Unlike the lithosphere,the asthenosphere ____________.
A) is relatively weak and flows readily
B) has a density similar to the core
C) varies in thickness from place to place
D) is relatively cool

Question

Quizplus · Accepted Answer

The asthenosphere is relatively weak and flows readily due to its partially molten state and the high temperatures and pressures within it. This property makes it different from the lithosphere, which is more rigid and brittle. Choice B is incorrect as the asthenosphere has a lower density than the core. Choice C is not the defining characteristic of the asthenosphere, although it may have some variability in thickness. Choice D is also incorrect as the asthenosphere is relatively hot due to its proximity to the mantle.
