Question

Quizplus · Accepted Answer

The asthenosphere is the more plastic part of the mantle. Option A is incorrect because the lithosphere is made of the crust and the uppermost part of the mantle, and it is less dense than the mantle. Option B is incorrect because the mantle is denser than the lithosphere. Option C is incorrect because the asthenosphere is part of the mantle, not an equivalent of it. Option E is incorrect because the mantle is not always more rigid than the crust.
