QUESTIONS AND CORRECT ANSWERS
Question:
1. (Ch. 9) Explain the difference between deformed and undeformed rock.
A. Undeformed rocks contain geologic structures, whereas deformed rocks do not.
B. Orogenies create undeformed rocks with geologic structures, and deformed rocks form through
sedimentary processes.
C. Deformed rocks generally form near passive tectonic margins, whereas undeformed rocks are affected
by tectonic stress.
D. Deformed rocks are bent, broken, or flowed in response to stress, whereas undeformed rocks are
unaltered.
Answer:
D. Deformed rocks are bent, broken, or flowed in response to stress, whereas undeformed rocks are
unaltered.
Question:
2. The rock shown in the image below is an example of ________ rock.
Answer:
deformed
Question:
3. During _______ deformation rocks visibly break, whereas during ________ deformation they change
shape without breaking.
Answer:
brittle, plastic
,Question:
4. What factors determine which type of deformation takes place? (Select all that apply)
1. weather
2. age
3. pressure
4. composition
5. deformation rate
6. temperature
Answer:
3, 4, 5, 6
Question:
5. During deformation, the amount of force applied to a rock is called _________ , whereas the change in
the shape of a rock is called __________.
Answer:
stress, strain
Question:
6. The image below shows two fossil shells. The top one is undeformed, and the bottom one is the same
type of shell, after deformation. What kind of strain does the deformed example display in the east-west
direction?
A. shearing
B. shortening
C. stretching
Answer:
B. shortening
Question:
7. What is the difference between a joint and a vein?
Answer:
A joint is a crack that develops in rocks due to tension. Veins are minerals that fill the space in a rock
crack.
