2.1c layers of the earth

  1. 1. Layers of the Earth 2.1c
  2. 2. 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.
  3. 3. GreenBlueDark Brown Light Brown Red Dark Orange Light Orange Yellow
  4. 4. Lowest Fold Inner CoreInner Core • Inner Core isComposition solid due to great pressure from the weightThickness of the upper layer. • It is extremelyState of Matter hot at more than 6,000° C or 10,800 ° F Color it Yellow
  5. 5. 2nd Fold Outer CoreOuter Core • Outer Core isComposition liquid due to great heat. • Pressure is notThickness great enough to compress it solid.State of Matter • It is extremely hot at more than 1,250° C or 2,280 ° F Color it Orange
  6. 6. 3rd Fold Upper Mantle Lithosphere Convection CurrentsMantle AsthenosphereComposition Middle Mantle Lower Mantle MesosphereThickness • Lower Mantle is liquidState of Matter • Middle Mantle is pyro-plastic and boiling like Lower – liquid spaghetti sauce. Middle – pyro plastic • Upper Mantle is cooled off by the atmosphere Upper - Solid outside and is solid. Color Lower Mantle Red-Orange Color Middle Mantle Red Color Upper Mantle Light Brown
  7. 7. Top Fold ContinentCrust OceanComposition Continental Crust Oceanic CrustThickness • Continental crust is thick because it consists ofState of Matter mountains and plains. • Oceanic crusts are thinner because they are under the heavy pressure of the ocean that compresses it. Color it as follows: 1. Continental Crust - Light Brown, 2, Oceanic Crust – Dark Brown, 3. Continent – Green and 4. Ocean - Blue
