  1. Volcanic Jeopardy!

  2. Volcanic Jeopardy! Final Jeopardy

  3. Which of the following is not part of a volcano? Pipe Vent Neck Crater

  4. Which of the following is not part of a volcano? Pipe Vent Neck Crater Back to Menu

  5. Molten rock has two different names. Explain.

  6. Magmais molten rock that has not reached Earth’s surface. Lava is on Earth’s surface. Back to Menu

  7. How are the Pipe, Vent and Crater related?

  8. Magma flows from the magma chamber up the Pipe. The Vent connects the Pipe and the Crater, the bowl-shaped area where lava collects. Back to Menu

  9. Most volcanoes form along subduction boundaries. How does a subduction zone cause volcanoes and what is the famous name for it?

  10. The Ring of Firewhere older, colder, denser crust sinks below newer, warmer, less dense crust. Plunges back into the mantle, forcing magma upwards. Back to Menu Final Jeopardy

  11. Scientists are not yet able to definitely predict when a volcano will erupt, but they can often feel it coming. How?

  12. Small earthquakes frequently happen before an eruption. Volcanoes are also monitored with laser ranging. Back to Menu

  13. What does this picture represent? Describe it.

  14. Pyroclastic Flow– a mix of volcanic projectiles that is incredibly hot and is moving hundreds of mph. Back to Menu

  15. What dangerous hazard could this snowy volcano create? DAILY DOUBLE!

  16. A Lahar, a destructive mudslide caused by rapidly melting snow that picks up debris as it flows. Back to Menu

  17. Describe the projectiles ejected from a volcano.

  18. Volcanic Ash:Rocky, sand-sized particles • Cinders:Pebble-sized particles • Bombs:Large pieces of rock Back to Menu Final Jeopardy

  19. What are the two types of Volcanic Eruptions?

  20. Eruptions can be Quiet(lava oozes out the volcano calmly) or Explosive(lava forces its way out violently, raining projectiles). Back to Menu

  21. What is Viscosity? Give an example of a fluid with high or low viscosity.

  22. Viscosity is a fluid’s resistance to flow. Water has low viscosity, syrup has high viscosity. Back to Menu

  23. What are the 3 types of Volcanoes? Explain how they are different.

  24. Shield: gentle slope, low pressure, and quiet eruptions. Cinder Cone : steep slopes, high pressure, explosive eruptions. Composite: not as gentle as shield, not as steep as cinder; both quiet & explosive eruptions. Back to Menu

  25. How does Silicaaffect Viscosity of magma? How does Viscosity affect the type of eruption and why?

  26. More Silica increases Viscosity . High Viscosity means explosive eruption because gases trying to escape the magma must FORCE their way out – like opening a stubborn bag of chips. Back to Menu Final Jeopardy

  27. Explain the difference between a Sill and a Dike.

  28. Sill is a horizontal layer of hardened magma. A Dike is a vertical layer. Back to Menu

  29. Explain how a Calderaforms.

  30. A Caldera forms when a volcano erupts and empties its magma chamber, it collapses. The pit left behind can fill with water. Back to Menu

  31. What are the stages of a volcano’s life cycle?

  32. A volcano that is live and shows signs of erupting in the future is called Active. A sleeping, potentially active volcano is Dormant. A volcano that is unlikely to erupt again is called Extinct. Back to Menu

  33. What are structures Aand B? What do they have in common.

  34. Ais a Batholith. B is a Volcanic Neck. Both form as magma cools and solidifies into rock. Back to Menu Final Jeopardy

  35. A location where magma burns through the crust like a blow torch is called…

  36. A Hot Spot. Back to Menu

  37. How does an Island Arc form? Give an example of one.

  38. A hot spot forms an island. The plate moves along like a conveyor belt, creating a string of islands – Hawaii. Back to Menu

  39. What are these two features? How are they similar? Different?

  40. A Hot Spring and Geyser, both heated by magma near the surface. Pressure builds up underneath a Geyser, causing gas to rush up and shoot water. Back to Menu

  41. The largest known volcano is…

  42. Olympus Mons, located on Mars. As large as the entire state of Ohio. Back to Menu Final Jeopardy
