Mantle convection is the slow creeping motion of Earth's solid silicate mantle
caused by convection currents carrying heat from the interior of the Earth to the
surface. The Earth's surface ...
The crust and the upper mantle are separated by what is called the Mohorovicic
discontinuity. ... The state of the rocky material in the asthenosphere is similar.
Difference: The lithosphere is less dense and more brittle, the asthenosphere is
more dense and less brittle and the lithosphere is made up of hot molten ...
Lithosphere is hard, while asthenosphere is weak. The lithosphere rides over the
asthenosphere, while the asthenosphere carries the lithosphere.
