100
This is the movement and shaking resulting from the movement of rock beneath the crust.
What is an earthquake?
100
This force opposes the motion of another surface as it moves across it.
What is friction?
100
This is the point beneath the surface where rocks break under stress and form an earthquake.
What is the focus?
100
This is generated by an earthquake wave when water becomes displaced.
What is a tsunami?

FINAL JEOPARDY ANSWER: This American seismologist developed a scale in the 1930's to measure earthquakes. This scale works well for small nearby earthquakes, but not so well for larger distant ones. You must give me the FIRST AND LAST NAME.
Who is Charles Richter?
200
It's not what you feel before a test, but it's a force acting on a rock to change its shape or volume.
What is stress?
200
This fault is created by shearing stress, and San Andreas is one example of it.
What is the strike-slip fault?
200
This rock fold bends upward into an arch.
What is an anticline?
200
This takes place after a larger earthquake in as little as a few hours or as much as aseveral days.
What is an aftershock?
200
This tool measures the intensity of an earthquake by recording ground movements caused by seismic waves.
What is a seismograph?
300
This type of something pushes rock into two opposite directions. Think of tearing up a piece of paper.
What is shearing stress?
300
in two of the three fault types, this is the block of rock which moves above or below the other side of the fault.
What is the hanging wall?
300
This is the most destructive of the three types of seismic waves.
What is the surface wave?
300
This process turns loos soft soil into liquid mud.
What is liquefaction?
300
These measure the image of faults before and after an earthquake strikes.
What is a satellite monitor?
400
This term describes when the crust bends, folds, tilts or slides as a result of plates shifting.
What is deformation?
400
This fault is created by compression stress, with Glacier National Park, MT, as a great example.
What is a reverse fault?
400
These mountains are formed by uplifting of rock blocks in a normal fault. The GReat Basin in UT and NV is an example.
What is a fault-block mountain?
400
This is the process to protect yourself in the event of an earthquake.
What is drop, cover and hold?
400
This device measures the tilting of the ground.
What is a tiltmeter?
500
It's a type of headache, or what happens when a rubber band is stretched.
What is tension stress?
500
This block of rock is the portion of the fault which does NOT change its position in an earthquake.
What is the foot wall?
500
This scale describes the effects on people, buildings and the land surfaces in twelve easy steps, and is no longer in use.
What is the Mercalli scale?
500
This type of building rests upon shock-absorbing pads or springs.
What is base-isolated?
500
This device measures the horizontal movement of land masses and faults.
What is a creep meter?
