LSU GEOL 1001 Exam 2 Practice Questions
(Verified Update!!!!!)
Instructions: This exam consists of multiple-choice questions.
Choose the best answer for each question. The questions are
organized by major topic areas based on the GEOL 1001
curriculum.
Section 1: The Rock Cycle & Surface Processes (Questions)
1. What is the rock cycle?
A) A process that describes the transformation of rocks
between igneous, sedimentary, and metamorphic types
through geological processes
B) A type of bicycle used by geologists
C) A method of dating rocks
D) A type of rock formation
Answer: A
Rationale: The rock cycle describes the continuous
transformation of rocks between igneous, sedimentary, and
metamorphic types through geological processes.
2. What drives the rock cycle?
A) Plate tectonics and the hydrologic cycle
, Page |2
B) Only solar energy
C) Only gravity
D) Only radioactive decay
Answer: A
Rationale: The rock cycle is driven by plate tectonics (internal
heat) and the hydrologic cycle (external solar energy).
3. What is the fundamental difference between the three rock
types?
A) How they form
B) Their color
C) Their hardness
D) Their age
Answer: A
Rationale: The three rock types (igneous, sedimentary,
metamorphic) are distinguished by how they form.
4. Can any rock type be transformed into any other rock type?
A) Yes, through the rock cycle
B) No, only igneous rocks can change
C) No, only sedimentary rocks can change
D) No, rocks are permanent
Answer: A
Rationale: Through the rock cycle, any rock type can be
transformed into any other rock type.

5. What is the first step in the formation of a sedimentary
rock?
A) Weathering of pre-existing rock
B) Melting of rock
C) Metamorphism of rock
D) Crystallization of magma
Answer: A
Rationale: Weathering of pre-existing rock is the first step in
forming a sedimentary rock.
6. What is weathering?
A) The in-situ alteration of rocks at or near the surface
B) The transport of rock fragments
C) The melting of rock
D) The solidification of magma
Answer: A
Rationale: Weathering is the in-situ (in place) alteration of rocks
at or near the Earth's surface.
7. What is the difference between weathering and erosion?
A) Weathering breaks down rock in place; erosion transports
the weathered material
B) Erosion breaks down rock; weathering transports material
C) They are the same
D) Weathering only occurs in water
, Page |4
Answer: A
Rationale: Weathering is the breakdown of rock in place, while
erosion is the transportation of weathered material.
8. What is mass wasting?
A) The downslope movement of rock and soil under the
influence of gravity
B) The breakdown of rock by chemical processes
C) The transport of sediment by streams
D) The formation of soil
Answer: A
Rationale: Mass wasting is the downslope movement of rock
and soil under the influence of gravity.
9. What is the combined effect of weathering, mass
movement, and erosion on the Earth's surface?
A) They break down and transport material, shaping the
landscape
B) They build mountains
C) They have no effect on the landscape
D) They only affect rocks underground
Answer: A
Rationale: Weathering, mass movement, and erosion work
together to break down and transport material, shaping the
Earth's surface.
