Falcon Focus

This text provides an overview of the different types of plate boundaries and their relationship to volcanic activity. It explains the processes that contribute to the formation of volcanoes and discusses the destructiveness and constructive aspects of volcanic eruptions. The text also explores why the study of volcanic activity is important for understanding plate tectonics. Lastly, it includes information on different types of volcanic formations and their occurrence at convergent boundaries, divergent boundaries, and hot spots.

Presentation Transcript

  1. Falcon Focus Match the vocabulary to it’s definition • 1. Convergent Boundary __ • 2. Divergent Boundary __ • 3. Transform Boundary __ • 4. Fault __ • 5. Boundary __ a. A break in the Earth’s crust b. Where two plates meet c. Two plates divide d. Two plates slide past each other e. Two plates collide

  2. ESSENTIAL QUESTION • ACADEMIC: HOW ARE VOLCANOES FORMED? • HONORS: WHAT PROCESSES CONTRIBUTE TO THE FORMATION OF VOLCANOES?

  3. Volcanoes 101

  4. In your table groups: • Complete • MAPPING VOLCANOES • activity 2. Answer the questions

  5. LAVA vs. MAGMA • LAVA = Outside the volcano • MAGMA = Inside the Volcano

  6. Volcanic Eruptions • Can beDESTRUCTIVE • when an eruption is explosive it changes the landscape of and aroundthe volcano • Can beCONSTRUCTIVE • addsnew rock to existing land • formsnew islands

  7. WHY DO WE CARE? • Scientists study and volcanic activity in order to support the theory of plate tectonics. • The evidence proves that there is a distinct relationship between VOLCANIC ACTIVITY and PLATE TECTONICS (plate movement)

  8. Where do volcanos occur?When plates interact at boundaries, there is much more volcanic activity at these places. • Convergent Boundary • Subduction Zone = crust melts and magma rises through • Forms: Volcanoes and Volcanic Island Arcs

  9. Where do volcanos occur?When plates interact at boundaries, there is much more volcanic activity at these places. • Divergent Boundary • Magma pushes between plates (rift zones) as plates pull apart • Forms: NEW CRUST at Mid-Ocean Ridges and Rift Valleys

  10. Where do volcanos occur?When plates interact at boundaries, there is much more volcanic activity at these places. • Hot Spots • Surrounds the majority of the Pacific Ocean Basin • HIGH volcanic activity because of Converging plate boundaries that border the Pacific Ocean Basin • Ring of Fire is great proof of plate motion for scientists

  11. Hot Spots continued… • Hot Spots are STATIONARY (stay in one place) • Plate moves over the hot spot and a volcano forms • As plate moves, the volcano breaks away and moves with the plate • This makes room for a new volcano over the hot spot Forms: Volcano chains  HAWAIIN ISLANDS

  12. PACIFIC RING OF FIRE

  13. PACIFIC RING OF FIRE • Surrounds the majority of the Pacific Ocean Basin • HIGH volcanic activity because of Converging plate boundaries that border the Pacific Ocean Basin • Ring of Fire is great PROOF of plate motion for scientists

  14. What do underwater volcanoes look like when they erupt? (video)

  15. Falcon Focus (Academic) • 1. Describe the difference between magma and lava. • 2. Draw and label a cross-section picture of how a volcano looks on the inside: include the layers of the Earth that can be involved • Essential Question: How do volcanoes change Earth’s surface?

  16. Falcon Focus (Honors) • 1. Describe the difference between magma and lava. • 2. Draw and label a cross-section picture of how a volcano looks on the inside: include the layers of the Earth that can be involved • Essential Question: How can scientists predict volcanic eruptions and avoid hazards?

  17. Falcon Focus • Scientists want to test if the time a student sleeps can increase their math scores in school. • Formulate a hypothesis from this. • What would be the independent variable? • What would be the dependent variable? • Essential Question: What are good testing habits?

  18. Falcon Focus • (Create a story (5 sentences) about travelling into the Earth. Include the layers you see and what they are like. • Essential Question: What are good studying habits?
