The Earth’s lithosphere is the rigid outer layer, which contains many useful chemical compounds.

Crust and mantle

The Earth’s lithosphere is the rigid outer layer that is made up of the crust and the part of the mantle just below it.

The outer-most layer is called the crust. The crust surrounds the mantle, which surrounds the core. There are 2 parts to the core - the outer core and the inner core, which is the inner most part of the Earth's structure.

The Earth is almost a sphere. These are its main layers, starting with the outermost:

  1. crust - relatively thin and rocky
  2. mantle - has the properties of a solid, but can flow very slowly
  3. outer core - made from liquid nickel and iron
  4. inner core - made from solid nickel and iron

The lithosphere is made up of a mixture of minerals.
