  1. Inside the Earth

  2. Composition (What it is made of) • Crust • Mantle • Core

  3. Outer layer 5-100 km thick 2 types of crust Oceanic (very dense, made of basalt) Continental (less dense, made of granite) The Crust

  4. Oceanic and Continental Crust

  5. Middle layer Very thick layer The Mantle

  6. The Core • Made mostly of iron • 1/3 of the earth’s mass • Very hot

  7. How are the earth’s layers similar to an egg? Shell=crust Egg white=mantle Yolk=core Earth’s Layers

  8. Physical Structure of the Earth(5 Layers) • Lithosphere - rigid outer layer (crust) • Asthenosphere - solid rock that flows slowly (like hot asphalt) • Mesosphere - middle layer • Outer Core - liquid layer • Inner Core - solid, very dense

  9. Tectonic Plates • Earth’s crust is broken into about 19 pieces • These plates move on top of the asthenosphere

  10. The End
