The interior of the earth is composed of three layers.
1. Crust which is divided into upper and lower by the Conard Discontinuity.
2. Mantle which is divided into upper and lower by the Reptite Discontinuity.
3. Core which is divided into upper and lower by the Transition or Lehman Discontinuity.
4. Crust and mantle is separated by the Moho discontinuit.
5. Mantle and core is separated by the Gutenberg discontinuity.
