how thick is the earth crust mantle and core
The interior of Earth, similar to the other terrestrial planets, is chemically divided into layers. The mantle is a layer between the crust and the outer core. Earth's mantle is a silicate rocky shell with an average thickness of 2,886 kilometres (1,793 mi).The mantle makes up about 84% of Earth's volume.It is predominantly solid but in geological time it behaves as a very viscous fluid.he mantle lies between the core below and the crust above. The terrestrial planets (Earth, Venus, Mars and Mercury), Earth's Moon, two of Jupiter 's moons (Io and Europa) and the asteroid Vesta each have a mantle made of silicate rock.
