9 25 rock cycle

  1. 1. Standard & Elements • S6E5. Students will investigate the scientific view of how the earth’s surface is formed. – c. Classify rocks by their process of formation. – d. Describe processes that change rocks and the surface of the earth. Cause and Effect in the Rock Cycle
  2. 2. Directions: • Read each slide • Fill in any blanks using the underlined or highlighted words. • Finished go back watch the Study Jam video then explore other rock cycle activities. 2
  3. 3. Rocks You already know… • Rocks are naturally occurring combinations of minerals. • Most consist of two or more different minerals. • Rocks are classified according to how they were formed & mineral composition.
  4. 4. You already know…. All rocks fit into one of three classifications. (Products) • Igneous – formed from magma or lava. • Sedimentary – formed from compressed sediment. • Metamorphic – formed by heat and pressure.
  5. 5. The Rock Cycle • Rock families change because of different processes. (eg: weathering; cementation; heat and pressure; and melting.) • New rocks are constantly being formed by old rock material. • This continuous change is called the Rock Cycle. • All rocks go through this cycle.
  6. 6. Types of Changes (Processes) • Weathering and Erosion • Compaction and Cementation • Cooling • Melting • Heat and Pressure • These changes can take place in various order and combinations.
  7. 7. The Rock Cycle Thinking about relationships among the major rock groups/ Fill in the blanks with these processes & products
  8. 8. Fig. 2.9 MAGMAStart here:
  9. 9. 9 MAGMA Crystallization IGNEOUS Next answer, please read each slide because they will explain the process or product
  10. 10. 10 MAGMA IGNEOUS Plutonic Crystallization
  11. 11. 11 MAGMA Volcanic IGNEOUS Plutonic Crystallization
  12. 12. 12 MAGMA Volcanic IGNEOUS Plutonic Uplift Crystallization Weathering
  13. 13. 13 MAGMA Volcanic IGNEOUS Plutonic SEDIMENT Uplift Crystallization Weathering SEDIMENT
  14. 14. 14 MAGMA Volcanic IGNEOUS Plutonic SEDIMENT SEDIMENTARY Uplift Crystallization Weathering Erosion Transport Deposition
  15. 15. 15 MAGMA Volcanic IGNEOUS Plutonic SEDIMENT SEDIMENTARY Uplift Crystallization Weathering Erosion Transport Deposition
  16. 16. 16 MAGMA Volcanic IGNEOUS Plutonic SEDIMENT SEDIMENTARY METAMORPHIC Uplift Burial Increased P&T Crystallization Weathering Erosion Transport Deposition
  17. 17. 17 MAGMA Volcanic IGNEOUS Plutonic SEDIMENT SEDIMENTARY METAMORPHIC Uplift Burial Increased P&T Melting Crystallization Weathering Erosion Transport Deposition Can you see any shortcuts?
  18. 18. 18 MAGMA Volcanic IGNEOUS Plutonic SEDIMENT SEDIMENTARY METAMORPHIC Uplift Burial Increased P&T Melting Crystallization Weathering Erosion Transport Deposition
  19. 19. • The rock cycle demonstrates the relationships among the three major rock groups • It is powered by the interior heat of the Earth • As well as earth’s momentum and… • The energy from the sun • It involves processes on the Earth’s surface as well as the Earth’s interior • It connects the “hydrologic cycle” with the “tectonic cycle”. In Conclusion…
  20. 20. Rock Cycle (example) Write each step down in order 1. As magma cools, it may form an igneous rock called granite. 2. Granite can be broken down by weathering to form tiny pieces called sediment. 3. The sediment will settle (deposition). Then sediments get compacted and cement together to form Sedimentary rocks.
  21. 21. 4. If the Sedimentary rock is exposed to heat and pressure, it will form a Metamorphic rock. 5. The new Metamorphic rock could then melt and cool to form an igneous rock or it could erode and form a different Sedimentary rock. The Rock Cycle is NOT a one way process.
