2026 Q&A | Instant Download Pdf
(Covers: Engineering Geology, Hydrogeology, Geomorphology, Geotechnical
Engineering, Structural Geology, Seismology, and Field Methods)
1. The primary purpose of an engineering geologist is to:
A. Design building foundations
B. Evaluate geological factors that may affect engineering works
C. Draft construction blueprints
D. Perform environmental impact assessments
Rationale: Engineering geologists assess geological conditions to ensure
engineering structures are built safely and efficiently.
2. Which rock type is most likely to develop karst topography?
A. Sandstone
,B. Shale
C. Limestone
D. Basalt
Rationale: Limestone dissolves in slightly acidic water, forming sinkholes,
caves, and other karst features.
3. The main control on slope stability is:
A. Climate
B. Vegetation
C. Shear strength of materials and slope angle
D. Seismic activity
Rationale: Slope stability depends on the balance between driving forces
(weight) and resisting forces (shear strength).
4. Which geophysical method is most useful for detecting subsurface
cavities?
A. Seismic refraction
B. Ground-penetrating radar (GPR)
C. Resistivity sounding
D. Gravity survey
Rationale: GPR provides high-resolution imaging for detecting voids or
cavities in near-surface materials.
,5. Which soil classification system is primarily used for engineering purposes
in the United States?
A. USDA
B. Unified Soil Classification System (USCS)
C. AASHTO
D. ASTM
Rationale: The USCS is the standard engineering soil classification system
used for design and construction.
6. The term “angle of repose” refers to:
A. The slope angle of a cut made in rock
B. The maximum slope angle at which loose material remains stable
C. The natural dip of bedding planes
D. The inclination of a fault plane
Rationale: Angle of repose is the steepest angle at which granular material
remains stable without sliding.
7. Which type of fault has the hanging wall moving downward relative to the
footwall?
A. Normal fault
B. Reverse fault
, C. Strike-slip fault
D. Thrust fault
Rationale: In normal faults, tensional stress causes the hanging wall to
move downward relative to the footwall.
8. Liquefaction most likely occurs in:
A. Solid bedrock
B. Dry sandy soils
C. Saturated, loose sandy soils during seismic shaking
D. Clay-rich soils
Rationale: Loose, saturated sands lose strength under vibration, causing
liquefaction.
9. The seismic S-wave is characterized by:
A. Being the fastest seismic wave
B. Moving perpendicular to the direction of wave propagation
C. Traveling through both solids and liquids
D. Having the smallest amplitude
Rationale: S-waves move material perpendicular to the wave direction and
only travel through solids.
