Earthquakes

Fault block mountains are created when a string of what occurs?

• normal faults
• reverse faults
• strike-slip faults
• folds

A device that uses wire stretched across a fault to measure horizontal movement of the ground is called a 

• tilt meter
• creep meter
• laser ranging device
• GPS satellites

Which stress force pulls on the crust and stretches rock?

• tension
• compression
• shearing
• folding

Which of the following monitors ONLY vertical movements (rising and falling) along a fault?

• tiltmeter
• creep meter
• laser ranging device
• GPS satellite

The rating system that estimates the total energy released by an earthquake is called the

• Richter scale
• moment magnitude scale
• Mercalli scale
• modified Mercalli scale

What process occurs when an earthquake's shaking turns loose soil into mud?

• aftershocks
• tsunamis
• liquefaction
• deformation

What type of deformation is this rock displaying?

• folds
• ductile
• liquefaction
• brittle

Stress that pushes a mass of rock in two opposite directions is called

• deformation
• tension
• compression
• shearing

The best way to protect yourself in an earthquake is to 

• run as fast as you can
• drop, cover and hold
• stop, drop and roll
• go into the basement

The type of seismic waves that arrive at a seismic station first and move by compressing and expanding the ground like an accordian are called

• S waves
• surface waves
• tsunami waves
• primary waves
