Exam 9: Folds, faults, and Geological Maps

Describe the differences between a topographic map and a geologic map.

The figure below shows a(n)_____ fault.

Uniform stress is stress that is stronger in one direction than in the other directions.

The compass orientation of a line of intersection between a horizontal plane and a planar feature such as a rock layer or a fault is known as the strike.

The San Andreas Fault is a_____ fault.

The diagram below shows the formation of a(n)_____ fault.

In the figure below,which part of the horst and graben structure is bound by normal faults,resulting in a down-dropping?

In the figure below,the dome structure is synonymous with a syncline.

An orogen is an area of continental crust that has remained undeformed for a very long time.

The Appalachian Mountains are a good example of anticlines and synclines.

Recognizable boundaries in rock layers are also known as _____.

According to the figure below,the sandstone unit is dipping NE at 46º.

Describe the difference between an anticline and a syncline.

The figure below illustrates what type of fault?

The presence of water enhances the ductile properties of rocks.

In the figure below,the axis of the syncline is dipping at _____ degrees.

An elongated region of the crust that has been deformed by continental collision is known as a(n)_____.

A shear is a stress that acts in a direction perpendicular to the surface.

In the figure below from the Old Red Sandstone,the syncline will have the oldest rocks in the middle.

Explain the difference between strike and dip.
