WebMar 1, 2024 · Asthenosphere. The asthenosphere is the denser, weaker layer beneath the lithospheric mantle. It lies between about 100 kilometers (62 miles) and 410 kilometers … 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 31, 2024 · Plate movement is possible because the lithosphere-asthenosphere boundary is a zone of detachment. As the lithospheric plates move across Earth’s surface, driven by forces as yet not fully understood, they interact along their boundaries, diverging, converging, or slipping past each other. WebBy analogy, the viscous drag of the asthenosphere should also delay the response of the lithospheric plates to relief or application of horizontal boundary stresses on a plate edge, as...
