Evidence from Seismic waves

1. Reflection
2. Refraction

Internal Structure of the Earth

1. Crust
   1. Oceanic crust
   2. Continental crust
   3. Mohorovicic' Discontinuity = Moho
2. Mantle
   1. Lithosphere
   2. Asthenosphere
   3. Mesosphere
   4. Gutenberg Discontinuity
3. Core
   1. Seismic Wave Behaviors
      1. P-wave refraction = Shadow zone.
      2. S-wave refraction = Shadow zone.
   2. Subdivisions of the core
      1. Outer Core
      2. Inner Core
   3. Evidence for core
      1. Seismic waves
      2. Meteorites
