Now, using your observations, please answer the following questions:
1.
Using the video and your text book, explain what a volcano is.
2.
Based on what you observed from the video, what do you think you might see, hear and smell near a real erupting volcano?
3.
What are some of the consequences of volcanic eruptions? How might an eruption change the surrounding the volcano?
4.
What can scientists tell from the lava at different eruption sites?
5.
Make a prediction about what causes volcanic eruptions to happen
6.
Using you textbook, please explain the difference between magma and lava.
Part II
1.) Building Vocabulary p. 193 in your book
Label the figure below with the names of a volcano’s parts.
2.) Now go to the following website and read about the three types of volcanoes and fill in the chart below, do not complete the
build your own column at this time. At the site you will need to click volcano types (on the left hand side)

(quiet vs. explosive)
a.
What factors might contribute to creating different types of volcanoes and eruptions?
b.
Now click on build your own volcano and watch it erupt. Try to build each type of volcano by adjusting the viscosity and gas
settings. Record the setting and type of eruption that results on your chart.
c.
What two factors determine if an eruption is quiet or explosive?
d.
Describe a quiet eruption, what conditions (temp. and silica) are necessary, what types of lava are produced, where do they
mostly occur?
e.
Describe an explosive eruption, what conditions (temp. and silica) are necessary, what causes it, where do they mostly
occur, what is volcanic ash, what are bombs?
** There is also a 4th type of volcano that can be created, if you find it, you should fill in its information on the Volcano
types organizer.
Part III
Go to the website below and watch the 2nd and 3rd video clips, “How to Build and Island from Scratch” and “Creating and Island
Paradise”, then complete the questions below about the Hawaiian Islands
http://www.pbs.org/wnet/nature/lessons/feeling-hot-hot-hot/video-segments/1533/
Hawaiian Islands
1. What is a hotspot? How does it form? Does it form at a plate boundary (this is also in text)
____________________________________________________________________________________________________________
____________________________________________________________________________________________________________
2. What is the name of the plate on which Hawaii sits? _______________________________________________________________
3. In which direction does this plate move? _________________________________________________________________________
4. What is the name of the new volcano? __________________________________________________________________________
5. When will the new volcano break the surface of the ocean?
____________________________________________________________________________________________________________
6. What will the volcano look like when it emerges? __________________________________________________________________
7. What will the area surrounding the volcano look like in one hundred years? Why will it look that way?
____________________________________________________________________________________________________________
Part IV
a.) Using a highlighter, highlight the ring of fire
b.) What countries are involved in the ring of fire?
c.) What plates are involved in the ring of fire?
d.) At what type of boundary do most volcanoes occur?
e.) Where can you find some volcanoes on the map that occur at other boundaries, what type of a boundary is this?
f.) Using your textbook, tell me what an island arc is. Give me an example of an island arc. What specific type of convergent
boundary forms these landforms?
g.) What boundary leads to the formation Mount St. Helens and Mount Rainier?
Now go to the following website and complete the case study for each volcano in the chart below

Date & Type

Case Study #1:
Kilauea
Case Study #2:

Case Study #3:

Case Study #4:
Surtsey
Part V
Go to the following site and choose screen size for medium. Once there click on “Ground Deformation”
http://volcanoes.usgs.gov/about/edu/predict/index.php
a.
Write down three factors considered by the USGS scientists in predicting volcanic eruptions.
b.
Read and watch animations on the remaining pages of the Ground Deformation section and answer the following
questions.
Describe two changes that occurred on the surface of the dome as the magma moved upward?
1.________________________________________________________________
2.________________________________________________________________
In the weeks and days before the eruptions, what happened to the distance between the metal stakes?
__________________________________________________________________________________________________
How did the observations described in the previous question affect the scientists’ predictions?
__________________________________________________________________________________________________
What happened to the crater floor just before eruption?
__________________________________________________________________________________________________
Describe one method scientists use to analyze earthquake data.
__________________________________________________________________________________________________
What happens to earthquakes before an eruption?
__________________________________________________________________________________________________
Now click on “Exercise” on the left hand toolbar.
Read and review the information presented on pages 1-3, and then use that information to make predictions and choose their
actions on pages 4-6. Record your answers below
A.
