71
What is the Mohs hardness of Quartz?
Discuss
Answer & Solution
Answer: Option C
Solution:
Quartz ranks 7 on the Mohs hardness scale, meaning it can scratch materials with lower hardness.Correct Answer: 7.
72
What does a topographic map primarily represent?
Discuss
Answer & Solution
Answer: Option C
Solution:
A topographic map uses contour lines to show changes in elevation and landform shapes, which is essential for planning infrastructure.Correct Answer: Elevation changes.
73
Which of the following formations is typically the best aquifer?
Discuss
Answer & Solution
Answer: Option C
Solution:
Sandstone is often porous and permeable, allowing it to store and transmit groundwater efficiently.Correct Answer: Sandstone.
74
What does geotechnical investigation typically assess before construction?
Discuss
Answer & Solution
Answer: Option C
Solution:
Geotechnical investigations analyze soil and rock conditions to determine their strength, stability, and suitability for construction.Correct Answer: Subsurface soil and rock properties.
75
In geological mapping, what are contour lines used for?
Discuss
Answer & Solution
Answer: Option C
Solution:
Contour lines connect points of equal elevation on a map and help visualize landforms and slope gradients.Correct Answer: Representing equal elevation.
76
Which of the following is a foliated metamorphic rock?
Discuss
Answer & Solution
Answer: Option B
Solution:
Schist is a foliated metamorphic rock characterized by visible layers or bands caused by high pressure and temperature conditions.Foliation results from the alignment of platy minerals like mica.Correct Answer: Schist.
77
Which factor directly affects the bearing capacity of soil?
Discuss
Answer & Solution
Answer: Option A
Solution:
Soil texture determines particle size distribution and compaction characteristics, which affect the soil's ability to bear structural loads.Correct Answer: Soil texture.
78
Which process involves movement of weathered material?
Discuss
Answer & Solution
Answer: Option B
Solution:
Erosion is the transportation of weathered material by agents like water, wind, or ice.It differs from weathering, which is the breakdown of rocks in place.Correct Answer: Erosion.
79
Which technique is used to map subsurface layers without excavation?
Discuss
Answer & Solution
Answer: Option A
Solution:
A seismic survey uses the propagation of seismic waves to map subsurface geological structures.It is commonly used in site investigations and oil exploration. Correct Answer: Seismic survey.
80
What is the typical structure of sedimentary rocks?
Discuss
Answer & Solution
Answer: Option A
Solution:
Sedimentary rocks are often layered or bedded due to the deposition of material in successive horizontal strata.Correct Answer: Layered.
