How dense is the lithosphere
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 … Web22 de jul. de 2024 · Tectonic activity can shape the lithosphere itself: Both oceanic and continental lithospheres are thinnest at rift valleys and ocean ridges where tectonic plates are shifting apart from one another. ... Because both continental and oceanic crust are less dense than the mantle below both types of crust “float” on the mantle.
