Below is a set of sample revision test questions along with detailed rationales designed to
help you prepare for ESS 101 B Examination 2: Introduction to Geology and Societal Impacts.
These questions cover key topics—from fundamental geological processes to the ways
geology affects society—and the provided rationale explains why each concept is important
and how it connects to broader course themes.
Revision Test Questions
1. Rock Types and the Rock Cycle
Question:
Which of the following correctly lists the three major rock types in the rock cycle?
A. Igneous, sedimentary, metamorphic
B. Igneous, volcanic, plutonic
C. Sedimentary, metamorphic, organic
D. Metamorphic, crystalline, sedimentary
Correct Answer: A
Rationale:
Understanding the rock cycle is fundamental in geology. This question ensures you can identify the three
main rock types—igneous (formed from cooled magma or lava), sedimentary (formed by the deposition
and cementation of material), and metamorphic (formed by the transformation of existing rock under
pressure and temperature). Recognizing these categories is crucial for later topics such as mineral
resource formation and geologic hazards.
2. Plate Tectonics and Earth Processes
Question:
What primary evidence supports the theory of plate tectonics?
A. Uniform distribution of earthquakes around the globe
B. Matching geological features across continents
C. The absence of seismic activity at mid-ocean ridges
D. Consistent mountain ranges across all continents
Correct Answer: B
Rationale:
Plate tectonics is a cornerstone of modern geology. The rationale behind this question is to highlight the
importance of matching geological features (e.g., similar rock types and fossil records found on different
continents) as evidence for continental drift and plate movement. This concept underpins
understanding of seismic activity, mountain building, and natural hazards.
3. Weathering and Erosion
, Question:
How do physical weathering and chemical weathering differ?
A. Physical weathering involves chemical reactions, whereas chemical weathering does not.
B. Physical weathering breaks rocks without altering their chemical composition; chemical weathering
changes the mineral structure.
C. Both types of weathering only occur in humid climates.
D. Chemical weathering is faster than physical weathering in all environments.
Correct Answer: B
Rationale:
This question reinforces the critical distinction between physical (mechanical) weathering—breaking
rocks into smaller pieces without changing their composition—and chemical weathering—altering the
minerals within the rock. Understanding these processes is important for topics such as soil formation,
landscape evolution, and even implications for construction and infrastructure.
4. Mineral Resources and Societal Impact
Question:
Which factor is most important when evaluating the sustainability of a mineral resource extraction
project?
A. The color and appearance of the mineral
B. The cost of extraction and potential environmental impacts
C. The political affiliation of local communities
D. The age of the mineral deposit
Correct Answer: B
Rationale:
This question connects geological resource studies with societal and environmental concerns. Evaluating
sustainability involves balancing the economic cost of extraction with potential negative impacts on the
environment and local communities. This topic is essential as it underpins discussions on environmental
ethics, resource management, and the broader implications of geology on society.
5. Geological Hazards
Question:
Which of the following is a primary reason why earthquakes occur?
A. The release of built-up stress along fault lines
B. The chemical decomposition of rocks in the crust
C. Rapid weathering of sedimentary rocks
D. Volcanic eruptions releasing magma into the atmosphere
Correct Answer: A
