  • 3. What Is A Metamorphic Rock?
    • A metamorphic rock is a rock that has been changed in shape.
    • Before the components of a metamorphic rocks are Igneous, Sedimentary, Metamorphic or other types of rocks pushed together by gravity and pressure.
    • The texture might even have no sign of its components, but will have crystallizations.
  • 4. One Kind Of Metamorphic Rock- Marble
    • Marble is a metamorphic rock that comes from metamorphosed limestone, calcite, or dolomite.
    • Color: Various but usually gray or white.
    • Marble is usually used for making sculptures and flooring.
    • Marble tends to be considered an elegant material. It is also tied closely to the classical Greek and Roman periods. A relatively expensive, and difficult to maintain stone, it is most often used in delicate and upscale applications.
  • 5. Another Kind Of Metamorphic Rock- Quartzite
    • Quartzite is a coarse-grained metamorphic rock derived from sandstone.
    • Color: Usually white, light gray, yellowish, or light brown.
    • Quartzite is used for floorings, construction materials and is part of the ingredients in glass.
    • It has a uniform texture and is very hard, 7 on the Mo's Scale.
  • 6. Last Kind Of Metamorphic Rock That We Will Define-Gneiss
    • Gneiss is a medium to course grained metamorphic rock.
    • Color: Usually black and white.
    • Gneiss is used for gravestones, and flooring material.
    • Gneiss is found in New England, the Piedmont (Part of North America), the Adirondacks, and the Rocky Mts. Some gneisses are used as facing stone on buildings.
  • 7. Properties Of A Metamorphic Rock
    • Metamorphic rocks are composed of Ingenious, Sedimentary, Metamorphic or any other kind of rock pushed together by gravity, heat, and pressure.
  • 8. Glossary
    • Metamorphic- A metamorphic rock is a rock that has been changed in shape.
    • Heat- Heat is when something turns very hot and melts into hot liquid.
    • Crystallization- When hot liquid freezes. This hardens into different shapes and lusters.
    • Pressure- Is when something or someone is using much force to push or move an object and is the friction from pushing or moving the object.
