Summary
In this unit, you have learned what a volcano is and how to distinguish among different types of volcanoes, such as shield volcanoes, cinder cone volcanoes, and stratovolcanoes/composite cone volcanoes. You've also learned how to describe the physical and eruptive characteristics unique to each volcano, the types of rocks resulting from their eruptions, and the solidification of their magma. These characteristics and rock types are related to the type of magma, mafic or intermediate-felsic, responsible for creating the volcano. The magma, in turn, is the product of the plate tectonic setting for each volcano. You've also learned a little about one of the most dangerous products of an eruption, the pyroclastic flow, and one of the most spectacular landforms made from volcanic activity, a caldera. Finally, you should be able to describe why some volcanoes explode instead of simply erupting and why volcanic eruptions are a geologically constructive process.

Learning Objectives
- Students can describe the eruptive and physical characteristics of different types of volcanoes
- Identify and describe how calderas form
- Describe the intrusive and extrusive rocks associated with each volcano
- Explain why some volcanoes explode while others do not
Types of Volcanoes
The table summarizes some of these important concepts.
Volcano Type |
Size and Shape |
Magma Composition |
Eruption Type |
Extrusive Rock |
Intrusive Rock |
Plate Tectonic Setting |
|---|---|---|---|---|---|---|
| Shield | Short to very tall; gentle slopes | Mafic | Quiet | Basalt | Gabbro | Hot Spots; continental rift zones |
| Cinder Cone | Short; steep-sided | Mafic | Quiet | Basalt, scoria | Gabbro | Hot Spots; continental rift zones, convergent boundaries |
| Composite Cone | Tall; steep-sided | Intermediate-felsic | Explosive | Pumice, andesite, rhyolite, tuff | Diorite, granite | Convergent boundaries |
