Introduction

You have been chosen to help a newly wed couple decide where to buy their new house.  The only problem is they only have two choices.  One is in a volcano zone and the other is in an earthquake fault! How will you help me choose? Perhaps you want to know whether earthquakes or volcanoes are more powerful. Or how often earthquake and volcanoes occur. Maybe you need to determine why earthquakes and volcanoes occur. There is a lot of information you are going to need to help yourself make this very important decision.  
 
The Quest (ion)
You will gather resources to help you decide whether the newly weds should live near an earthquake fault or near a volcano?


The Process and Resources

In this WebQuest you will be working individally.  You will only need to use the links provided on this webpage to help you find the information you will need to help you make your decision.  

Phase 1 - Background: Something for Everyone

In your notebooks, answer the following question using the Internet resources linked below.
1.    Who studies volcanoes?
2.    What is a volcano?  
3.    What are the 3 ways volcanoes are formed?
4.    Where does each of these volcanoes form?
5.    How do we predict a volcanic eruption?
6.    Who studies earthquakes?
7.    What is an earthquake and what causes them to happen?
8.    When do earthquakes occur?
9.    At what depth do earthquakes occur?
10.    What is the relationship between faults and earthquakes?
11.    Can we predict an earthquake?

Volcanoes

Earthquakes

Phase 2 - Looking Deeper from Different Perspectives

1. Individuals will explore the questions below.  Each set of questions will provide you with information about either a volcano or an earthquake.

2. Read through the files linked to the questions.  There will be no printing, so make sure you answer the questions in complete sentences.


Volcanologist Questions

Write the answers to these questions in your notebook.  Please write in complete sentences (The best way to do this is to use part of the question as the beginning of your answer).  Use the Internet resources linked below to answer the following questions specifically related to Volcanoes:

1.     Where are the earth's active volcanoes located on the Earth's surface?
2.    Are most volcanoes located near the edges or near the centers of continents?
3.   List 5 major cities in the United States which are located on or near active volcanoes?
4.    How powerful is a volcanic eruption?

5.    What effect does a volcano have on the surrounding area?
6.    What types of updates are provided before a volcanic eruption occurs?

The Resources

     Effects of Volcanoes
•     The Global Volcanism Program
•     Prominent Hot Spots on the World Map
•     Illustration of the Earth's plate boundaries and location
•     Active Volcanoes of Alaska
•     Western United States Map of Active Volcanoes
•     Active Volcanoes of Hawaii
•     How Often Does an Eruption Occur?
•     Volcanoes

Seismologist Questions

Write the answers to these questions in your notebook.  Please write in complete sentences (The best way to do this is to use part of the question as the beginning of your answer).  Use the Internet resources linked below to answer the following questions specifically related to Earthquakes:

1. Is there any pattern to the location of earthquakes?
2. Which major cities in the United States are located in earthquake zones?
3. What is the range of magnitude for earthquakes?
4. How often did earthquakes with magnitudes greater than 5 occur in the World this year? In the US this year?
5. What effect do earthquakes have on the surrounding area?
6. What kind of prevention plans are used to reduce earthquake damage? (Give 2 or 3 examples)
 


Phase 3 - Real World Feedback

You and your teammates have learned a lot by dividing up into different roles. Now's the time to put your learning into a letter to the newly wed couple.  Your letter should contain your group’s opinion, information, and perspectives.  Here's the process:
1. Begin your letter with a statement of who you are and why you are writing them this letter.

2. State the task / Quest (ion) and your answer.

3. You should write a paragraph that gives two good reasons supporting your opinion. Make sure to be specific in both the information (like where you got it from on the Web) and the reasoning (why the information proves your point).

4. Have each person on the team proofread the message.

  Conclusion


You should have quite a bit of information about both earthquakes and volcanoes so, where do you want to live? Near an earthquake or a volcano? Remember, learning never stops.
