1. Rock Cycle

2. 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. 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. 2) Write down the definition for a mineral. 3) What is the difference between a rock and a mineral? 3) What is the difference between a rock and a mineral?

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

4. Intermediate States: Lava & Magama Lava is expelled from earth. Magma is still below earth.

5. Intermediate States: Sediment Broken rock fragments from the process of Weathering.

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

7. Processes 3. Weathering, Eroding, Depositing, Compaction, Cementation (WEDCC) 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

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

9. Questions to ponder… What does the rock cycle that you created tell us about the fate of rocks? 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? How are rocks classified? How does this different from the classification of minerals? Can you figure out which station held which of the three types of rock? Can you figure out which station held which of the three types of rock?
