A fault plane strikes north-south and dips steeply to the west.What type of fault is characterized by the rocks above the fault plane moving upward relative to the rocks below the fault plane?.If the sedimentary rocks on a geologic map form a zigzag pattern, the underlying structure probably consists of _.A broad circular or oval upward bulge of rock layers is called a(n) _.Downfolds or basins of layered rock are called:.Upfolds or arches of layered rock are called:.The ability of the rocks to resist deformation Which factor does not affect whether folding is severe or gentle.High temperatures and high confining pressures High temperatures and low confining pressures Low temperatures and high confining pressures Low temperatures and low confining pressures Which of the following conditions would favor folding rather than faulting?.Higher temperatures and higher confining pressures Higher temperatures and lower confining pressures Lower temperatures and higher confining pressures Lower temperatures and lower confining pressures If we wish our next sample of marble to deform plastically rather than as a brittle substance, we should conduct our next experiment at _. A sample of marble has deformed as a brittle substance during a laboratory experiment.How many angular measurements does it take to describe the orientation of fault surface?.What type of fault is characterized by the rocks above the fault plane moving downward relative to the rocks below the fault plane?.What types of faults are associated with shearing forces?.Which of the following is an example of a fault where the motion is primarily horizontal?.What types of tectonic forces cause faulting?.Two limbs dipping in the same direction - with one tilted beyond vertical An overturned fold is characterized by _.Young sediments are very brittle and not easily deformed Most igneous rocks are less deformable than most sedimentary rocksīasement rocks are more ductile than young sediments Most igneous rocks are more deformable than most sedimentary rocks Laboratory experiments indicate that _.Real rocks are not used in laboratory experiments as they are in nature The time of deformation is much shorter in laboratory experiments than in nature The pressures are much lower in laboratory experiments than in nature The temperatures are much lower in laboratory experiments than in nature The biggest difference between rock deformation experiments conducted in a laboratory and rock deformation that occurs naturally is that _.Rocks under low confining pressure are more likely to deform ductily than rocks under high confining pressure Most sedimentary rocks are more deformable than igneous rocks Hotter rocks are more likely to deform ductily than cooler rocks Which of the following statements about rock deformation is false?ĭeep crustal rocks are more likely to deform ductily than shallow crustal rocks.At transform plate boundaries one would expect to find _.At divergent plate boundaries one would expect to find _.At convergent plate boundaries one would expect to find _.The two sides of a fold are called its _.Which of the following is not a tectonic force responsible for folding or faulting rocks?.The angle at which a sedimentary bed is inclined from the horizontal is called the _.What type of forces dominate at convergent plate margins?.What type of forces dominate at divergent plate margins?.Which of the following types of tectonic forces tends to push two sides of a body in opposite directions so that they slide horizontally past one another?.If look at a vertical face of a cliff or a roadcut, you are seeing a _ view of the Earth.If you are flying in an airplane and you look down at the landscape, you are seeing a _ view of the Earth.ĭirection of intersection of the rock layer an a horizontal surfaceĪngle at which the bed inclines from the horizontal Multiple Choice Questions for Crustal Deformation - Chapter 15Įach chapter will include a few questions designed to test your knowledge of material covered in the chapter and in the Internet-based resources.
