The Rock Cycle

  1. 1. By Morgan Brandt
  2. 2. What is a rock?• Solid• Occurs through nature• Made up of minerals Info from: http://www.rocksandminerals4u.com/what_is_a_rock.html
  3. 3. Characteristics of the Rock Cycle• Three types of rocks – Igneous – Sedimentary – Metamorphic Info from: http://www.cotf.edu/ete/modules/msese/earthsysflr/rock.html
  4. 4. Igneous Rock• Formed from molten rock becoming solid• Molten rock – Called intrusive rock because it’s magma when under the Earth’s surface • Magma is hot liquid from minerals – Called extrusive rock because it’s lava when above the Earth’s surfaceInfo from:http://www.cotf.edu/ete/modules/msese/earthsysflr/rock.htmlhttp://www.windows2universe.org/earth/geology/ig_intro.htmlPicture from: http://www.rocksandminerals4u.com/igneous_rocks.html
  5. 5. Examples of Igneous Rock• Pumice• Obsidian• RhyoliteInfo and pictures from: http://www.rocksandminerals4u.com/example_of_igneous_rocks.html
  6. 6. Sedimentary Rocks• Sediment is broken bits of rock• These rocks form at: – Rivers – Beaches – The ocean – And wherever else sediment collectsInfo found at : http://www.windows2universe.org/earth/geology/sed_intro.html
  7. 7. Examples of Sedimentary Rock• Sandstone• Siltstone• Shale Info and pictures found at: http://www.rocksandminerals4u.com/sedimentary.html
  8. 8. Metamorphic Rock• Formed by high pressure and high temperature – Possibly where tectonic plates meet• Chemically change – Mineral crystals alter Info and picture from: http://www.windows2universe.org/earth/geology/meta_intro.html
  9. 9. Examples of Metamorphic Rock• Quartzite• Marble• Slate Pictures found at: http://www.rocksandminerals4u.com/metamorphic.html
  10. 10. How It WorksPicture from:http://www.cotf.edu/ete/modules/msese/earthsysflr/rock.html
  11. 11. How are the rocks related?• Igneous rock – Can change into sedimentary or metamorphic• Sedimentary rock – Can change into igneous or metamorphic• Metamorphic rock – Can change into igneous or sedimentary Info from: http://www.cotf.edu/ete/modules/msese/earthsysflr/rock.html
  12. 12. Changes in Igneous Rock• How does it turn into sedimentary? – Sediments come from weathering and erosion of igneous rock – Sediments compact and cement into sedimentary rock Info from: http://www.cotf.edu/ete/modules/msese/earthsysflr/rock.html
  13. 13. Changes in Igneous Rock• How does it turn into metamorphic? – High heat and pressure Info from: http://www.cotf.edu/ete/modules/msese/earthsysflr/rock.html
  14. 14. Changes in Sedimentary Rock • How does it become igneous rock? – By weathering and erosion • How does it become metamorphic? – High heat and pressure from EarthInfo from: http://www.cotf.edu/ete/modules/msese/earthsysflr/rock.html
  15. 15. Changes in Metamorphic Rock• How does it become igneous rock? – Melting into magma then cooling• How does it become sedimentary rock? – Eroding into sediments and then being compactedInfo and picture from: http://www.cotf.edu/ete/modules/msese/earthsysflr/rock.html
  16. 16. Why are rocks important? • Fossils! • Remind us of the Earth changing – Heating, pressure, cooling • Around for thousands of years – Older than you!Info from: http://www.rocksandminerals4u.com/what_is_a_rock.html
  17. 17. It’s also important for… Rock, Paper, Scissors!
  18. 18. The End
