Read each question and all answer choices carefully, then choose the best answer.
This activity contains 26 questions.
Composition of the rock alone will determine how greatly the rock type influences the elastic limit and how the rock will deform.
True
False
Most crustal deformation occurs along plate margins.
True
False
When stress is gradually applied, rocks respond by flowing plastically.
True
False
Near the surface with low temperatures and confining pressures, brittle deformation
is less likely
is replaced by ductile deformation
never occurs
is more likely
always forms folds
Rock is more likely to fracture under stress near the surface because temperatures and confining pressure are low.
True
False
A ________ fault occurs when a hanging wall moves down relative to the footwall.
tensional
reverse
transform
normal
strike-slip
A fracture with horizontal displacement parallel to its surface trend is called a/an ____________ fault.
dip-slip
joint
strike-slip
overturned
oblique-slip
A thrust fault is a low-angle reverse fault.
True
False
Folding is usually the result of
shear forces
tensional forces
faulting
compressional forces
jointing
Faults where the movement is primarily vertical are called ____________ faults.
oblique
strike-slip
transform
random
dip-slip
Identify the type of fold illustrated by selecting the correct response.

This question presents 2 items numbered 11.1 through 11.2. Each item is presented with a pulldown menu containing the letters A through B.
For each item below, use the pull-down menu to select the letter that labels the correct part of the image.
11.1 Anticline
A
B
11.2 Syncline
A
B
Strike-slip faults that are associated with plate boundaries are called transform faults.
True
False
The most important difference between faults and joints is that joints
have no displacement
are very rare
are usually vertical
occur along folds
are often parallel
Trough-like structures produced from downfolded structures are often called
anticlines
synclines
batholiths
domes
none of the above
Complex orogenic forces that produce mountain belts often result in
faulting
igneous activity
folding
metamorphism
all of the above
The Appalachians formed as a result of orogenic activity
450-500 million years ago
400 million years ago
250-350 million years ago
b and c
all of the above
Most mountain building occurs in tensional environments.
True
False
The Andes Mountains include regions of
volcanic arcs
large intrusive bodies and high-temperature metamorphic rocks
folded and faulted sedimentary and metamorphic rocks
a and c
all of the above
Fault-block mountains are common in the Basin and Range Province of the southwestern United States.
True
False
Most major episodes of mountain building have occurred along divergent plate boundaries.
True
False
"Terrane" refers to any crustal fragment whose geologic history is distinct from that of adjoining fragments.
True
False
The Appalachians resulted from collisions between North America, Europe, and northern Africa.
True
False
The combined processes of ductile spreading at depth and normal faulting in the upper portion of the crust can result in the process of
compressional forces
gravitational collapse
terranes
isostasy
all of the above
Erosion of overlying layers can cause the underlying rocks to
rise
subside
subduct
thicken
fold
Isostatic adjustment occurs when there is addition or removal of weight from Earth's crust.
True
False
Over time, erosion and isostatic adjustment of older mountains will ___________ the crystalline mountain core.
bury
thicken
fold
melt
expose
