Nettet26. nov. 2024 · Earth’s outer layers. The lithosphere is Earth's cold, rigid outer layer, and consists of both crust and uppermost mantle. It sits on the asthenosphere, which is hot and tends to flow instead of break. The thickness of the lithosphere varies, and geophysicists can calculate these changes by measuring parameters that vary with temperature.
