In the … 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.
How does the asthenosphere respond to stress
Did you know?
The asthenosphere is a part of the upper mantle just below the lithosphere that is involved in plate tectonic movement and isostatic adjustments. It is composed of peridotite, a rock containing mostly the minerals olivine and pyroxene. The lithosphere-asthenosphere boundary is conventionally taken at the 1,300 °C (2,370 °F) isotherm. Below this temperature (closer to the surface) the mantle …

Therefore the lithosphere can move across or through the asthenosphere under the forces of plate tectonics. This also means that earthquake faults are cracks that extend through the lithosphere, but not beyond it. Lithosphere Structure
