Earth’s Layers Aim= Which layer of Earth is the thinnest?
Earth’s Layers Crust – Thin outer layer Mantle – Hot / viscous rock Liquid outer core – Metallic Solid inner core – Iron and Nickel
Layers of the Earth Skin of the peach is the crust Meat of the peach is the mantle Pit of the peach is the core
1) Crust The lithosphere 2 types Continental: Thicker, less dense, felsic (granite) Oceanic: Thinner, more dense, Mafic, (Basaltic) Beneath the crust is the MOHO (boundary between crust and mantle)
2) Mantle Asthenosphere: Stiffer Mantle Upper Mantle, Plastic, soft malleable Stiffer Mantle Solid, thick
3) Outer Core Liquid Iron and Nickel Composition
4) Inner Core Solid Iron and Nickel Composition
5) Relationships AS Depth Increases, Pressure Increases As Depth Increases, Temperature Increases ESRT Page 10
What is the pressure at 5000km? At what depth is the temperature 3000 C?
