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 |
