Volcano Model Lab Analysis
1. What are the strengths and weaknesses of this volcano model? (like and not like the
real thing)
2. How were the less gassy and more gassy eruptions similar? How were they
different?
3. Pumice and Basalt are both igneous rock, based on this experiment, how do you
predict that each of these rocks are formed?
4. What type of landform do you think is made from a volcano erupting many times of
a period of years: a valley, mountain, or canyon? Explain how this would happen.
