Since it is rigid and brittle, when stresses act on the lithosphere, it breaks. This is what we experience as an earthquake. Although we sometimes refer to Earth's plates as being plates of crust ...

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 … WebThe less-dense continental crust has greater buoyancy, causing it to float much higher in the mantle.
