Environmental Science A/B Forces in Earth's Crust

What type of fault occurs when plates move past each other in opposite directions?

Strike-slip fault

Which type of fault occurs when rock is subjected to this type of stress?

normal

A scientist observes a feature where the hanging wall moved downward relative to the footwall. Which feature does the scientist observe?

normal fault

Use the drop-down menus to label the landforms in the image.

A: anticline B: syncline

Use the drop-down menus to correctly identify the type of fault in each diagram.

A: normal B: reserve C: strike-slip

Which type of basin forms at transform boundaries?

strike-slip

Where does shearing often occur?

at a transform boundary

What type of stress occurs when one plate pushes against another?

compression

Which force created a fault-block mountain?

tension

Which type of stress causes fault-block mountains?

tension

How is a plateau different from a fault-block mountain?

A plateau forms when a flat block of rock is uplifted, and a fault-block mountain does not.

What type of plate boundary is illustrated in the image What is the movement of one plate below another called?

Convergent subduction

Use the drop-down menus to correctly identify the type of stress associated with each type of plate boundary. Divergent plate boundary: Transform plate boundary: Convergent plate boundary:

Divergent plate boundary: tension Transform plate boundary: shearing Convergent plate boundary: compression

Use the drop-down menus to answer the following questions about the diagram. Label the parts of the diagram using the drop-down menus. What is featured at label A? What is featured at label B? What type of fault is featured in this diagram

Footwall Hanging wall Normal Fault

A geologist discovers a fault in a massive rock while out in the field. He notices that the fault occurs at an angle and that the hanging wall has moved downward from the footwall. What type of fault has the geologist found?

Normal fault

The San Andreas Fault is the boundary between two of Earth's tectonic plates: the Pacific Plate and the North American Plate. This boundary is a transform boundary. The Pacific Plate is moving to the north and west, while the North American Plate is moving to the south and east. What type of stress is most likely to occur at this boundary?

Shearing

Which statements describe reverse faults? Check all that apply.

The hanging wall moves up. The fault is at an angle. The fault is caused by compression. The plates are colliding

Answer the questions using the drop-down menus. At what type of boundary do strike-strip basins form? At what type of boundary do wedge basins form? At what type of boundary do rift basins form? At what type of boundary do arc basins form?

Transform Convergent Divergent Convergent

A geologist sees this folded rock when studying in the field. He is drawn to the sample that is labeled A. He determines this formation was caused by compression. What type of landform did he find at label A?

anticline

Which feature is most likely found at a divergent boundary?

fault- block mountain

A geologist is making observations from atop a small mountain. She sees two parallel faults: one directly to the east and one directly to the west. She concludes that these faults are caused by tension stretching the crust. From what type of land feature is the geologist making her observations? plateau

fault-block mountain

What type of stress occurs when a rock mass is pushed in parallel and opposite directions?

shearing
