Transcript

  • 1. 5.3 Mass Movements
  • 2. Mass movement• The downslope movement of rock, regolith, and soil under the direct influence of gravity
  • 3. rockfall• Occurs when rocks or rock fragments fall freely through the air; common on steep slopes
  • 4. rockslide• Occurs when a mass of rock slides rapidly downslope along planes of weakness
  • 5. slump• The downward slipping of a mass of rock or unconsolidated material moving as
  • 6. mudflow• Quickly moving downhill flow of soil and rock fragments containing a large amount of water
  • 7. earthflow• Slow- moving downslope movement of water- saturated, clay-rich sediment, most characteristics of humid regions
  • 8. Creep• The slow downhill movement of soil and regolith
  • 9. Key Concept• The transfer of rock and soil downslope due to gravity is called mass movements.
  • 10. Key Concept• Among the factors that commonly trigger mass movements are saturation of surface materials with water, oversteepening of slopes, removal of vegetation, and earthquakes.
  • 11. Key Concept• Geologists classify mass movements based on the kind of material that moves, how it moves, and the speed of movement.
