Inside the earth Inside the earth Presentation Transcript

  • Inside the Earth
  • Composition (What it is made of)
    • Crust
    • Mantle
    • Core
  • The Crust
    • Outer layer
    • 5-100 km thick
    • 2 types of crust
      • Oceanic (very dense, made of basalt)
      • Continental (less dense, made of granite)
  • Oceanic and Continental Crust
  • The Mantle
    • Middle layer
    • Very thick layer
  • The Core
    • Made mostly of iron
    • 1/3 of the earth’s mass
    • Very hot
  • Earth’s Layers
    • How are the earth’s layers similar to an egg?
    • Shell=crust
    • Egg white=mantle
    • Yolk=core
  • 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
  • Tectonic Plates
    • Earth’s crust is broken into about 19 pieces
    • These plates move on top of the asthenosphere
