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.

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
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
