1. Minerals
A mineral is a naturally occurring, inorganic solid that has a crystal structure and a definite chemical composition

2. Rocks are made up of minerals

3. Coarse Grain large crystals
Rocks have grain sizes
Coarse Grain large crystals
Fine Grain
small crystals

4. Igneous rocks form from magma or lava

5. Magma = inside the Earth Lava = outside the Earth

6. Extrusive Rocks
Lava that cooled outside the earth (on the surface, cooled faster)
Fine grain, smaller crystals

7. Intrusive Rocks Magma that cooled inside the earth (cooled slower)
Coarse grain, larger crystals

8. Metamorphic Rocks
Metamorphic rocks form from heat and pressure deep beneath earths surface
Metamorphic rocks can form out of igneous, sedimentary, or other metamorphic rocks

10. Sedimentary Rocks
Sedimentary rocks form from particles deposited by water and wind that have compacted and cemented together

11. Fossils are ONLY found in sedimentary rocks

12. All rocks on Earth were a different type of rock at one point in time
The Rock Cycle
Rocks are always changing through Earths processes. We illustrate how rocks change through the Rock Cycle.
The rock cycle can follow many different pathways.
All rocks on Earth were a different type of rock at one point in time
