1. Rocks A solid part of the Earth’s crust.
Rocks are composed from minerals
Mineral composition- What minerals a rock is made from.

2. Three Types of Rock
Igneous
Sedimentary
Metamorphic

3. Igneous Igneous rocks are formed from the cooling of molten rock
Lava is located on the earths crust
Magma is located below the earths surface

4. Igneous
Two types of Igneous rocks
Intrusive
Extrusive

5. Extrusive igneous rock
Magma is forced to the surface of the rock. Becoming lava and then cooling.

6. Extrusive igneous rock
Types of extrusive Rocks
Basalt
Pumice

7. Intrusive igneous rocks
Magma is forced into the crust and then cools.

8. Intrusive igneous rock
Types of extrusive Rocks
Granite
Pegmatite

9. Sedimentary Rock
Rock particles that are weathered, eroded, deposited then compacted or cemented together.

10. Sediment
Small, solid pieces of material that come from rocks or organisms.

11. Weathering/Erosion
The breaking down of rocks into sediment and the movement of that sediment.

12. Compaction
Rock particles compacted together without cementation minerals.

13. Cementation
The process by which dissolved minerals crystallize and glue rock particles together.

14. Types of sedimentary rocks
Sand stone
Coal
Fossils

15. Metamorphic
Rocks that have changed form and mineral composition without melting.

16. Types of metamorphic
- Schist
- Marble
- Slate

17. Identifying Rocks
Color- unreliable
Texture- the look and feel of a rocks surface
Grains - A particle of mineral or other rock that gives a rock its texture.

18. Rock Cycle
The process where rocks are formed and reformed.
