Discuss rock deformation and list the factors that influence the strength of a rock.

This activity contains 10 questions.

	Which one of the following is not a form of rock deformation?   elastic deformation fracturing erosion ductile deformation none of the above

	As heat and pressure increase, ductile deformation   becomes more likely is replaced by elastic deformation becomes less likely can cause erosion stops occurring

	Under surface conditions, rocks that exceed their elastic limit behave like a brittle solid and fracture.    True  False

	What determines the general strength of a rock?   temperature confining pressure rock type time a and c all of the above

	If rocks return to their original shape when stress is removed, we call this __________ deformation.   ductile brittle compressional plastic elastic

	Which of the following rocks is most likely to behave in ductile manner?   granite quartzite rock salt basalt none of the above

	Older granitic rocks in the continental shield will never deform.    True  False

	The answer choices represent a hypothetical sequence of events during rock deformation experiments. The events are given from start (left) to finish (right) and separated by a semicolon (;). Which of the following sequences is most likely based on actual rock deformation experiments?   initial stress applied; elastic limit exceeded; elastic deformation elastic limit exceeded; initial stress applied; ductile deformation initial stress applied; elastic limit exceeded; ductile deformation initial stress applied; brittle deformation; elastic limit exceeded none of the above is possible

	Brittle deformation is a type of solid-state flow.    True  False

	Crystalline rocks with strong internal molecular bonds are more likely to experience failure by   elastic deformation brittle fracture plastic flow ductile deformation none of the above
