Metamorphic rocks are formed from Parent rocksParent rocks (pre-existing rocks)

Parent rocks can be Igneous, sedimentary, Igneous, sedimentary, or other or other metamorphicmetamorphic rocks.

METAMORPHIC ROCKMETAMORPHIC ROCK META = CHANGE MORPH = FORM Metamorphism involves the

change in form or structure of a rock through heat and pressure.

3 ROCK TYPES: Igneous-formed from the cooling

and crystalization of magma Sedimentary-formed by the

compacting and cementation of layers of sediment

Metamorphic-formed by structural/chemical change due to heat and pressure
