Metamorphic rocks are created when existing igneous or sedimentary 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.
