Horst and graben terrane (fault block mountains), as seen in the Basin and Range Province of the western US, is dominated by this type of fault:
|
normal
|
|
Differential stresses that shorten a rock body are known as:
|
compressional stresses
|
|
If you examine a geologic map and find a fold in which the strike directions are all parallel, the dip angles are all 45 degrees, and the dip directions point toward the fold axis, that fold is:
|
non-plunging
|
|
Which of the following stresses would produce normal faulting?
|
tensional
|
|
Changes resulting from this type of deformation are permanent and not reversible.
|
plastic
|
|
Stress that elongates bodies by pulling them apart is:
|
tensional
|
|
The special type of compass used in geology to measure the strike and dip of a bed is:
|
brunton
|
|
In an anticline:
|
the limbs dip away from the axial plane and the oldest rocks are at the center
|
|
A ______________ is the angle that an inclined bed of rock slopes down into the ground. It is measured in a direction perpendicular to the strik
|
dip
|
|
If the hanging wall of a fault moves down, the fault would be classified as:
|
normal
|
|
Rocks that flow or bend under high temperatures and pressures are referred to as:
|
ductile
|
|
The San Andreas Fault is this type:
|
strike-slip
|
|
Which type of fault occurs at convergent plate boundaries?
|
reverse
|
|
A thrust fault is a type of high angle reverse fault.
|
false
|
|
For a fold in which the strike directions are all parallel, the dip angles are all 45 degrees, and the dip directions point toward the fold axis, the fold is a(an):
|
syncline
|
|
_____________ is the compass direction of the line that is produced by the intersection of an inclined layer of rock with an imaginary horizontal surface.
|
strike
