DOUBLE JEOPARDY
Name the three types of stress that cause deformation in earth's crust and how they move.
What is tension where the rocks stretch apart, compression where the rocks push together, and shearing where the rocks move sideways in opposite directions?
300
This scale describes the effects of an earthquake on people, buildings, and land at a given location.
What is the Mercalli's scale?
300
Most earthquake-related deaths and injuries result from this.
What is damage to building or other structures?
300
What base-isolated buildings are designed to do to the amount of energy released by an earthquake.
What is decrease the amount of energy?
300
The point on Earth's surface directly above an earthquake's focus.
What is the epicenter?

After locating the distance from the epicenter of three cities, this is the next step.
What is draw a circle to scale on a map to show where the city's distance is from the epicenter and see where all three intersect?
400
This type of building absorbs the energy of seismic waves.
What is a base-isolated building?

DOUBLE JEOPARDY - Compare and contrast the faults made by tension and compression.
What is tension is where the rock moves apart and the hanging wall goes up and the footwall goes down, compression is where rock gets squeezed together and the hanging wall goes down and the footwall goes up.

What is they cannot be sure when and where the stress will be released along a fault?
500
Name two ways that buildings can be built to reduce the affects of an earthquake.
What is build reinforcements to buildings and allow buildings to sway during an earthquake?
500
Risk of an earthquake is based on these two factors.
What is where faults are active and where past earthquakes occurred?
