The lithosphere is underlain by the asthenosphere which is the weaker, hotter, and deeper part of the upper mantle. The lithosphere–asthenosphere boundary is defined by a difference in response to stress.
WebJul 15, 2024 · “Crust ” describes the outermost shell of a terrestrial planet. Our planet ’s thin, 40-kilometer (25-mile) deep crust—just 1% of Earth ’s mass—contains all known life in the universe. Earth has three layers: the crust, the mantle, and the core.The crust is made of solid rocks and minerals.Beneath the crust is the mantle, which is also mostly solid …
