1. Aim: How are metamorphic rocks formed and classified?
Do Now: Why are sedimentary rocks the only type to have fossils?

2. How is the following creature changing?

3. How does an igneous rock get metamorphosed?
Granite
Gneiss

4. How do we define metamorphism?
Heat
Pressure
Metamorphism – changes within the original (parent) rock that forms into a new rock by heat and/or pressure.

5. Riddle of the day: Why are metamorphic rocks called the music rocks?
Because they have “BANDS”!! 

6. How can we describe some characteristics due to metamorphism?
Metamorphism causes:
• Foliation – alignment of minerals.
• Banding – folding of minerals in the rock
• Recrystalization – crystals will grow larger
• Increase in density

16. How can we describe regional metamorphism?
Why is Mount Everest so tall?
1. Regional metamorphism: occurs during mountain building or plate movement
Parent rock becomes distorted (folded) and transforms into a metamorphic rock
Rocks below are subjected to intense heat and pressure due to the overlying rocks and sediments
What do you think is happening to the rocks underneath the mountain? Why?

17. How can we illustrate the process of Regional Metamorphism?
Through the process of metamorphism (Low to High grade) a sedimentary rock, Shale, becomes a metamorphic rock.

18. How do we interpret the metamorphic table?

19. How can we describe contact metamorphism?
2. Contact metamorphism: lava/magma touches the surrounding rock & changes it into a metamorphic rock. • HEAT only (no pressure). • Foliation does not take place
Crystals grow and get bigger

20. How do we interpret the metamorphic table?
Granite
conglomerate
