21
Which geologic factor is most important for landfill site selection?
Discuss
Answer & Solution
Answer: Option C
Solution:
Permeability of the subsurface affects how leachate moves through the ground.Low-permeability layers are preferred to minimize groundwater contamination.Correct Answer: Permeability of the subsurface.
22
Which type of slope failure occurs along a curved surface?
Discuss
Answer & Solution
Answer: Option B
Solution:
Rotational slide involves movement of material along a concave-upward surface.It's common in homogeneous soils or weak rock masses.Correct Answer: Rotational slide.
23
What does a geological map typically show?
Discuss
Answer & Solution
Answer: Option C
Solution:
Geological maps depict types of rocks and their relationships, including faults and folds.Correct Answer: Distribution of rock units and structural features.
24
Which rock feature significantly reduces rock strength in slopes?
Discuss
Answer & Solution
Answer: Option B
Solution:
Joint spacing affects how rocks break and slide.Closer joints reduce rock mass strength and increase slope failure risk.Correct Answer: Joint spacing.
25
Which of the following best describes lithology?
Discuss
Answer & Solution
Answer: Option C
Solution:
Lithology refers to the physical and visual characteristics of rocks such as grain size, color, texture, and composition.Correct Answer: Physical characteristics of a rock.
26
Which geological term refers to a break in rock continuity due to tectonic forces?
Discuss
Answer & Solution
Answer: Option C
Solution:
Fault is a fracture or zone of fractures between two blocks of rock.Faults result from earth movements and often lead to earthquakes.Correct Answer: Fault.
27
What is the main function of a geological cross-section?
Discuss
Answer & Solution
Answer: Option C
Solution:
Geological cross-sections illustrate underground rock arrangements and structures in a vertical slice.Correct Answer: Represent a vertical profile of geological layers.
28
Which method is typically used to test rock compressive strength?
Discuss
Answer & Solution
Answer: Option A
Solution:
Point load test is a common method to estimate uniaxial compressive strength of rocks.Correct Answer: Point load test.
29
Which component is least considered in geological engineering site classification?
Discuss
Answer & Solution
Answer: Option D
Solution:
Astrological alignment is unrelated to engineering geology.Site classification considers physical and mechanical earth properties.Correct Answer: Astrological alignment.
30
What is a common indicator of karst terrain in geological investigation?
Discuss
Answer & Solution
Answer: Option C
Solution:
Sinkholes are depressions formed in soluble rock regions like limestone due to groundwater dissolution.Correct Answer: Sinkholes.
