Web26 de nov. de 2024 · 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. WebFurther, we see that oceanic lithosphere is not as dense as the asthenosphere, it is less dense. But, after tens of millions of years, it keeps becoming increasingly denser than the asthenosphere. It happens so as the chemically differentiated oceanic crust is lighter than asthenosphere, however, thermal contraction of the mantle lithosphere makes it denser …
