2026 QUESTIONS AND ANSWERS | A+
GRADED | WITH EXPERT SOLUTIONS
Deformation - correct answer-Refers to all changes in the size,
shape, or position of a rock body in response to stress.
Confining pressure - correct answer-equal in all directions,
associated with the weight of the overlaying rocks.
Differential stress - correct answer-not equal in all directions,
associated with tectonic activity.
can any rock deform in a brittle or ductile manner? - correct
answer-Any rock can deform in a brittle or ductile manner,
depending on the conditions of the deformation.
What are the main factors that affect rock deformation? - correct
answer-Temperature, confining pressure, Time (strain rate)
, Page | 2
Anticlines - correct answer-are upfolded or arched rock layers.
Synclines - correct answer-are downfolded or tough-like rick
layers.
Domes - correct answer-are upward circular or oval structures.
Basins - correct answer-are downwarped circular or oval
structures.
Fault - correct answer-Are fractures along which displacement
has occurred.
Normal fault - correct answer-the hanging wall moves down
relative to the footwall.
, Page | 3
Reverse fault - correct answer-hanging wall moves up relative to
the footwall.
Thrust faults - correct answer-reverse faults that have dip angles
less than 45 degrees.
Strike-slip faults - correct answer-displacement is horizontal,
parallel to the strike of the fault.
In general, most of Earth's mountain belts have been produced by
what? - correct answer-by tectonic plate activity. Subduction
zones, Continential collision zones, and divergent margins.
Island arc-type mountain building - correct answer-Mountainous
volcanic chain of islands & volcanic growth triggered by partial
melting in the mantle wedge above the subjected zone.
Andean-type mountain building - correct answer-Subduction
beneath a continent, long lasting igneous activity, & volcanic
mountain growth is triggered by partial melting in the mantle
wedge and lower congenital crust. Ex: Andes Mountains
