I. Different Types of Volcanoes A. Shield Volcanoes B. Cinder Cone Volcanoes C. Composite Volcanoes Types of Volcanoes Video Clip Nat Geo Volcanoes http://www.nationalgeographic.com/forcesofnature/interactive/index.html A. Shield Volcanoes Shield Volcanoes are built of layers of lava released from repeated non explosive eruptions. Example Hawaiian volcanoes are examples of shield volcanoes. B. Cinder Cone Volcanoes Cinder cones are made up of pyroclastic materials. Have Erode steep slopes quickly Example: Mexico’s Paricutin C. Composite Volcanoes Contains alternating layers of pyroclastic material and lava. Broad steep. bases, Examples: Mt Fuji, Mt St. Helens, and Mt. Rainier Review Question Which type of volcano usually erupts violently and forms because of alternating layers of ash, cinders, and lava? How does a shield volcano form? Shield Volcano Cinder Cone Volcano Composite Volcano Where do most Volcanoes Occur? At Tectonic Plate Boundaries Hot Spots Hot spot: a volcanic active area of Earth’s surface far from a tectonic plate boundary. Hot Spot Volcano Tracks
