The main difference between the lithosphere and the asthenosphere is the:

A) asthenosphere is less rigid
B) asthenosphere flows less easily
C) asthenosphere is cooler
D) asthenosphere has more oceanic crust
E) asthenosphere has more continental crust

Lithosphere

The rigid outer layer of the Earth, consisting of the crust and the upper mantle.

Asthenosphere

The viscous, semi-fluid layer of the Earth's mantle located below the lithosphere, involved in plate tectonic movements and convection currents.

Less Rigid

Describing a structure or material that has a lower level of stiffness and resistance to deformation compared to more rigid counterparts.
