2. Metamorphic Rocks
Metamorphic rocks form from heat and pressure deep beneath earths surface

3. Metamorphic Rocks
Metamorphic rocks can form out of igneous, sedimentary, or other metamorphic rocks

4. Metamorphic Rocks Foliated – wavy layers due to high pressure
Nonfoliated – blocky crystal shapes
Non- marble, quartzite. Foliated – gnesis, schist

5. Regional Metamorphism – high temp/pressure affects a large region
