Lesson 5: Volcanoes and Earthquakes

This is the last of the three lessons drawn from Chapter 2 that introduce background information we'll use to understand a wide range of topics later in the semester. Our focus this week is on volcanic and sesimic activity—how these processes operate, how their effects can be recognized, and how they shape the features that define so many national park landscapes.

As you read through pages 34-45 of Chapter 2 it will be helpful to take notes so that you can keep track of major points and have the information readily available when these topics arise in discussions later in the semester. Be sure that you are prepared to meet the learning objectives outlined below before you move on to the quiz at the bottom of the page.

Weekly Learning Objectives

Upon successful completion of this week's lesson, a student is expected to be able to:

Reading and Browsing Assignment

Exercise 5 (Due by 9:00 AM on Monday, 15-Feb-2010)

After you have read the last part of the chapter and are comfortable with the concepts outlined in the learning objectives above, point your browser to Virtual Courseware's Earthquake exercise. Under "Main Activities" on the first screen, click "Travel Time" and work through the exercise by following the instructions and using each tool in sequence to construct a travel time diagram. Like the earlier radiometric dating exercise you worked on this one uses Java applets that may take a little while to load; be patient. At the end of the first part of the exercise return to the main screen (you do not need to save your results from the first part.)

Next, work through the "Epicenter and Magnitude" exercise (third button under "Main Activities".) At the end of this part of the exercise you will be asked if you want to take a quiz. Click yes, fill in your name, and enter 1513648 as your class code. (Write this number down now so that you have it when you go to the Earthquake site.) Complete the 10-question quiz. When you are done you will be able to review your score, and the program will automatically post a copy of it to a grade book that I will access next Monday (15-Feb-2010). When you've finished both parts of the exercise and taken the associated quiz, you'll be finished with Exercise 5. Have fun—this is a very cool way to learn about how seismologists determine the locations and magnitudes of earthquakes.

Quiz 5 (Due by 9:00 AM on Monday, 15-Feb-2010)

After you feel you have met the learning outcomes outlined above, please complete Quiz 5 in the Etudes "Assignments, Tasks, and Tests" tool. There are ten questions, each worth one point. If you can answer all of them correctly it means that you know your way around volcanoes and earthquakes pretty well and are ready to move on to learn about parklands shaped by continental rifting next week.
