Earthquakes

Normal faults occur when two plates

• come together

• pull apart

A type of fault where the hanging wall slides upward and the footwall moves downward

• normal fault

• reverse fault

• strike slip fault

A type of fault where the hanging wall slides downward is?

• normal fault

• reverse fault

• strike-slip fault

A type of fault where the rocks on either side of the fault slip past each other sideways, with little up or down motion is?

• normal fault

• reverse fault

• strike-slip fault

The stress force that pulls on the crust and thins rock in the middle is?

• shearing

• compression

• tension

• uplift

The stress force that squeezes rock until it folds or breaks is?

• shearing

• compression

• tension

• uplifting

Compression causes the formation of

• only anticlines

• only synclines

• both anticlines and synclines

• neither anticlines not synclines

The seismic waves that move the fastest are?

• P waves

• S waves

• surface waves

Seismic waves that can vibrate from side to side or up and down are?

• P waves

• S waves

• surface waves

Which of these scales rates earthquake damage at a particular location?

• focus

• Modified Mercalli

• Richter

• moment magnitude
