The Four Layers List the four layers of the Earth. Write how thick each layer is beside its name Name of the Layer Thickness Crust 5-25 miles

Mantle 1800 miles Outer Core 1400 miles Inner Core 800 miles

The 3 Compositional Layers (What they are made of) 1. Crust (Continental and Oceanic)the thin and solid outermost layer of the Earth-mostly rock 2. Mantle-the layer of rock between the Earths crust and core (iron and magnesium) 3. Core-the central part of the Earth below the mantle (iron and nickel)

1. Crust 2. Mantle 3. Core The 5 Physical Layers (solid vs liquid, rigid vs soft) 1. Lithosphere-the crust and upper mantle (rigid/stiff) 2. Asthenosphere- soft layer of the mantle (plastic) 3. Mesosphere- solid layer of the mantle

4. Outer Core- liquid, outer layer of the core. Produces the Earths magnetic field 5. Inner Core- solid, inner layer of the core 1. Lithosphere 2. Asthenosphere 3. Mesosphere 4. Outer Core 5. Inner Core The Crust

5. The crust is like the skin of an apple. 6. At 1600 degrees Fahrenheit, rocks begin to melt. 7. The crust of the Earth is broken into many pieces called plates. 8. The plates float on the soft, plastic mantle which is located below the crust. The Lithosphere

9. The crust is composed of two basic rock types granite and basalt. 10.The crust and the upper layer of the mantle together make up a zone of rigid rock called the lithosphere. 11. The layer below the rigid lithosphere is a zone of asphalt-like consistency called the asthenosphere. It is the part of the mantle that flows and moves the plates of the Earth.

Lithosphere Asthenosphere The Mantle 12. The mantle is the layer located under the sima. It is the largest layer of the Earth, 1800 miles thick. 13. The movement of the mantle is the reason that the plates of the Earth move! 14. The temperature at the top of the

mantle is about 1600 degrees Fahrenheit. 15. The temperature at the bottom of the mantle is about 4000 degrees Convection Currents 16.Convection Currents are caused by the very hot material at the deepest part of the mantle rising, then cooling, sinking again and then heating, rising and repeating the

cycle over and over. 17.http://www.youtube.com/watch?v=Kpoko_l3 4ZE The Outer Core 17.The outer core is so hot that the metals in it are all in the liquid state. 18.The outer core is composed of the melted metals nickel and iron. The Inner Core

19. The inner core has temperatures and pressure so great that the metals are squeezed together and are forced to vibrate in place as a solid. 20. The temperatures may reach 9000 degrees Fahrenheit.
