Fault Types
Hint
:
For
question 34
, a
ssume the sedimentary rocks beneath feature H have been folded into a convex-
upward structure that resembles an arch.
34. Is Feature H an anticline or syncline?
A. Anticline
B. Syncline
C. Hogback ridge
D. Both a syncline and anticline
Hint:
For
question 35
, use the geologic cross
-section of the Boulder area on this website to help you
determine the correct answer:
http://bcn.boulder.co.us/basin/watershed/geology/
. In particular, note
the landform associated with the outcropping of the Dakota Formation that is given on the cross
-
section.
35. What is Feature I (linear feat
ure) which is located at the base of the Rocky Mountains?
A. Anticline
B. Syncline
C. Hogback ridge
D. Both a syncline and anticline
Hint:
For
question 36
, note that the feature in question may not be as high as a cliff; it may simply be a
short but no
ticeable vertical face that results in a “step” in the landscape
(see Section 11.10 in the
textbook for an example).
36. What is the name of the cliff face formed by a normal fault?
A. Scarp
B. Talus
C. Scree
D. Slide
37. What is Feature
J? (Click the downward pointing cones to determine which feature is J and which
is K).
A. Horst
B. Graben
C. Ridge
D. Reverse fault
38. What is Feature K?
A. Horst
B. Graben
C. Ridge
D. Reverse fault
39. What fault is not associated with uplift?
A. Normal
B. Reverse
C. Overthrust
D. Strike-slip
40. Are faults limited to land, or can they occur under water as well? Explain why or why not.
A. Limited to land, as there is no evidence of faulting under water
B. Limited to land, as faulting is a continental crust phenomen
on
C. Not limited to land, as faulting can occur under water
D. Not limited to land, as faulting requires at least one side to be oceanic.
Explanation / Answer
Answer
(1). (D) African plates- having two number of plates
(2). (D) Extinct volcano - Because in mesozoic era Pangea begun to breakup.
(3). (D) East Africa - East Africa may be the site of the Earth's next major ocean. Because here plate diverge and rifting.
(4). (C) Ferile soil - physical breakdown and chemical weathering of volcanic rocks have formed some of the most fertile soils on Earth.
(5). (A) Facific and north american plate - It forms the tectonic boundary between the Pacific Plate and the North American Plate.
