  - - - Metamorphic means change under extreme heat or pressure
      - When sedimentary or igneous rocks are put under great heat or pressure they change to metamorphic rocks
    - - Most metamorphic rocks form when rock in fold mountains is heated (not metal) by magma. The magma is in batholiths. When rocks touches the magma or lies very close to the magma, due to intense heat it changes to another rock type
      - Most of Irelands metamorphic rocks were formed in the Caledonian mountains about 400 million years ago
