Pre-Lab Study Guide
1. Be able to explain the roles elastic and brittle behavior play in earthquakes, and how
ductile and brittle behavior can be used to interpret past stress events.
a. Brittle deformation creates different types of faults and certain faults can causes
some elastic deformation and it causes the earthquake
b. Because brittle and ductile behavior are permanent they leave specific marker
that can be analyzed to show past stress event
2. Be able to explain how seismograms can be used to identify an earthî†‹uakeâ€™s location
aî…¶d how geologists use that iî…¶foî†Œî…µatioî…¶ to deteî†Œî…µiî…¶e aî…¶ eaî†Œthî†‹uakeâ€™s locatioî…¶.
a. P-waves and S-waves travel at different speeds, the difference in their arrival
times at a seismic station allows geologists to determine the distance between
the station and a seismic event. The difference in arrival times between the first
P-wave and the first S-wave is proportional to the distance from the epicenter to
the station.
3. In particular, know the minimum number of seismic stations needed to locate an
earthquake

4. what specific information the seismographs record
a. A seismic wave shakes a seismogram base and creates a relative motion that is
recorded and can determine its position
5. Which types of stresses dominate each of the following plate tectonic boundaries:
divergent, convergent and transform? If rock behaves in a ductile manner, which types

#### Loved by over 2.2 million students

Over 90% improved by at least one letter grade.

OneClass has been such a huge help in my studies at UofT especially since I am a transfer student. OneClass is the study buddy I never had before and definitely gives me the extra push to get from a B to an A!

Leah â€” University of Toronto

Balancing social life With academics can be difficult, that is why I'm so glad that OneClass is out there where I can find the top notes for all of my classes. Now I can be the all-star student I want to be.

Saarim â€” University of Michigan

As a college student living on a college budget, I love how easy it is to earn gift cards just by submitting my notes.
