  1. Volcanoes

  2. Types of Volcanoes Volcanoes are classified under 4 categories: Shield Volcanoes Cinder Cone Composite or Stratovolcanoes Lava Domes

  3. Shield Volcanoes • Quiet & non-explosive; • Great masses of lava quietly ooze out from an opening in the earth's crust; • Liquidy lava; • Gently sloping cone. • The largest volcanoes on earth

  4. Shield Volcanoes Mount Kilauea, Hawaii, USA

  5. Shield Volcanoes Mauna Loa, Hawaii, USA

  6. Cinder Cone Volcanoes • Explosive volcanoes; • Volcanic bombs, cinders, and ash are hurled out of an erupting volcano; • Most have a bowl-shaped crater at the summit • Some of the tallest volcanoes

  7. Cinder Cone Volcanoes Mount Etna in Italy

  8. Cinder Cone Volcanoes Tavurvur, Papua New Guinea

  9. Cinder Cone Volcanoes Mount Veniaminof, Alaska

  10. Composite orStratovolcanoes • Also called: STRATOVOLCANOES • Alternating layers of lava and cinders on earth; • Consists of many separate vents

  11. Stratovolcanoes

  12. Stratovolcanoes Mount Vesuvius Erupting (Italy)

  13. Stratovolcanoes A victim found from Pompeii

  14. Stratovolcanoes Mount Fuji, Japan

  15. Stratovolcanoes Mount Ranier, Washington, USA

  16. Stratovolcanoes Mount Hood, Oregon, USA

  17. Stratovolcanoes Mayon Volcano, Luzon Island, Philippines

  18. Stratovolcanoes Mount St. Helen’s, Washington, USA

  19. Stratovolcanoes Ararat, Turkey

  20. Lava Dome Volcanoes • Volcanic or lava domes are formed by relatively small, bulbous masses of lava that are very viscous (sticky & gooey) • A steep-sided mass • Its surface is often rough and blocky as a result of fragmentation of the cooler, outer crust during growth of the dome

  21. Lava Dome Volcanoes

  22. Lava Dome Volcanoes Lassen Park Dome Volcano

  23. Lava Dome Volcanoes Mount Pelee, West Indies

  24. Lava Dome Volcanoes Montserrat, West Indies

  25. Lava Dome Volcanoes Montserrat, West Indies

  26. Recent Volcanic Eruption Mini-research Project • Your task: • Find a recent volcanic eruption and write a small report about the volcano. • Be sure to include the name of the volcano, the type of volcano, and date of the most recent eruption, a description of the eruption, and the impact on the environment. • Use the following link to find some interesting info: • http://volcano.und.nodak.edu/vwdocs/current_volcs/current.html
