51
Which rock structure can act as a conduit for groundwater movement?
Discuss
Answer & Solution
Answer: Option A
Solution:
Faults create fractured zones in rock which may allow groundwater to flow easily through them.Correct Answer: Fault.
52
Which factor most influences soil erosion on slopes?
Discuss
Answer & Solution
Answer: Option A
Solution:
Slope angle affects the speed of water runoff and gravitational pull on the soil, increasing erosion risk on steeper slopes.Correct Answer: Slope angle.
53
What is the term for the vertical difference between the highest and lowest points in an area?
Discuss
Answer & Solution
Answer: Option C
Solution:
Relief is the difference in elevation between the highest and lowest points in a landscape.Correct Answer: Relief.
54
Which test is used to determine the permeability of soil in the field?
Discuss
Answer & Solution
Answer: Option A
Solution:
The falling head test measures the permeability of fine-grained soils by observing the rate of water drop in a standpipe.Correct Answer: Falling head test.
55
What is the role of geological engineering in construction projects?
Discuss
Answer & Solution
Answer: Option C
Solution:
Geological engineers assess the behavior of rocks and soils to ensure safe, stable, and efficient construction designs.Correct Answer: Assessing earth material behavior.
56
What is the geological term for the zone of weathered rock and soil above the water table?
Discuss
Answer & Solution
Answer: Option B
Solution:
The vadose zone is the unsaturated zone above the groundwater table where pores contain both air and water.Correct Answer: Vadose zone.
57
Which factor is least important in rock mass classification systems like RMR or Q-system?
Discuss
Answer & Solution
Answer: Option B
Solution:
Rock color is a visual property but has little impact on mechanical behavior. Key classification systems use structural and mechanical properties.Correct Answer: Rock color.
58
Which device is used for determining groundwater table in boreholes?
Discuss
Answer & Solution
Answer: Option B
Solution:
A piezometer is a device that measures the pressure head of groundwater, helping to determine the water table level.Correct Answer: Piezometer.
59
Which rock is typically most susceptible to chemical weathering?
Discuss
Answer & Solution
Answer: Option C
Solution:
Limestone is highly reactive with acidic solutions due to its calcite content, making it vulnerable to dissolution.Correct Answer: Limestone.
60
What is the main engineering concern in karst terrain?
Discuss
Answer & Solution
Answer: Option C
Solution:
Sinkholes form in karst terrain where groundwater dissolves soluble rocks like limestone, posing hazards for construction.Correct Answer: Presence of sinkholes.
