If you are stuck inside during an earthquake, 

name 1 thing you should do and 1 thing you should not do.

Answers may vary:  

Do:  hide under a table

Don't:  try to get out of the building  during the shaking

200
What is a divergent boundary?
The space between 2 tectonic plates that are moving away from each other
200
What type of stress did we demonstrate with a rubber band?
tension stress
200
In order to make an accurate estimation, a seismologist should study data from at least ____ different seismic stations to locate the epicenter of an EQ
3
200
State the order of seismic waves from first to last
P-wave,  S-wave,  Surface wave
300
Name the 4 after-effects of earthquakes
Fire, building collapse, landslides/mudslides, and tsunami
300
What is the term used for a geologist that studies earthquakes?
Seismologist
300
Any force exerted on the matter of an object is called...
stress
300
Explain the 2 different directions of shaking that are measured with seismograms/seismographs.
Left-and-right shaking 

up-and-down shaking

How do EQ's often cause fires?
During shaking, electrical wires can snap and release sparks. Gas lines can also crack, releasing flammable gas. Sparks can ignite and fires can start.
400
When would you expect to see roads cracking and buildings falling:  during a 4.9 or 8.1 earthquake?
During an 8.1 
400
The fastest and least destructive EQ wave
P-wave
400
What type of stress most often causes earthquakes?
shear stress
400
Draw a picture/diagram that displays compression stress
Answers will vary

Where was the epicenter of the EQ that occured in Delaware in November 2017?

Remember, some people in our area felt it!

Dover, Delaware
500
Explain how it is possible for a magnitude 5.1 EQ to have a greater intensity rating than a magnitude 6.8 EQ
Intensity is a measure of destruction caused by an EQ, so if an EQ occurs in a rural area where there are few buildings/urban areas, so there is less destruction.
500
What type of boundary do these lines represent?
Transform Boundary
500
What are the two types of stress cracks in rocks?
Joints and faults
500
Why did our class seismometers need marbles or weights?

Answers may vary: The marbles acted added extra weight that helped to stabilize your pen/pencil, which would create more accurate seismic recordings
