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

The Layer of the Earth song and ppt

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