1. Rock Cycle

2. In your notes… Take out a BLANK page in your notes What is a rock?
How is it different than a mineral?
Give 4 characteristics of every rock…

3. Do Now
1) Move to each station that is set up with rocks. Spend two minutes at each station and list at least 4 characteristics of the rocks that you see.
2) Write down the definition for a mineral.
3) What is the difference between a rock and a mineral?

4. Rock Definitions Igneous Rock: Sedimentary Rock: Metamorphic Rock:
Magma and Lava cools and hardens to form
Sedimentary Rock:
The accumulation of various types of sediments compacted together
Metamorphic Rock:
Heat and pressure cause existing rocks to change their minerals and/or shape

5. #1 Intermediate States: Lava & Magma
Magma is still below earth.
Lava is expelled from earth.

6. #2 Intermediate State: Sediment
Broken rock fragments from the process of Weathering.

7. Processes (There are 3!) 1. Melting and Cooling (Hardening)
2. Heat/pressure (Below Earth)

8. Processes
3. Weathering, Eroding, Depositing, Compaction, Cementation (WEDCC)
Breaking apart of rocks into sediment fragments, and then transporting them to another location, where they settle.
Compaction: weight of overlying sediments causes pressure pushing sediments together
Cementation: minerals dissolved in water are transported and left behind to cement sediments together

9. Do Now!
Count off by 8 and get into groups. Try to arrange the rock cycle with the pieces given.

10. Take out a new blank page and put your name at the top…
Answer these questions…
What does the rock cycle that you created tell us about the fate of rocks?
How are rocks classified? How does this different from the classification of minerals?
