Forces in Earth's Crust

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.

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

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

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

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

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

strike-slip fault

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?

fault-block mountain
