Exam 7: Crustal Deformation and Mountain Building

Use the figure below to answer the following questions. -Which letter in the figure corresponds to a "fault"?

Any accreted crustal fragment that has a geologic history distinct from that of the adjoining fragments is termed an______ .

The_______ is are characterized by terrane accretion that has been active throughout most of Mesozoic and Cenozoic time.

Use the figure below to answer the following questions. -The concepts of "stress" and "strain" are related because_______ .

Based on your knowledge of isostasy, would you expect thicker or thinner crust beneath the Caribbean Islands e.g., near D than the continental region of Venezuela to the south?

The area labeled C shows an active fault bounding the range. Which best describes the motion on the fault?

What is the modern theory for orogenesis mountain building.?

The type of fold that has the two limbs at the same angle is called an_______ .

A region is characterized by numerous anticlines and synclines. There are also several faults present that appear to have formed at the same time as the folding. Without looking at any details, what type of faults would be most likely? Why?

Use the figure below to answer the following questions. -The material in the figure exhibited_______ behavior when the folding occurred.

The higher the temperature, the more likely it is that a _______rock will deform in a manner.

You are walking on the beach along the south- coast of Alaska. You see rocks cut by numerous faults that consist of basalt with evidence of eruption in the ocean, deep- water chert, mudstone, and sandstones with abundant volcanic material. What tectonic setting would you assign to these rocks?

The Himalayas and Tibet are the archetypical example of an_______ mountain belt.

The west coast of California is underlain by rocks that represent_______ .

Monoclines, anticlines, synclines and domes are all examples of_______ .

What type of structure is shown below?

Mountain building uplifts rocks against the force of gravity raising their potential energy, which requires work by the earth system. Based on the relative motion of fault blocks, what type of fault would you expect to require more energy than the others?

Use the figure below to answer the following questions. -In the figure, the stress on block 'X' is_______ .

What is the major difference between a subduction zone and a collisional mountain chain?

Folds are an example of _______.
