broken pieces and fragments clasts
from when minerals crystallize directly from water chemical rocks
a 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 a 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 gases interact with the surrounding rock, forming new metamorphic rock contact metamorphism
