California Certified Engineering Geologist Examination
1. Which engineering geologic investigation objective is considered the
most fundamental when evaluating a proposed building site located
within an area containing known geologic hazards?
A. Identifying aesthetic landscape features for future development
planning
B. Determining potential geologic conditions that could threaten
public safety, property, or infrastructure performance
C. Selecting vegetation appropriate for long-term landscaping
requirements
,D. Estimating future property tax values based upon nearby
development
Answer: B
Rationale: Engineering geology primarily evaluates geologic hazards
affecting structural safety and long-term site performance.
2. During an engineering geologic field investigation, which
observation provides the strongest evidence that a rock mass may
possess reduced engineering strength because of structural
discontinuities?
A. Bright mineral coloration across exposed surfaces
B. Numerous closely spaced fractures exhibiting weathering,
alteration, and groundwater seepage
C. Presence of sparse vegetation on nearby slopes
D. Uniform bedding thickness throughout the exposure
Answer: B
Rationale: Weathered fractures and seepage significantly reduce rock
mass strength and stability.
3. Which description best characterizes the primary engineering
significance of discontinuities such as joints, faults, and bedding planes
within rock masses evaluated for construction projects?
A. They generally increase rock strength by improving drainage.
B. They commonly control failure surfaces, groundwater movement,
and excavation stability.
, C. They eliminate settlement concerns beneath foundations.
D. They prevent weathering from affecting engineering properties.
Answer: B
Rationale: Discontinuities strongly influence slope failures, seepage,
excavation behavior, and foundation performance.
4. Why is detailed geologic mapping considered an essential component
of nearly every engineering geologic investigation performed before
significant construction activities begin?
A. It replaces all laboratory testing requirements.
B. It identifies geologic materials, structures, hazards, and
engineering conditions influencing project design.
C. It determines future property ownership boundaries.
D. It eliminates the need for subsurface exploration.
Answer: B
Rationale: Geologic mapping provides the framework for
understanding engineering conditions and planning investigations.
5. Which field characteristic most strongly suggests that a slope has
experienced previous landslide activity requiring additional engineering
evaluation before development proceeds?
A. Uniform grass cover without visible disturbances
B. Head scarps, hummocky topography, tilted trees, and disrupted
drainage patterns
C. Horizontal sedimentary bedding exposed continuously
