The document discusses the different layers of the Earth, including the crust, mantle, inner core and outer core. It then provides analogies comparing the Earth's structure to an apple. Finally, it outlines the three main types of rocks - igneous, sedimentary, and metamorphic - and provides a brief description of how each type is formed through melting, layering of materials, and changes caused by pressure and heat respectively.

1. Earth's layers Crust Mantle Inner Core Outer Core

2. The crust and outer mantle make up the lithosphere. About how thick is the lithosphere?

3. If Earth were and apple… Peel = crust Fruit = mantle Outer core = core Inner core = seed

4. What is a rock?

5. A rock is any naturally formed solid in the crust made up of one or more kinds of minerals.

6. What are the 3 types of rocks?

7. Igneous rocks Sedimentary rocks Metamorphic rocks 3 types of rocks How are each of these rocks formed?

8. igneous rock Melted rock cools and becomes hard

9. igneous rocks granite pumice

10. sedimentary rock Layers of mud and sand slowly turn into rock

11. sedimentary rocks sandstone limestone

12. metamorphic rock Rock is changed by pressure and heat

13. metamorphic rocks gneiss slate
