  1. The Rock Cycle

  2. D21 Explain how internal energy of the Earth causes matter to cycle through the magma and the solid earth.

  3. The Rock Cycle

  4. Three Major Rock Groups • Igneous • Sedimentary • Metamorphic

  5. Major Rock Groups Igneous • Formed from melted or molten rock There are two types of igneous rock • Plutonic or Intrusive • This forms from magma which undergoes slow cooling and crystallization below the surface • Volcanic or Extrusive • This forms from lava which undergoes quick cooling at the surface

  6. Igneous Rocks

  7. Igneous Rocks Pumice Obsidian

  8. Major Rock Groups Sedimentary • These rocks form from small pieces of materials which collect, and over time become cemented together as rock • These are formed at the Earth’s surface Two Types • Clastic • These form from mineral fragments or clays • Chemical • These form from crystals or biochemical precipitates

  9. Sedimentary Rocks

  10. Sedimentary Rocks

  11. Major Rock Groups • Metamorphic • These types of rocks have been changed by pressure, temperature and fluids.

  15. IGNEOUS Plutonic Crystallization MAGMA

  16. Volcanic IGNEOUS Plutonic Crystallization MAGMA

  17. Weathering Volcanic IGNEOUS Plutonic Crystallization Uplift MAGMA

  18. SEDIMENT SEDIMENT Weathering Volcanic IGNEOUS Plutonic Crystallization Cooling Uplift MAGMA

  19. SEDIMENT SEDIMENT Weathering Erosion & Transport & Pressure Volcanic IGNEOUS Plutonic Crystallization Cooling Water Uplift MAGMA Wind Ice Gravity

  20. Erosion SEDIMENT Weathering Lithification = Cementation + Compaction Transport Deposition Volcanic IGNEOUS Plutonic SEDIMENTARY Crystallization Cooling Uplift MAGMA

  21. Erosion SEDIMENT Weathering Transport Deposition Volcanic IGNEOUS Plutonic SEDIMENTARY Increased P&T METAMORPHIC Crystallization Cooling Burial Uplift MAGMA

  22. Erosion SEDIMENT Weathering Transport Deposition Volcanic IGNEOUS Plutonic Can you see any shortcuts? SEDIMENTARY Increased P&T METAMORPHIC Crystallization Cooling Melting Burial Uplift MAGMA

  24. In Conclusion… • The rock cycle demonstrates the relationships among the three major rock groups • It is powered by the interior heat of the Earth • It involves processes on the Earth’s surface as well as the Earth’s interior
