Metamorphic Rocks

The rocks that make up our Earth are constantly moving and changing.  The three types of rocks are igneous, sedimentary, and metamorphic.  A metamorphic rock is Metamorphic Rocksformed when a sedimentary or igneous rock changes form because the temperature or pressure changes.  This change typically happens over time when the sedimentary or igneous rocks are buried beneath the earth’s surface.  The pressure from the layers of rocks and the high temperatures from deep in the Earth cause the minerals in the igneous and sedimentary rocks to change.  Many metamorphic rocks can be useful in our everyday lives.  Metamorphic rocks are used in jewelry, building and road materials and to make insulation.
