Before starting Volcanoes, briefly review plate tectonics with the following link:
- follow the link below, read the pages, and then answer the questions.
2. Anatomy of a Volcano
- How do volcanoes form?
- What are the four primary types of volcanoes? Name and describe each type in detail. Encourage students to sketch the shape of each type and note its plate tectonic setting (i.e., over hot spots, spreading centers, or subduction zones).
- Where do volcanoes form?
- Rocks are classified by what they are made of and how they form. Igneous rocks always begin as magma. What are the two main types of igneous rocks, and what is the main difference between them? How does each type form into solid rock?
This is a short animation. Take a look at it before going to the second link below and answering the questions.
- How do lava tubes form, and where are they most likely to be found?
- What is the difference between how two common cave features -- stalactites and stalagmites -- form in limestone caves and how they form in lava tubes?
- Besides stalactites and stalagmites, choose three lava tube features that interest you, and explain how they form.
