 8.1 Mass Movements 8.1 Mass Movements Presentation Transcript

  • Chapter 8.1 Mass Movements at Earth’s Surface Pages 181-190
  • Goal 1 Identify the 5 factors that affect mass movements
    • Mass movements
      • the down-slope movement of loose sediments and weathered rock resulting from the pull of gravity
    View slide
    • Slope angle
    View slide
    • Material weight
    • Material resistance to movement
    • Trigger
    • Water
  • Goal 2 Recognize and describe types of mass movements
    • Creep
      • Slow, few cm/year
      • All slopes
      • Tilted objects
      • Broken construction
      • Overtake roads, sidewalks
    • Flows
      • Thick liquid
      • Vibration trigger
      • Rain trigger in arid area
      • Mixing
      • Earth flow = slow
      • Mud flow =Fast
    • Slides
      • Rapid
      • Block of material
      • Little mixing
      • Trigger = earthquake
  •  
      • Rockslide
      • Rockslide
      • Landslide
    • Check out this link to see a video of a landslide in Japan
    • http://nwgeoscience.com/kelso/
    • Slump
    • Type of landslide
    • Materials “rotate”
    • Curved slide
  •  
  •  
  •  
    • Avalanche
      • Snow
      • Slope 35°
      • Melt – refreeze
      • More snow
      • Vibration trigger
  •  
  •  
    • Rock Falls
      • High elevations
      • Road cuts
      • Rocky shorelines
      • Weathered Rock
      • Falls
