dissolved in water as rocks erode
Series of processes that change one type of rock into another type of rock
Volcanic material erupts and cools and crystallizes on Earth’s surface
Rock that forms when lava forms too quickly to form crystals

between grains

fragments

When minerals crystallize directly from water.
Sedimentary rock that was formed by organisms or contains the remains of
organisms.
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 or chemical fluids.
Permanent change in shape by ending and folding
Contain parallel layers of flat and elongated minerals.
