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)

    1. What is it?

    2. What is the main kind of stress occurring between the plates?

    3. What kind of fault occurs?

    4. What are earthquakes like at these boundaries?

4/25 - Make and fill-in the following table:

4/27 - From video clip at iris.edu:

    1. Why do seismometer stations each have 3 types of seismometer?

    2. What does each type measure?

    3. Which type do P and S waves both show up clearly (so we can determine lag time)?

    1. What does a CT scan (ie. CAT scan) show?

    2. How does it work?

    3. How can we use seismic waves from different earthquakes in the same way?

5/1 - From video clip at iris.edu:

    1. Why might P and S waves suddenly change direction each time they move into a new layer?

    2. Why do S-waves stop at the outer core?

5/2 - From video clip at iris.edu:

    1. What are shadow zones?

    2. Why do they exist?

    3. How is the P-wave shadow zone different than the S-wave shadow zone?
