  1. Volcanoes and Earthquakes!

  2. Warm Up • Why do you think magma rises? Consider an ice cube floating at the top of a glass of water

  3. Objective: • SWBAT • Describe at least two of the three types of volcanoes and how they form • Agenda: • Weather • Guided Notes: 3 Types of Volcanoes • Volcano Articles • Raging Planet: Volcanoes • Closing • Homework: • Finish Article Questions and transfer answers to Chart

  4. Weather

  5. Guided Notes: 3 Types of Volcanoes • Shield • Forms on hot spots • Broad base, small incline • Enormous height (including base below sea level) • Thin lava makes it the least explosive • EX: Mauna Loa in Hawaii • Cinder • Cone-shaped mound of ash • Smallest • Forms on sides of other volcanoes • Forms in groups • EX: Capulin in New Mexico, Mount Paricutin in Mexico • Composite (Stratovolcano) • Creates lahars (mudflows/landslides) • Forms from layers of lava (from many eruptions) • May remain dormant for long periods between eruptions • Thick lava makes it the most explosive • EX: Mount St. Helen’s in Washington, Mount Vesuvius in Italy

  6. Volcano Articles • Working individually, read the following articles and answer the accompanying questions

  7. Raging Planet: Volcanoes • While watching the Raging Planet: Volcanoes, answer the questions on your worksheet

  8. Warm Up • How does a volcano’s amount of activity relate to it’s explosiveness? • How does a volcano’s magma temperature relate to it’s destructive potential?

  9. Objective: • SWBAT • Explain why scientist’s study seismic waves • Agenda: • Earthquake Survival • Notes: Seismic Waves • Slinky Demonstration • If time: Finish Raging Planet: Volcanoes • Closing • Homework: • Extraterrestrial Volcanoes

  10. 1999 Earthquake in Adapazari, Turkey • What kind of destruction can you see? • What kind of destruction may have occurred that you cannot see?

  11. Earthquake Survival Activity • Ms. McGowan will split you into groups of 4 • In your groups, take turns reading the Earthquake Survival Script • Then, work together to determine what actions you would take post-earthquake

  12. Notes: Seismic Waves • Body Waves—travel through Earth’s interior • P waves • Particles move parallel to wave • Travels through anything • Fastest speed • S waves • Particles move perpendicular to wave • Only travels through solids • Medium speed • Surface Waves—travel through Earth’s surface • Slowest speed

  13. Seismic Waves Slinky Demonstration • Follow along on your Seismic Waves Demonstration Worksheet as Ms. McGowan demonstrates seismic waves with her slinky

  14. Raging Planet: Volcano • Take out your Raging Planet: Volcano Questions Sheet • Answer your questions as we finish watching the video • Follow along as Ms. McGowan reviews the answers

  15. Closing • Surface waves travel the slowest. Are they still dangerous? Provide support for your answer.
