A)   Slump.
B)   Creep.
C)   Rock fall.
D)   Slide.

Question 3

B)   atmosphere; saturation of materials with water.
C)   biosphere; binding effects of vegetation.
D)   lithosphere; fracturing of rocks.

Question 4

Accepted Answer

On a slope, the force of gravity can be ...

Question 5

What is the cause of solifluction seen in very cold regions?

Accepted Answer

A)   Summer thawing of permafrost.
B)   Volcanic activity.
C)   Tsunamis.
D)   Movement on a fault.

Question 6

The principal factor driving mass movement is:

Accepted Answer

A)   lack of cohesion in a slope.
B)   friction.
C)   gravity.
D)   an unstable slope angle.

Question 7

On a slope susceptible to mass movement, the best way to reduce the movement potential is to:

Accepted Answer

A)   remove excess vegetation.
B)   increase the angle of the slope.
C)   freeze the slope with liquid nitrogen.
D)   reduce the water content of the slope.

Question 8

Solifluction is a comparatively rapid fo...

Question 9

All of the following indicate potential future mass movement EXCEPT:

Accepted Answer

A)   steam emitted from the local soil.
B)   displaced fence lines and bent tree trunks.
C)   water leakage from swimming pools.
D)   tilted utility poles and sagging power lines.

Question 10

Evidence of past slope failure is demonstrated by all of the following EXCEPT:

Accepted Answer

A)   gently sloping, vegetated hillsides.
B)   jumbles of slide and flow debris.
C)   talus slopes.
D)   landslide scars.

Question 11

All of the following can be used to predict an immediate mass- movement event EXCEPT:

Accepted Answer

A)   eyewitness observation of slowly accelerating creep.
B)   previous or historic occurrences of such events.
C)   strange animal behavior.
D)   electric slide detectors.

Question 12

Could the La Conchita mudslide have been predicted?

Accepted Answer

The La Conchita mudslide was predicted. ...

Question 13

Natural triggers of mass- movements include all of the following EXCEPT:

Accepted Answer

A)   torrential rains.
B)   earthquakes.
C)   intrusion of magma.
D)   volcanic eruptions.

Question 14

Which of the following statements about the role of water in mass movement is NOT true?

Accepted Answer

A)   A larger amount of water increases slope stability by increasing surface tension between adjacent particles.
B)   A small amount of water increases slope stability by aiding the growth of vegetation.
C)   A larger amount of water decreases slope stability by reducing friction between surface materials and the underlying material.
D)   A small amount of water somewhat increases slope stability because the water's surface tension attracts particles.

Question 15

Of the following types of mass movement, the fastest and slowest, respectively, are:

Accepted Answer

A)   slide and slump.
B)   fall and creep.
C)   slide and solifluction.
D)   fall and flow.
