Presentation Transcript

  1. Metamorphic Rocks (pages 110–112) Types of Metamorphic Rocks (pages 110–111) 

  2. Word Wall • Foliated rock • Marble • Slate

  3. Objective 1 – Describe the conditions under which metamorphic rocks form. Objective 2 – Identify the ways in which geologists classify metamorphic rocks. Objective 3 – Explain how metamorphic rocks are used.

  4. Objective 1 – how metamorphic rocks form Heat and pressure beneath the earth’s surface can change any rock into metamorphic rock.

  5. Objective 1 – what changes? • Appearance • Texture • Crystal structure • Mineral content • Metamorphic rock can form from igneous, sedimentary, or other metamorphic rock.

  6. Forces inside the Earth can push the rock down toward the heat of the mantle.Pockets of magma rising through the crust also provide heat that can produce metamorphic rocks.

  7. The deeper a rock is buried, the greater the pressure on that rock.Under high temperature and pressure many times greater than at Earth’s surface, the minerals in a rock can be changed into other minerals.The rock has become metamorphic.

  8. Objective 2Metamorphic rocks are classified by their grain patterns.

  9. Foliated rocks are metamorphic rocks with their grains lined up in layers. Foliated rocks split into flat pieces.

  10. Slate is a foliated rock.

  11. Nonfoliated rocks are metamorphic rocks with their grains scattered at random.

  12. Nonfoliated rocks do not split into flat pieces.

  13. Marble is a nonfoliated rock.

  14. foliated Non-foliated Grains scattered at random Grains lined up in layers Kind of metamorphic rock

  15. Metamorphic rocks are classified by their patterns. grain

  16. Uses of Metamorphic Rock (page 112)

  17. Objective 3 – how metamorphic rocks are usedCertain metamorphic rocks are important materials for building and sculpture.

  18. Marble and slate are two of the most useful metamorphic rocks.

  19. Marble can be cut, carved, and polished. Marble is used for buildings and statues.

  20. Slate splits easily into flat pieces. Slate is used for floors, roofs, and chalkboards.

  21. Circle the letter of each sentence that is true about marble. a. Marble is a kind of sedimentary rock. b. Marble is used forbuildings. c. Marble can be carved.

  22. true or false? Slate is good for chalkboards because it splits easily into flat pieces. true
