Earthquakes & Earth Layers 4/20 - 5/15
Post date: Apr 20, 2017 5:41:21 PM
Objectives
Identify three types of stress and associate them with three types of fault and tectonic plate boundary.
Geographically identify examples of stress, faults and tectonic plate boundaries.
Identify the properties of body waves and surface waves that relate to the magnitude and intensity of earthquakes.
Apply the properties of body waves to triangulate earthquake epicenters and map the interior of the earth.
Explain how we know what is inside the earth.
Identify ways to make damage less severe and protect yourself during earthquakes.
Describe the layers of the earth by chemical composition and physical properties.

4/20 - What is an Earthquake? Make a picture with the following terms labeled: fault, focus, epicenter, seismic waves. (DE pgs. 240-241, 254-255)
Earthquake 101 - nationalgeographic.com
4/24 - Convergent Boundary: (DE pg. 243)
What is it?
What is the main kind of stress occurring between the plates?
What kind of fault occurs?
What are earthquakes like at these boundaries?
4/25 - Make and fill-in the following table:
4/27 - From video clip at iris.edu:
Why do seismometer stations each have 3 types of seismometer?
What does each type measure?
Which type do P and S waves both show up clearly (so we can determine lag time)?
4/28 - From video clip at iris.edu:
What does a CT scan (ie. CAT scan) show?
How does it work?
How can we use seismic waves from different earthquakes in the same way?
5/1 - From video clip at iris.edu:
Why might P and S waves suddenly change direction each time they move into a new layer?
Why do S-waves stop at the outer core?
5/2 - From video clip at iris.edu:
What are shadow zones?
Why do they exist?
How is the P-wave shadow zone different than the S-wave shadow zone?
5/3 - Answer the following questions for Divergent Boundary and Transform Boundary. (DE pg. 243)
What is it?
What is the main kind of stress occurring between the plates?
What kind of fault occurs?
What are earthquakes like at these boundaries?
5/4 - What patterns do you see when earthquakes are plotted over a long period of time?
SeismicEruptionSetup.exe - binghamton.edu
5/10 - List five kinds of evidence that continents move.
5/12 - What can you do to prepare for an earthquake at home? What would you do if an Earthquake happened while you were in class?
