GEOL 101 CHAPTER 10 EXAM
QUESTIONS WITH COMPLETE
SOLUTIONS
When sediment accumulates, the angle of repose can be increased by changing which
of the following conditions? - Answer- Slight addition of water to the sediment
You will explore the differences in mass movement types based on their unique
characteristics. Match each key term to the appropriate sentence. - Answer- 1. A mass
movement in which a cohesive block of earth or rock slips downhill relatively quickly in
one piece along a zone of weakness is called a SLIDE.
2. Mass movements that move blocks of materials and unconsolidated materials down a
curved surface creating scarps on a slope are known as SLUMP.
3. When large rocks become dislodged and drop down a steep slope, the mass
movement is called a FALL.
4. CREEPS are very gradual mass movements in which the whole slope moves
downhill slowly.
5. When unconsolidated material moves downslope as a viscous fluid it is called a
FLOW.
You will label the five types of mass wasting in terms of the materials they carry. Drag
the appropriate labels to their respective targets - Answer- -SLUMP MATERIAL: blocks
of materials or unconsolidated sediments along a curved surface
-SLIDE MATERIAL: blocks of bedrock broken loose and sliding downhill
-FLOW MATERIAL: fined-grained materials that can easily flow like a liquid
-CREEP MATERIAL: pieces of rock and loose sediments gradually transported
downhill; movement of such material is unseen
-FALL MATERIAL: boulders on a rocky cliff
The Gros Ventre slide is evident today by __________. - Answer- a scar, runout area,
and landslide debris filling the valley
Which of the following is a reason the Gros Ventre rockslide took place? - Answer-
Because the river eroded material at the valley base, there was no support of the
material upslope.
A __________ acted as a sliding surface across which material moved downhill during
Gros Ventre Slide. - Answer- clay layer
Heavy rainfall caused the clay to lubricate and the sandstone to become
____________. - Answer- saturated and heavy
