'''Metamorphic rocks''' are created when existing [[Igneous_rock|igneous]] or [[Sedimentary_rock|sedimentary]] [[rock|rocks]] are squashed, stretched and/or cooked and change their appearance and [[mineral]] composition.
Some metamorphic rocks have [[course-grained]] minerals that occur in wavy bands. Others are very [[fine-grained]]. Most are hard and difficult to break.
