Faults and Rifts

A type of fault where rocks on either side move past each other sideways is called:

• normal fault
• reverse fault
• strike-slip fault

A type of fault where rocks on either side move past each other sideways is called:

• normal fault
• reverse fault
• strike-slip fault

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.

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.

The composition of Earth's interior affects

• how long an earthquake will last
• the speed and direction of seismic waves
• the location of an earthquake's focus
• the strength of an earthquake

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

• tension
• compression
• shearing

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

• normal
• reverse

What fault has little up or down motion?
