Metamorphic Rocks
1. Heat/pressure or chemical processes
cause physical or chemical changes.
2. Old sedimentary, igneous or
metamorphic rock changing to new
metamorphic rock.
3. Below Earth’s surface.
Types of Rocks
1. Magma and hot liquids causes
changes in rock.
2. Small areas of rock “contacted”
directly with magma
3. Large “regional” areas of rock
Surface of Earth’s crust
Processes forming igneous or
sedimentary rocks.
changed by heat and pressure from
movement and collisions of crust.
4. Foliation or non-foliation
5. Forms deep within crust or just below
Earth’s surface.
Metamorphic rocks are a type of rock in which heat, pressure and/or liquid (magma) chemically changes
the composition of previous sedimentary, igneous or metamorphic rocks. Size, shape and arrangement of
crystals can vary.
