Heat, pressure and stress can also change some igneous or sedimentary rocks into other kinds of rocks. This fact-filled book describes the process that turns limestone into marble, shale into slate, and granite into gneiss. Metamorphic rocks are often used as materials for floors, roofs, and counter tops because of their beauty.
