| Question | Answer |
|---|---|
| weight from layers of sediment forces out fluids and decreases the space between grains | compaction |
| minerals dissolve in water crystallize between the sediment grain | cementation |
| sedimentary rocks that are made up of broken pieces of minerals and rock fragments | clastic rocks |
| broken pieces and fragments | clasts |
| form when minerals crystallize directly from water | chemical rocks |
| sedimentary rock that was formed by organisms or contains the remains of organisms | biochemical rock |
| any process that affects the structure or composition of a rock in a solid state as result of changes in temperature, pressure, or the addition of chemical fluids | metamorphism |
| permanent change in shape by bending and folding | plastic deformation |
| contain parallel layers of flat and elongated minerals | foliated rocks |
| metamorphic rocks that have mineral grains with a random, interlocking texture | nonfoliated rocks |
| magma comes in contact with existing rock, and its thermal energy and gasses interact with the surrounding rock, forming new metamorphic rock | contact metamorphism |
| the formation of metamorphic rock bodies that are hundreds of square kilometers in size | regional metamorphism |
