Exam 7: Crags, Cracks, and Crumples: Crustal Deformation and Mountain Building

The outer portion of a craton, where deformed rocks are covered by sediments, is termed the

Compare and contrast domes and basins. If both are composed solely of sedimentary beds that have been eroded such that the ground surface is level, how would you identify each?

Regions of continents that have NOT been subjected to mountain-building events during the past 1 billion years are termed

The distinction between joints and faults is that

The fossil in the image below has been subjected to what type of stress?

Folds are most often associated with _________ stress.

What are the three components of deformation? Briefly explain each.

Which of the following is the process whereby rocks from depth are exposed at the surface during mountain building?

How were the mountains in the Basin and Range Province formed?

What are joints? What might the presence of joints in a rock indicate?

Erosional processes work to remove material from mountains; thus, over time the topography will become less

A body of rock affected by tension will likely undergo

Metamorphic rocks found in cratons are exposed during orogenesis by

Tectonic foliation is most likely to occur as a result of

What types of geologic structures would you expect to find in an area that had undergone compression?

Describe the differences between brittle and ductile deformation.

Normal faults are generally the result of _________ stress.

How does the rate at which a body of rock is deformed affect its behavior?

What do strike and dip describe?

The Appalachian Mountains were formed as a result of the collision of North America and Africa at the end of the Paleozoic era. Describe what the Appalachians looked like when formed and what has caused them to become a series of gently sloping hills today.
