Earthquake Faults

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

When the hanging wall slips downward below the footwall, what kind of fault is it?

• strike-slip
• normal
• reverse

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

• True 
• False

Which of these boundaries/stresses/faults all correctly go together?  Choose all that apply.

• normal, divergent, tension
• reverse, convergent, shearing
• strike-slip, transform, compression

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

• compression
• combining

Rock layers undergo stress when they are stretched apart at divergent boundaries. This stress is called:

• tightening
• tension

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

• fracture
• fault
• joint
