| What are the two ways a rock can undergo metamorphism? | show 🗑
|
||||
| show | Magma moves through the crust and then heats the surrounding rock and changes it. Magma can come into direct contact with the surrounding rock and the effect of the heat on rock gradually decreases as the distance of the rock increases from the magma.

| Where does Contact Metamorphism usually occur? | show 🗑
|
||||
| show | When pressure builds up in rock that is buried deep below other rock formations or when large pieces of the Earth's crust collide, regional metamorphism will happen. Pressure + Temperature makes the rock deformed and chemically changed.
🗑

| Where does Regional Metamorphism happen? | show 🗑
|
||||
| show | Minerals in the rock may not be stable enough in the new temperature and pressure conditions. So the original minerals change into different minerals that are more stable.
🗑
|

| Describe the difference between foliated and nonfoliated metamorphic rock. | show 🗑
|

| What are index minerals? | show 🗑
|

| show | Folds or bends in metamorphic rock are structures that show that a rock has been deformed.
