1. SCI TIP Describe the differences of Sand, Silt, & Clay
Which sediment travels by wind furthest? Why?
What is a Loess Deposit? How did it get there?

2. SCI TIP Describe Glacial EROSION. Describe Glacial DEPOSITION.
What is a TOPO MAP? How does it work?
List 2 facts about WIND EROSION.
What is a MASS MOVEMENT?
List and describe 2.

4. MASS MOVEMENTS

5. MASS MOVEMENTS

9. MASS MOVEMENT
mass movement, is the geomorphic process by which soil and rock move down slope under the force of gravity.

12. When the gravitational force acting on a slope exceeds its resisting force, slope failure (mass wasting) occurs.
Can be FAST or slow

13. Triggers of Mass Movements
Rain
Spring Thaws
Volcanic Eruptions
Earthquakes
MOST COMMON?

15. Rockfall/Slide Fall of rock from steep cliff.
Most rapid kind of mass movement)
Sediment ranges in size from small fragments to large BOULDERS.

19. Landslide
Sudden movement of masses of loose rock and soil down the slope of a hill, mountain, or cliff.

23. Mudflow/Lahar Rapid movement of large masses of mud.
Lahar: volcanic eruption involved.
Occur in dry/Mountainous regions that receive large amounts of rainfall in a short period of time.

24. MUDFLOW/LAHAR

31. Slump
Sliding of one large piece of soil down a hillside.

41. Creep
Slow downhill movement of weathered rock material.

42. Creep

43. Some visible effects of creep

44. CREEP

45. CREEP

50. Solifluction
Slow down-hill flow of wet, muddy topsoil over frozen clay-rich subsoil.
