Chapter 1 Study Questions

Chapter 5: Study Questions
1. Define magnitude, intensity and duration? How are each of these classification
schemes meaningful? Are there drawbacks or difficulties with any of them?
2. What is the essence of each of the eruption styles described in textbook and in
class? Why is it useful to use eruption style terminology in describing current and
past volcanism?
3. What is the Walker classification method of eruption styles (see online lecture
slides)? Why do you think it is useful? What are its limitations?
Chapter 13: Study Questions on Volcanic Landforms
1. How would you describe with words and sketches each of the volcano types in the
textbook and powerpoint slides? Be able to describe in terms of shape, size,
eruptive style(s), type of material erupted in terms of composition and lithology
(i.e. pyroclastic density current deposit, fine grained tuff, lava) ?
2. As you saw in lab 2, some volcanoes erupt many different compositions of
magma. Which types? Why is that? How does that affect the resulting volcanic
3. What does inverted topography refer to? Make a series of sketches that illustrate
the process of topographic inversion of volcanic landscapes.
