1.Describe in words the relationships between lava chemical composition, lava viscosity, and volcano shapes. Illustrate your answer with sketches of at least two types of volcano shapes.
2.In words and/or diagrams, compare and contrast strombolian and Plinian eruption styles. Be sure to address the relative magnitude (how much material is erupted?), eruption duration (how long does it last?), how explosive the eruption is, and the types of erupted materials.
3.Name and describe three tectonic environments in which volcanism occurs. For each environment, briefly describe the primary magma generation mechanism (with or without accompanying diagrams, as needed).
4.Explain in words how Bowen’s Reaction Series (BRS) works, and how it results in lavas with different chemical compositions. List two physical characteristics that differ between the initial lava and the final lava produced near the end of the fractional crystallization process. What rock names would you give to each of those lavas (i.e.., the initial and final products) if they erupted? Be sure you are clear about which is which.
