Earthquakes Review

What type of stress pushes a mass of rock in 2 opposite directions?

• shearing

• tension

• compression

• deformation

In a normal fault, the part of the fault that lies below the fault line is called the

• hanging wall

• foot wall

• reverse fault

• anticline

What type of stress creates reverse faults?

• shearing

• tension

• compression

• deformation

The type of seismic wave that arrives first and moves by compressing and expanding the ground are called

• S waves

• P waves

• Surface waves

• Seismic waves

Compared to P and S waves, surface waves move

• slower

• faster

• at the same speed

• farther from the epicenter

What does a seismograph record?

• the Richter scale rathing for an earthquake

• the speed of seismic waves

• the seismic waves of an earthquake

• the location of the epicenter

Which of the following can cause damage days or months after a large earthquake?

• the arrival of surface waves

• liquefaction

• a tsunaim

• an aftershock

If the coast guard warns of a giant wave of water approaching the shore as a result of an earthquake, they are warning of

• an aftershock

• liquefaction

• a tsunami

• landslides

The best way to protect yourself in an earthquake is to

• run as fast as you can

• drop, cover, and hold

• go into the basement

• stand under a tree

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

• creep meter

• lasere-ranging device

• tiltmeter

• GPS satellite
