.
1) crust describes the outermost shell of the Terrestrial planet Earth's crust is generally divided into older thicker Continental Crust and younger denser Oceanic crust earth has three layer The crust the Mantle and the core The crust is made of solid Rocks and Minerals.
.
2) is also known as mineral skin because it is the layer of the uppermost crust of the earth composed of Rocks and Minerals.
.
3) the interior structure of the Earth is layered in spherical shell's an outer silicate solid crust are highly viscous atmosphere and mantle a liquid outer core that is much less viscous than the Mantle and the solid inner core.
