Over long periods of time, tectonic forces can cause rocks to fold. What kind of stress causes folding?

• tension

• shear stress

• compression

• normal stress

Imagine that you are a geologist looking at two different folds. You observe that in the first fold, the rocks get younger the farther they are away from the center of the fold. In the second fold you observe that the rocks get older the farther they are away from the center of the fold. Which of the following correctly

describes what you observe?

• The first fold is a syncline and the second fold is an anticline.

• The first fold is an anticline and the second fold is a syncline.

• The first fold is a syncline and the second fold is a monocline.

• The first fold is an anticline and the second fold is a monocline.

Long ago the eastern part of North America collided with the northern part of Africa during the formation of the supercontinent Pangaea. Later, the two continents separated as Pangaea broke apart. Which of the following describes what happened when the two continents collided?

• Folded mountains formed as a result of tensional stress.

• Fault-block mountains formed as a result of tensional stress.

• Folded mountains formed as a result of compressional stress.

• Fault-block mountains formed as a result of compressional stress.

Tectonic plates can move toward each other and squeeze large blocks of rocks together, creating folded mountains. Which of the following terms describes a kind of fold in which the oldest rock layers are in the center of the fold?

• syncline

• anticline

• symmetrical fold

• asymmetrical fold

What is the primary way that folded mountains are formed?

• by tension

• by shear stress

• by compression

• by volcanic activity

The San Andreas Fault in California is a strike-slip fault. Which of these statements best describes a strike-slip fault?

• Two fault blocks move in the same direction.

• One fault block moves up relative to the other.

• One fault block moves down relative to the other.

• Two fault blocks move past each other horizontally.
