Chapter 11 Mountain Building Practice Test

If a force is unable to deform rock at first, the rock may _______________ if the force is maintained over a long period of time.

A material that undergoes tensional stress tends to

• shorten.

• stretch.

• become distorted.

• become less dense.

In a typical fault-block mountain,

• thrust faulting plays an important part in its formation

• upwarping creates distinctive features known as domes

• compressional stresses are major forces

• large blocks of crust are uplifted along normal faults

Temperature and pressure affect brittle deformation and ductile deformation in which of the following ways?

• High temperature and low pressure favor brittle deformation, while low temperature and high pressure favor ductile deformation.

• High temperature and high pressure favor brittle deformation, while low temperature and low pressure favor ductile deformation.

• High temperature and low pressure favor ductile deformation, while low temperature and high pressure favor brittle deformation.

• High temperature and high pressure favor ductile deformation, while low temperature and low pressure favor brittle deformation.

Most joints occur in _______________ groups and are the result of large-scale regional stresses.

Faults are generally closely associated with

• monoclines.

• anticlines.

• synclines.

• symmetrical folds.

Which of the following would NOT be considered part of orogenesis?

• sedimentation

• folding

• thrust faulting

• igneous activity

Which of the following describes the movement of crust in a normal fault?

• Movement is mostly in a vertical direction.

• Movement is mostly in a horizontal direction.

• Movement occurs equally in a vertical and horizontal direction.

• Movement results in the shortening of crust.

Which of the following is a characteristic typical of folding in sedimentary rock layers?

• Upfolds are called synclines.

• Symmetrical folds are called monoclines.

• Downfolds are called synclines.

• Overturned folds have no trough.

Isostatic adjustment is affected by ice sheets in what way?

• By causing the Earth's crust to rise as ice melts

• By causing the Earth's crust to sink as ice accumulates

• By having no effect on the Earth's crust

• By causing the Earth's crust to become more stable
