Compaction |
The weight from the layers of sediment forces out fluids and decreases the space between grains. |

|
Cementation |
When minerals dissolved in water crystallize between sediment grains |

Biochemical Rock |
Is a sedimentary rock that was formed by orgaisms or contains the remains of organisms. |
|
|
Metamorphism |
Is any process that affects the structure or composition of a rock in a solid state as a result of changes in tempature, pressure, or the addition of chemical fluids. |

|
Plastic Deformaton |
Permanet change in shape by bending and folding. |

|
Foliated Rocks |
Contain parallel layers of flat and elongated minerals. |
|
|
Nonfoliated Rocks |
Metamorphic rocks that have mineralgrains with a random, interlocking texture. |
|
|
Contact Metamorphism |
Magma comes in contact with existing rock, and its thermal energy and gases interact with the surrounding rock, forming new metamorphic rock. |
|
|
Regional Metamorphism |
