  1. This is your cover page. Cut & discard this portion. Types of Volcanoes Joseph Cardone

  2. Cinder Cones Cinder Cones Cut & discard this portion! • Simplest of the volcano types • Built from congealed lava flowing from a single vent • Magma is spewed violently into the air and the cinders fall and collect around the vent. • Usually have a bowl-shaped crater • Common in western North America Photos from the United States Geological Survey (http://pubs.usgs.gov/gip/volc/types.html)

  3. Composite Cut & discard this portion! Composite • Steep-sided, symmetrical cones • Form grandiose mountains • Magma is delivered from the earth through a conduit • Cones may be eroded over time • Ex: Mt. Hood & Mt. St. Helens Cut & discard this portion! Photos from the United States Geological Survey (http://pubs.usgs.gov/gip/volc/types.html)

  4. Shield • Built almost entirely from fluid lava flows • Make up some of the largest volcanoes in the world • Hawaiian Islands are a chain of this type of volcanoes • Lava flows out of central vent and rift zones to form a broad field of lava Cut & discard this portion! Shield Cut & discard this portion! Photos from the United States Geological Survey (http://pubs.usgs.gov/gip/volc/types.html)

  5. Lava Domes Cut & discard this portion! • Small masses of lava that are too thick to flow very far • Lava piles up and over its vent • Lava cools, hardens, then fractures, spilling fragments down its sides • Common within the craters of larger composite volcanoes Lava Domes Photos from the United States Geological Survey (http://pubs.usgs.gov/gip/volc/types.html)
