Geography - rock formation rock cycle - GCSE

  1. 1. This Presentation is About: Igneous Rocks Sedimentary Rocks Metamorphic Rocks
  2. 2. Igneous Rock Igneous rock is formed from molten rock that hardened into a solid state.
  3. 3. Forming Igneous Rocks
  4. 4. Types of Igneous Rock • There are two types of igneous rock: Extrusive, which forms from lava that hardens on Earth’s surface. Intrusive, which forms from magma that hardens beneath Earth’s surface.
  5. 5. Extrusive Rock Lava Cools Quickly and Hardens into Extrusive Rock Molten Rock Above Surface (Lava)
  6. 6. Extrusive rock formation - cooling lava
  7. 7. Intrusive Rock Molten Rock Below Surface (Magma) When the Volcano Stops Erupting, the Magma Cools Slowly and Hardens into Intrusive Rock
  8. 8. Igneous Rock Types Granite Coarse grained
  9. 9. Sedimentary Rock Sedimentary rock is made of sediment that has been deposited, compacted, and cemented.
  10. 10. Sedimentary Rock - layers
  11. 11. Types of Sedimentary Rock • There are three types of sedimentary rock: Clastic, which is formed when rock fragments are squeezed together. Organic, which forms when the remains of plants and animals are deposited in thick layers. Chemical, which forms when minerals that are dissolved in a solution crystallize.
  12. 12. Sedimentary Rock
  13. 13. Metamorphic Rock Metamorphic rock is any rock that has gone under immense heat and pressure to transform into another rock.
  14. 14. How Metamorphic Rocks are Formed HEAT AND PRESSURE Earth’s Crust Magma Rock Layers
  15. 15. Metamorphic Rock Forming
  16. 16. Types of Metamorphic Rock • There are two types of Metamorphic rock: Foliated, which is when the rock grains are arranged in parallel layers or bands. Nonfoliated, which is when the rock grains are arranged randomly.
  17. 17. Foliated Rock
  18. 18. Nonfoliated Rock
  19. 19. Metamorphic Rock
  20. 20. Foliated Metamorphic Rock –Slate
  21. 21. Non-Foliated Metamorphic Rock - Marble
  22. 22. The Rock Cycle
  23. 23. The Rock Cycle
