I’m working on a geology question and need guidance to help me understand better.
Question 1
The maximum angle at which a material is stable is called
Angle of Rest
Shear Stress
Shear Strength
Angle of Repose
Question 2
Any amount of water in soil or rock will tend to reduce friction and cause mass movement to occur.Group of answer choices
True
False
Question 3
Which of the following will tend to reduce the risk of mass movement?
Earthquakes
Added weight to a slope
Large amounts of water in soil
Vegetation
Question 4
Rapid mass movement in which the material is not in contact with the ground is called.
Flow
Rockfall
Rockslide
Landslide
Question 5
Highway roadcuts can lead to mass movement because
weight is removed.
The roadcut is less than the angle of repose
The roadcut increases weight on a slope
The roadcut exceeds the angle of repose
Question 6
Building a house at the top of a steep slope may contribute to mass movement because
of leaking water from domestic uses
all of these answers are correct
the house adds weight to the slope
addition of water from irrigation
Question 7
When a cohesive section of rock slips along a plane, it is called a
slide
fall
slump
flow
Question 8
A chaotic, incoherent movement of soil, rock, trees, and other particles down slope is called a
debris slide
debris fall
debris flow
rock fall
Question 9
Planting vegetation on an unstable slope may help to stabilize the slope because
roots add water to slope
weight is removed
additional weight is added
roots act as an anchor to keep soil in place
Question 10
Evidence for past mass movements includes
slopes free of vegetation
talus at the base of a cliff
all of these answers are correct
tilted tree trunks
Question 11
The downslope pull tending to cause mass movement is called
Shear Strength
Shear stress
Friction
Repose
