Is the mantle high density

Witryna20 sty 2011 · The structure of the mantle has been difficult to evaluate on account of the complexity of interpreting the lunar seismograms. From MOI considerations alone we know it is largely homogeneous at least in density. The average P-wave velocity is 7.7 km/s and the average S-wave velocity is 4.45 km/s down to about 1200 km. WitrynaThe asthenosphere (from Ancient Greek ἀσθενός (asthenós) 'without strength') is the mechanically weak [1] 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).
