      I was always taught that there were 5 layers to the Earth

      Starting from the inside and working out…

      1) Inner core
      2) Outer core
      3) Mantle
      4) Upper mantle
      5) Crust

      but I guess it depends on what you are counting as a layer. On the crust itself there are lots of different layers of rock – do they count as layers too?
