Question

Quizplus · Accepted Answer

The asthenosphere is able to flow over long periods of time due to its semi-molten state, whereas the lithosphere is rigid and unable to flow.

Answer: C
 The thickness of the asthenosphere varies from place to place and can be thicker or thinner depending on the location.

Answer: D
 The asthenosphere is relatively hot due to the heat produced by the mantle, so it is not relatively cool. Additionally, the density of the asthenosphere is lower than that of the core, so it is not similar in density to the core.
