What is the process of metamorphism?

2. The process by which heat, pressure or chemical processes turn one type of rock into another.

3. Most metamorphic rock forms deep within the Earth’s crust.
All metamorphic rock forms from existing igneous, metamorphic and sedimentary rock

4. Can form two ways
Contact metamorphism- occurs when small volumes of rock come into contact with magma
Regional metamorphism- occurs when large areas of Earth’s crust are affected by the heat and pressure caused by the movement and collisions of tectonic plates.

5. FOLIATED ROCKS
Texture in which the minerals are aligned in planes or bands.
Examples are slate, schist or gneiss
