Question

The lithospheric plates float on top of the _______, which is a weak part of the mantle that flows slowly.

Answer 1

asthenosphere

Step-by-step explanation:

The lithospheric plates (also called tectonic plates) float on top of the asthenosphere. The temperature and pressure conditions in the asthenosphere make it weaker than the lithosphere and, although solid, able to flow very slowly. This slow, gradual flow of mantle rock in the asthenosphere is one of several possible processes that cause the lithospheric plates to move.

Answer 2

The lithospheric plates float on top of the _______, which is a weak part of the mantle that flows slowly.
