What are the two criteria for classifying mass wasting events?
What are 'TYPE OF MATERIAL' and 'TYPE OF MOVEMENT'
What type of structure is shown in the image below?
What is 'SYNCLINE'
Weathering and erosion of rocks creates a material that when moistened, is beloved by pigs. When it's relatively dry, it's vital for all organisms on Earth.
What is 'SOIL'
What type of slope failure involves poorly consolidated material and a curved rupture surface?
What is 'ROTATIONAL SLIDE'
Also accepted 'ROTATIONAL SLUMP'
On which plate boundaries do the largest magnitude earthquakes occur?
What are 'CONVERGENT BOUNDARIES' also accepted, 'SUBDUCTION ZONES'
What type of movement is associated with cycles of freeze/thaw?
What is 'CREEP'
What type of fault, shown below, is associated with tensional stress along divergent boundaries?
What is 'NORMAL FAULT'
Which mineral--commonly associated with high temperatures--breaks down first in the Goldrich Stability Series? Hint: it's also the name of TA Mary's dog.
What is 'OLIVINE'
What type of slope failure is associated with weaknesses along a planar surface
What is 'TRANSLATIONAL SLIDE'
What type of fault was responsible for the 1906 Magnitude ~7.9 earthquake in San Francisco?
What is 'STRIKE-SLIP FAULT'
Which of the following is NOT a mechanism of geological over-steepening?
1. Sea cliff erosion
2. Rapid uplift/faulting
3. Stream bank undercutting
4. Basin subsidence
What is '4. BASIN SUBSIDENCE'
Which type of fold, commonly found on the Colorado Plateau, is associated with movement along reverse faults?
Fold exposed along the San Juan River, Utah
What is a 'MONOCLINE'
What type of weathering is occurring on this marble headstone?
What is 'CHEMICAL WEATHERING'
What type of mass wasting is characterized by high rates of speed and contains rock, debris, and AIR?
HINT: this is not a slump, slide, or slurry
What is 'ROCK AVALANCHE'
What earthquake scale requires data from multiple seismometer stations and considers rupture length, rupture offset, and the geology of the rupture zone?
What is 'MOMENT MAGNITUDE SCALE'
Which location is most likely to experience mass wasting?
1. Anchorage, Alaska
2. Topeka, Kansas
3. Moab, Utah
What is 'ANCHORAGE, ALASKA'
Which of the rock layers exposed on the surface is the oldest?
What is 'E'
What type of weathering is shown in the image below?
What is 'DIFFERENTIAL WEATHERING'
The photo below shows the result of thawing tundra near Holmes Creek, Alaska. What type of mass wasting is occurring here?
What is 'ROTATIONAL SLUMP'
What type of quantitative scale is best for measuring shallow earthquakes along strike-slip faults?
What is 'THE RICHTER SCALE'
Which location below exceeds the angle of repose and is most likely to fail?
What is 'D'
Cache Valley is formed by two normal faults. What is the down-dropped hanging wall between the two footwalls called?
What type of weathering is shown below?
What type of slurry flow involves very rapidly moving masses of fine-grained particles and water?
What is 'MUD FLOW'
What is the primary hazard associated with megathrust earthquakes?
What are 'TSUNAMI'
What are the three triggers of mass wasting events?

Which segment of the Wasatch Fault is most likely to rupture within the next 50 years?
What is the 'SALT LAKE CITY SEGMENT'
Also accepted the 'BRIGHAM CITY SEGMENT'
Differential weathering is explained as different lithologic units breaking down at different rates.
Which lithologic unit in the image below is weathering faster, sandstone or shale?
What is 'SHALE'
What type of mass wasting event caused the disaster at the Vaiont Dam in Italy?
What is 'ROCK SLIDE'
