  1. Layers of the Earth

  2. Warm Up Imagine yourself taking a journey to the Center of the Earth. What would you experience along the way? Describe your journey in words or a diagram with labels.

  3. Foldable Activity: pg 96-99 • Label the layers on front diagram • Fact-finding mission for • Chemical Layers: classified by what each layer is made of (its composition) • Physical Layers: classified by how each layer is structured or put together

  4. Chemical Layers • Crust • Thinnest layer • Contains oxygen, silicon, aluminum • Oceanic crust is thinner and denser than continental crust • Mantle • 67% of Earth’s mass • More magnesium than crust  denser • Core • Mostly iron (Fe) and nickel (Ni)

  5. Remember… CruManCo Chemical Company

  6. Physical Layers • Lithosphere • Crust + upper, rigid part of mantle • Broken into chunks called tectonic plates • Asthenosphere • Section of mantle underneath lithosphere • Tectonic plates move atop the astheno-

  7. Physical Layers, cont. • Mesosphere • The rest of the mantle; molten rock • Outer Core • Liquid metal • Surrounds inner core • Inner Core • Densest layer • Solid metal
