EARTHQUAKE WEBQUEST



EARTHQUAKE WEBQUESTNAME_______________________________________________________TASK #1 this website to answer the following questions. Make sure the questions are answered in complete sentences!Around 1912, German meteorologist Alfred Wegener developed a theory called continental drift. He believed that about 225 million years ago, giant landmasses gradually shifted and broke apart to form the continents as we know them today. How many original "supercontinents" did Wegener's theory of continental drift assume? The Earth's crust is made up of a series twelve interconnected landmasses are called tectonic plates. What are the major plates that affect the United States? Check out this hazard map showing probability for earthquakes. Why do you think California has so many earthquakes but Florida doesn't? In what hazard zone is your home located? What is considered to be the most destructive earthquake in history? When did it occur, where was it, what was its magnitude and how many people died? What are the three basic types of plate boundaries? Describe each briefly. What are tsunamis, what causes them and how fast do they travel? What are the two types of energy waves created by an earthquake and how do they differ? Which type of wave travels faster? What are the two types of surface waves produced by an earthquake?How much more energy is released by a 7.2 earthquake than by a 6.2 earthquake? What applications does seismology have besides measuring the magnitude and location of earthquakes? Where did most of the earthquakes happen last week? Can scientists predict earthquakes? How do scientists know where an earthquake actually occurred? Mr. Hansen’sInitials TASK #2 Please understand that you MUST CAREFULLY READ EVERYTHING and DO THE EXAMPLE PROBLEMS to see if you understand HOW they got the answer. Be very careful with your calculations because accuracy is a must and will keep you from completing this assignment correctly. When you are done with the assignment you will be asked to enter your name (FIRST & LAST Please!) to print off a certificate of completion – You must show me your certificate and have me initial above in order to get credit for the assignment. You DO NOT need to print it off. Just raise your hand and call me over when your certificate is up on the screen (with your date and data listed on it) and I will initial above. Please make sure that this certificate has your data and the actual data comparison chart underneath it as well as your name or you will NOT get credit for this assignment. TASK #3 completing the initial virtual earthquake, you are now ready to make your own measurements. First click on “Main Activities: Demonstration.” Go through the demonstration on how to use the tools for the Travel Time and Epicenter and Magnitude Activities. Once complete with the demonstration, complete the Travel Time Activity and Epicenter and Magnitude Activity. When finished with both activities, print the lab sheets for credit.TASK #4 you prepared? Use the article to answer the following questions:What is earthquake magnitude?If an earthquake measures a 4.0 how much more powerful is this earthquake than one that measured 2.0? (use the example listed with the definition to help you calculate the answer)Answer = ______ times more powerfulTake the Knowledge Check by reading the questions and writing the correct answer (letter) below.____________________________________I will check these for correctness – use the article to help you determine the best place to go during an earthquake.Write down two protective measures (from the many listed here) that you feel are the most important for you to take care of in the following situations:Before an earthquake I… During an earthquake I... After an earthquake I… ................
