9. Three Types of Volcanoes 2. Shield volcano: made of slow lava flows

10. Three Types of Volcanoes 3. Composite volcano: made of slow lava flows and explosive eruptions of cinders

11. Three Classifications of Volcanoes: 1. Active Volcano: has erupted recently or might erupt soon

12. 2. Dormant volcano: has been quiet for a long time, but still has signs it may erupt again (still has a magma chamber)

13. 3.Extinct volcano: has not erupted for thousands of years and cannot erupt again (magma chamber gone)
