the stiffer mantle? What is the temperature of the lower mantle? It is made up of ductile rock which exhibits plasticity, bends without fracture, and is extremely highly viscous.
