  3. 3. What Is A Metamorphic Rock? <ul><li>A metamorphic rock is a rock that has been changed in shape. </li></ul><ul><li>Before the components of a metamorphic rocks are Igneous, Sedimentary, Metamorphic or other types of rocks pushed together by gravity and pressure. </li></ul><ul><li>The texture might even have no sign of its components, but will have crystallizations. </li></ul>
  4. 4. One Kind Of Metamorphic Rock- Marble <ul><li>Marble is a metamorphic rock that comes from metamorphosed limestone, calcite, or dolomite. </li></ul><ul><li>Color: Various but usually gray or white. </li></ul><ul><li>Marble is usually used for making sculptures and flooring. </li></ul><ul><li>Marble tends to be considered an elegant material.

  8. 8. Glossary <ul><li>Metamorphic- A metamorphic rock is a rock that has been changed in shape. </li></ul><ul><li>Heat- Heat is when something turns very hot and melts into hot liquid. </li></ul><ul><li>Crystallization- When hot liquid freezes. This hardens into different shapes and lusters. </li></ul><ul><li>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. </li></ul>
  9. 10. Test <ul><li>How is a metamorphic rock formed? </li></ul><ul><li>Gravity and pressure </li></ul><ul><li>List two properties of a metamorphic rock. </li></ul><ul><li>Sculptures, flooring and statues </li></ul><ul><li>What is marble used for? </li></ul><ul><li>Sculptures and flooring </li></ul><ul><li>What is a metamorphic rock? </li></ul><ul><li>Rocks that are Squished together. </li></ul>
