Lecture9 rockcycle Lecture9 rockcycle Presentation Transcript

  • The Rock Cycle
  • Quiz 3!
  • Rock cycle metamorphic rocks igneous rocks sedimentary rocks important to note rock types, processes, intermediary states, and shortcuts
  •  
  •  
  • IGNEOUS ROCK
  • Magma cools & solidifies Igneous Rock The Rock Cycle
  • Weathering- Surface processes that physically disrupt and chemically change rocks
  • Transport of Weathered Materials
  • Sediment Deposition
  • Magma cools & solidifies Igneous Rock Weathering Transport & Deposition Sediment The Rock Cycle
  • SEDIMENTARY ROCK Lithification 1 mm
  • cools & solidifies Igneous Rock Weathering Transport & Deposition Sedimentary Rock Lithification The Rock Cycle Magma Sediment
  • Sedimentary rocks exposed in the Canadian Rockies
  • cools & solidifies Igneous Rock Weathering Transport & Deposition Sedimentary Rock Lithification Weathering Transport & Deposition The Rock Cycle Magma Sediment
  • METAMORPHIC ROCKS
  • cools & solidifies Igneous Rock Weathering Transport & Deposition Sedimentary Rock Lithification Weathering Transport & Deposition Metamorphic Rock Heat & Pressure The Rock Cycle Heat & Pressure Magma Sediment
  • Limestone- sedimentary rock Marble- metamorphic rock
  • How is Turkey Like a Metamorphic Rock? Transformed in the Solid State
  • If there is melting , then it’s not metamorphism
  • The Rock Cycle cools & solidifies Igneous Rock Weathering Transport & Deposition Sedimentary Rock Lithification Weathering Transport & Deposition Metamorphic Rock Heat & Pressure melting Heat & Pressure melting Magma Sediment melting

    • Earth’s
    • Internal structure
    • Core (2200 mi)
    • Mantle (1800 mi)
    • Crust (5-25 mi)
  • Inner Core Mantle Crust Outer core
    • solid (due to very high pressure)
    • composed of Fe & Ni
    • 7000-9000 °F
  • Outer Core
    • molten
    • composed of Fe & Ni
    • 5400-7000 °F
    • generates magnetic field due to convective flow
    Inner core Mantle Crust
  • Mantle Inner core Crust Outer core
    • majority of Earth’s volume
    • composed of oxides of Fe, Si, and Mg
    • data from volcanic material & experimental work
    • - 3300- 5100 °F
    • - divided into 3 zones
  • 3 mantle zones
    • Uppermost mantle
      • - rigid
    • Asthenosphere
      • - plastic
      • - moves indpt of lithosphere
    • Mesosphere
      • - rigid
    Mesosphere Asthenosphere Uppermost mantle lithosphere mantle
  • Crust
    • thin, brittle layer
    • contains continents & ocean basins
    • abundant elements: O, Si, Al, and Fe
    • Moho = discontinuity between crust & mantle
    • Lithosphere = crust +
    • uppermost mantle
    Mantle Outer core Inner core
  • Continental vs. oceanic crust Continental Oceanic Thickness thick thin Composition granite basalt Elements Si & Al Fe & Mg Density low high Age old young
  • Isostasy
    • maintenance of hydrostatic equilibrium of crust
    • -AKA buoyancy
    • adding weight to crust = sink
    • removing weight = rise
  • Excel Demo
