WebThe literal meaning of the word isostasy is “equal standstill,” but the importance behind it is the principle that Earth’s crust is floating on the mantle, like a raft floating in the water, rather than resting on the mantle like a raft sitting on the ground. The relationship between the crust and the mantle is illustrated in Figure 9.16. WebMar 1, 2024 · Asthenosphere. The asthenosphere is the denser, weaker layer beneath the lithospheric mantle.

WebJan 6, 2024 · The rock of the asthenosphere is viscous rather than rigid and deforms slowly under stress, like putty. Therefore the lithosphere can move across or through the asthenosphere under the forces of plate tectonics.
