2.1b earth's interior and plate tectonics

  1. 1. Earth’s Interior and Plate TectonicsBeginning• The earth began as a molten ball of liquid rocks and made up of randomly mixed materials.• Over time the materials separated.• Dense materials such as nickel and iron sank in the center of the earth and form the core.
  2. 2. Earth’s Interior and Plate TectonicsBeginning• Less dense materials rose to the top and form the earth’s crust
  3. 3. Earth’s Interior and Plate TectonicsBeginning• As it cool it’s crust, mantel and core developed
  4. 4. Layers of the Earth Crust• Made up of Rocks/Minerals Upper Mantle called• 5 - 70 KM thick Lithosphere Mantle• Solid. As rocks and minerals Middle Mantle called • Varied Minerals grew cold, they solidify. Asthenosphere • 2,900 KM thick Lower Mantle called • Mesosphere is liquid Mesosphere • Asthenosphere is pyro-plastic Outer Core • Lithosphere is solid• Made up of Nickel and Iron• 2,220 KM thick• Liquid. Due to the heat of the inner core, Iron and Nickel melts and remain liquid. Inner Core • Made up of Nickel and Iron • 1,228 KM thick • Solid due to high pressure from the weight of the upper layers. The hottest layer.
  5. 5. Plate Tectonics• Plate Tectonics – The theory that earth’s surface is made up of large moving plates
  6. 6. Plate Tectonics• Lithosphere – the thin outer shell of Earth, consisting of the crust and the rigid upper mantle.
  7. 7. Plate Tectonics• Athenosphere – The zone of the mantle beneath the lithosphere – consists of slowly flowing solid rock.
  8. 8. Plate Tectonics• Magma – molten rock within the earth.• Heats up materials causing it to expand
  9. 9. Plate Tectonics• Expanding region of athenosphere pushes lithosphere upwards.• This causes the lithosphere to crack.
  10. 10. Two kinds of Plate Movements• Divergent Movement • Convergent Movement
