2 Folder 1: Seismic Waves Instructions Step 1. Click on the radio buttons next to Inv 3: Seismic Waves and Introduction. Double click on Introduction to open the balloon. Read the information. Then click on the X in the upper right hand corner of the balloon to close it. 2. Expand Folder 1: Seismic Waves. Open the Description placemark balloon. Read the information and watch the animation. Answer the questions in the Observations section. You will need to refer to this information later. 3. Use your observations to answer the Investigation question. You can look back on the notes you took on the San Francisco earthquake to help. Complete Observations What are seismic waves? What are body waves? What are surface waves? What are S waves? What materials S waves can travel through: What are P waves? What materials P waves can travel through: What are rocks composed of? What are minerals composed of? What is elasticity? CE3 T eacher s G uide - Module 2 Page 25

3 Interpretation In the 1906 San Francisco Earthquake, which areas experienced seismic waves of the highest amplitude? Reasoning: Folder 2: Locating Earthquakes Instructions Step 1. Expand Folder 2: Locating Earthquakes and click on the radio button. Each red dot that you see represents an actual seismograph station. These are the stations record the seismic waves caused by earthquakes. Use the zoom and rotate tools to explore the overlay. Are the stations randomly distributed? Record your observations. 2. Fly to your town and find the station nearest to you. Click on it to see its name, location, and status (whether it is active or inactive). Use your ruler tool to find out how far away it is. Record your findings. 3. Open the 2010 Chilean Earthquake folder and Description placemark balloon. Read the information and record any information you can in the Observations section. Close the balloon. 4. Open the Chilean Earthquake Data folder and click on each of the three seismic stations shown. These are just a few of hundreds of stations that recorded the large Chilean earthquake of Record the lag time at each station in the table in the Observations section. 5. Using the Ruler tool, measure the distance from the earthquake epicenter to Complete CE3 T eacher s G uide - Module 2 Page 26

4 each of the three stations. Record these values to the nearest 100 km in the table. Hint: You may need to rotate the globe before completing your line for the sites farther away. 6. On the graph paper provided, graph the distance vs. lag time for the three stations. You should have three points on your graph. Label each one with the name of the station. Then use a straight edge to draw a line connecting the three dots. Study your graph and record your findings. 7. Fly to London, UK. Use your ruler tool to measure the distance from London to the Chilean earthquake epicenter. Find this distance on the x- axis of your graph. Use the line you drew to predict what the lag time would have been for a seismograph station in London, UK. Record your findings. 8. Think back to the San Francisco earthquake to answer the interpretation question. Be sure to use complete sentences. Observations How many seismograph stations are there worldwide tens, hundreds, thousands, or tens of thousands? Are the stations randomly distributed? If not, what patterns do you see? Which seismograph station is closest to your town? How far away is it? What is lag time? 2010 Chilean Earthquake Data Station Lag Time (minutes) Distance (km) Paso Flores, Argentina Llaves, New Mexico Tiksi, Russia CE3 T eacher s G uide - Module 2 Page 27

5 Graph of distance vs. lag time for the three seismograph stations. Is the relationship between lag time and distance relatively constant? What approximate distance does each minute of lag time represent? Distance from London, UK to the Chilean earthquake epicenter (to the nearest 1000 km): What lag time would be expected at a seismograph station in London recording the Chilean earthquake? Interpretation What could affect the lag time between the arrival of S and P waves, other than distance from the epicenter? Do you think the computer models scientists use to locate earthquakes consider this? Reasoning: CE3 T eacher s G uide - Module 2 Page 28

6 Folder 3: Exploring Earth s Interior Instructions Step 1. Expand Folder 3: Exploring Earth s Interior and click on the radio button. Open the Description placemark and read the information. Then close the balloon. Complete 2. Study the diagram above. Record your observations. 3. Mohorovicic saw that the speed of seismic waves increased 50 km below the surface. He knew that seismic waves travel faster in denser material. Therefore, he reasoned that Earth s upper mantle must be denser than the crust. Using the same line of reasoning, answer the interpretation questions. 4. Open and read the Summary placemark balloon. Then answer the questions CE3 Teacher s Guide - Module 2 Page 29

7 in the Investigation Summary. Be sure to use complete sentences. Observations Name Earth s five major layers. Which layer is the asthenosphere part of? What is the lithosphere made of? What happens to the speed of seismic waves when they leave the lithosphere and enter the asthenosphere? What happens to the speed of seismic waves when they leave the asthenosphere and enter the lower part of the upper mantle? What happens when seismic waves move from the upper mantle to the lower mantle? What happens to seismic waves when they enter Earth s outer core? Interpretation How dense do you think the asthenosphere is compared with the layers above and below it? Reasoning: CE3 T eacher s G uide - Module 2 Page 30

8 Is the lower mantle more or less dense than the upper mantle? Reasoning Is the outer core liquid or solid? Reasoning: CE3 T eacher s G uide - Module 2 Page 31

9 Investigation Summary Why are seismic waves able to move through rock? What is the most destructive type of seismic wave? How are earthquake hypocenters located? What can studying seismic waves tell us about Earth? CE3 T eacher s G uide - Module 2 Page 32
