31
Which property of rocks is most critical in designing foundations for dams?
Discuss
Answer & Solution
Answer: Option A
Solution:
Compressive strength is the measure of a rock's ability to withstand loads without failure.This property is essential for dam foundations, which must support enormous structural loads and resist water pressure.Correct Answer: Compressive strength.
32
What does the term 'weathering' refer to in geology?
Discuss
Answer & Solution
Answer: Option D
Solution:
Weathering is the physical, chemical, or biological breakdown of rocks at or near the Earth's surface.It happens in situ, meaning there is no movement of the rock material.Correct Answer: Breaking down of rocks in place.
33
Which mineral is the hardest on the Mohs scale?
Discuss
Answer & Solution
Answer: Option C
Solution:
Diamond ranks 10 on the Mohs hardness scale, making it the hardest known natural material.Correct Answer: Diamond.
34
What is the purpose of geological borehole logging?
Discuss
Answer & Solution
Answer: Option B
Solution:
Borehole logging involves collecting detailed records from boreholes to analyze subsurface formations.This helps in geological mapping and design decisions.Correct Answer: Determine subsurface conditions.
35
Which geological structure is represented by a fold that arches upward?
Discuss
Answer & Solution
Answer: Option C
Solution:
Anticline is an upward-arching fold with the oldest rock layers at the core.It contrasts with a syncline, which dips downward.Correct Answer: Anticline.
36
Which type of rock is formed from cooled magma?
Discuss
Answer & Solution
Answer: Option D
Solution:
Igneous rocks are formed through the cooling and solidification of molten rock, either magma or lava.Correct Answer: Igneous.
37
What is the main concern when tunneling through fault zones?
Discuss
Answer & Solution
Answer: Option A
Solution:
Fault zones are fractured and weak, increasing risks of instability and groundwater ingress during tunneling.Correct Answer: Water seepage and instability.
38
Which tool is used to measure the orientation of geological features?
Discuss
Answer & Solution
Answer: Option D
Solution:
A compass clinometer is used to measure the strike (horizontal angle) and dip (inclination) of rock layers.Correct Answer: Compass clinometer.
39
What is an unconformity in geology?
Discuss
Answer & Solution
Answer: Option C
Solution:
An unconformity is a surface that represents a break or gap in the geological record due to erosion or non-deposition.Correct Answer: A gap in the geological record.
40
Which rock property is tested using the slake durability test?
Discuss
Answer & Solution
Answer: Option B
Solution:
The slake durability test evaluates a rock's resistance to weakening and disintegration through wet-dry cycles.Correct Answer: Durability under wetting and drying.
