Topic 4 Lesson 3 test

Stretching rock so it becomes thinner in the middle is what kind of stress?

• tension
• compression
• shearing

Squeezing rock until it breaks is what stress?

• tension
• compression
• shearing

The hanging wall slides up and over the footwall is what kind of fault?

• strike-slip
• normal
• reverse

What fault has little up or down motion?

• strike-slip
• normal
• reverse

Compression is the type of stress that causes the crust to become thinner in the middle.

• True 
• False

Rock layers undergo stress when they are squeezed at convergent boundaries. This stress is called:

• compression
• combining

The surface along which rock break and slide past each other is called a:

• fracture
• fault
• joint

How does a reverse fault form?

• The hanging wall moves upward relative to the footwall.
• Compression thrusts the fault into reverse.
• Blocks slide past each other.
• The hanging wall moves downward relative to the footwall.

A fold that results in an arch shape is a syncline.

• True

• False

When the crust is stretched by rock moving in opposite directions, compression occurs.

• True

• False
