Transcript of "Rocks"

  1. 1. This Presentation is About:<br />Igneous Rocks<br />Sedimentary Rocks<br />Metamorphic Rocks<br />
  2. 2. Igneous Rock<br />Igneous rock is formed from molten rock that hardened into a solid state.<br />
  3. 3. Types of Igneous Rock<br />There are two types of igneous rock:<br /><ul><li>Extrusive, which forms from lava that hardens on Earth’s surface.
  4. 4. Intrusive, which forms from magma that hardens beneath Earth’s surface.</li></li></ul><li>Lava Cools Quickly and Hardens into Extrusive Rock<br />Molten Rock Above Surface (Lava)<br />Extrusive Rock<br />
  5. 5. Molten Rock Below Surface (Magma)<br />Intrusive Rock<br />When the Volcano Stops Erupting, the Magma Cools Slowly and Hardens into Intrusive Rock<br />
  6. 6. Examples<br />Intrusive<br /><ul><li>Granite
  7. 7. Porphyry
  8. 8. Pegmatite</li></ul>Extrusive<br /><ul><li>Basalt
  9. 9. Obsidian
  10. 10. Rhyolite</li></li></ul><li>Sedimentary Rock<br />Sedimentary rock is made of sediment that has been deposited, compacted, and cemented.<br />
  11. 11. Types of Sedimentary Rock<br />There are three types of sedimentary rock:<br /><ul><li>Clastic, which is formed when rock fragments are squeezed together.
  12. 12. Organic, which forms when the remains of plants and animals are deposited in thick layers.
  13. 13. Chemical, which forms when minerals that are dissolved in a solution crystallize.</li></li></ul><li>Clastic Rock <br /> Rock Fragments Squeezed Together <br />Scattered Rock Fragments <br />
  14. 14. Organic Rock<br />Layer of Organic Material Above Soil<br />Organic Material gets Covered with Soil and Compacts Together<br />Compacted Organic Material Eventually Hardens into Rock<br />Soil<br />
  15. 15. Chemical Rock<br />Minerals Get Deposited in Water<br />Minerals Dissolve in Water<br />Minerals Crystallize<br />
  16. 16. Examples<br />Clastic<br /><ul><li>Shale
  17. 17. Sandstone
  18. 18. Conglomerate
  19. 19. Breccia</li></ul>Organic<br /><ul><li>Coal
  20. 20. Limestone</li></ul>Chemical<br /><ul><li>Limestone</li></li></ul><li>Metamorphic Rock<br /> Metamorphic rock is any rock that has gone under immense heat and pressure to transform into another rock.<br />
  21. 21. Types of Metamorphic Rock<br />There are two types of Metamorphic rock:<br /><ul><li>Foliated, which is when the rock grains are arranged in parallel layers or bands.
  22. 22. Nonfoliated, which is when the rock grains are arranged randomly.</li></li></ul><li>Foliated Rock<br />
  23. 23. Nonfoliated Rock<br />
  24. 24. How Metamorphic Rocks are Formed<br />HEAT AND PRESSURE<br />Earth’s Crust<br />Magma<br />Rock Layers<br />
  25. 25. Examples<br />Foliated<br /><ul><li>Slate
  26. 26. Schist
  27. 27. Gneiss</li></ul>Nonfoliated<br /><ul><li>Marble
  28. 28. Quartzite</li></li></ul><li>Amber Fox Productions<br />Text: Amber Fox<br />Illustrations: Amber Fox<br />Animation: Amber Fox<br />Sound: Amber Fox<br />
