Earth’s Surface

The earth is made up of four main layers

Earth's Layers

The Earth is made up of four main layers: 

  1. Crust – This is the outer layer of the earth and where we live. It is very thin in comparison to the other layers and is between 0-70km thick.
  2. Mantle – This is the layer below the crust. It is made up of molten or semi molten rock. This layer is 3,000 km thick.
  3. Outer core - This layer is liquid and is 2,000 km thick. It is super hot
  4. Inner core – This is the centre of the earth and just like the outer core it is super hot, but solid not liquid.

The crust and the upper part of the mantle is called the lithosphere. It is rather like a jigsaw puzzle and is made up of large pieces called tectonic plates.
