1. Identify and describe the two primary factors that determine whether a volcanic eruption is relatively violent or not, and how these factors relate to the viscosity of a magma. (What determines magma viscosity?)
2. For the three main types of volcanoes (composite, shield, cinder cone), describe each (size, shape, eruption violence)
3. For each type of volcano (Q2), identify and describe the threats posed and the relationship of the threat to magma viscosity Q1).
4. How are volcanic activity, in general, and plate tectonics related?
5. How can volcanoes be monitored in order to predict eruptions?
