  2. Question 1 • What is the difference between weathering and erosion?

  3. Question 2 • How do glaciers move?

  4. Question 3 • What is a turn a river called?

  5. Question 4 • How can we increase likelihood of a mass movement.

  6. Answers • What is the difference between weathering and erosion? • Weathering breaks down and erosion moves. • How do glaciers move? • Gravity • What is a turn a river called? • Meander • How can we increase likelihood of a mass movement. • Water, people, Slope, mass, vegetation

  7. Mass wasting

  8. Vocabulary • Mass movement • Slump • Slide • Fall • Flow • Scarp • Vegetation

  9. Mass wasting • This is when the earth (soil/dirt) begins to move down hill • GRAVITY it driving force.

  10. Mass movements • Slump • This is when the land slides down equally. • Slide • This is when the land slides down not equally. • Fall- avalanche • The land falls • Flow • The land is liquefied and flows down.

  11. Things that will increase mass movements • Change water content • Change slope • Change mass • Change vegetation • Change human activity

  12. SLUMP

  13. Slide

  14. Fall

  15. Flow

  16. Which type of mass movement was this? • Slide, Fall, Slump, Fall??? • They called it the Tully Landslide. Was it a slide? • What caused this to happen?

  17. Tully Landslide ‘93 ¼ mile http://pubs.usgs.gov/of/1994/ofr-94-0615/tvstudy.htm
