Question 1

A scientist observes rock masses that have moved past each other in opposite horizontal directions. Which feature does the scientist observe?

Revolt · Accepted Answer

strike-slip fault

Question 2

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

Revolt · Accepted Answer

shearing

Question 3

Which force created a fault-block mountain?

Revolt · Accepted Answer

tension

Question 4

Which best describes how wedge basins form?

Revolt · Accepted Answer

When two plates collide, the non-subducting plate scrapes the subducting plate and forms a depression where sediments gather.

Question 5

Where does shearing often occur?

Revolt · Accepted Answer

at a transform boundary

Question 6

A scientist observes a fault where the hanging wall has moved upward relative to the footwall. Which type of fault is the scientist observing?

Revolt · Accepted Answer

reverse

Question 7

The image shows a type of fault.

Revolt · Accepted Answer

compression

Question 8

Which type of basin forms at transform boundaries?

Revolt · Accepted Answer

strike-slip

Question 9

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

Revolt · Accepted Answer

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

Question 10
