11.1. Volcanism – Learning Outcomes

After reading this chapter of the textbook, learning the vocabulary, and working through the review questions, students should be able to:

• Define volcanism.
• Describe the key characteristics of a volcano.
• Explain how the viscosity of lava changes with magma composition and why.
• Explain how the shapes of volcanos and the types of volcanic materials that make them up vary with magma composition.
• Describe the different types of volcanic eruption and name volcanoes where these eruptions have occurred.
• Describe the different kinds of tephra and volcanic textures and how they form.
• Describe the hazards associated with volcanoes.
• Describe the relationship between volcano type, composition, and tectonic environment.
• Describe how volcanoes interact with the atmosphere and the hydrosphere.
• Describe where we find volcanoes in Canada. Provide examples of these volcanoes and describe the plate tectonic environments where they form.

Learning outcomes not covered in the textbook chapter in detail, but we may discuss them in class (depending on your professor):

• Describe the difference between a central vent volcano and a large-scale volcanic terrain.
• Name the major types of volcano. Describe each type of volcano.
• Provide an example of a place in the world where you find each type of volcano.
