Presentation Transcript

  1. Volcano and Igneous Rock

  2. Volcanoes can occur at • Subducting boundaries • Hot Spots • Any type of climate

  3. Volcanoes • They make new land • They made the oceans • They made the air • They are deadly

  4. Other features of a volcano are • Geysers • Hot Springs

  5. Molten rock inside the Earth is called Magma

  6. Molten rock or magma that flows on the Earth’s surface is called Lava

  7. What would be a clue that a volcano might erupt? • Small earthquakes near the volcano • A bulge or tilt in the ground near the volcano

  8. The ash fall from a volcano • Can collapse buildings • Kill crops and livestock • Is very costly to clean up • Damage lungs • Pollute water sources • Travels the furthest

  9. Which type of lava is sharp and chunky? Aa

  10. Which type of lava has a glassy surface with rounded wrinkles? Pahoehoe

  11. What type of lava results from underwater eruptions? Pillow Lava

  12. The largest volcano discovered anywhere is Olympus Mons

  13. A “sleeping” volcano is classified as Dormant

  14. A volcano that is currently erupting is said to be Active

  15. A volcano that is not expected to erupt again is said to be extinct

  16. Mt. St. Helens is located in which state? Washington

  17. Have there ever been active volcanoes in Virginia? Yes

  18. A rock that is ejected from a volcano that is about the size of rice is called Cinder

  19. The largest projectiles given off by a volcanic blast are Bombs

  20. Shield volcanoes are very broad and gently sloping

  21. Volcanologists are measuring amounts of this gas/gases in hopes of predicting eruptions. Sulfur Dioxide

  22. What is the name of the first national park that was formed by a volcanic eruption? Yellowstone

  23. The Hawaiian Goddess of Fire is Pele

  24. Sunset Crater is an example of what type of volcano? cinder

  25. Mt. St. Helens and Mt. Fuji are examples of what type of volcano? composite

  26. The biggest volcanoes are what type? shield

  27. This mountain range in the Pacific Northwest has a lot of volcanos. Cascade Mountains

  28. The large explosion that occurred in 79 AD and totally destroyed Pompeii is which volcano? Mt Vesuvius

  29. California, Oregon, and Washington are part of the Ring of Fire

  30. Black volcanic glass obsidian

  31. Has gas bubbles scoria

  32. Vietnam War Memorial is made of gabbro

  33. Statues are made of granite

  34. Most abundant rock on Earth basalt

  35. The holes in some igneous rocks are caused by escaping gases

  36. How are igneous rocks formed? cooling and hardening of molten rock

  37. A rock that cools inside the Earth is classified as Intrusive

  38. Extrusive igneous rocks cools outside the Earth

  39. Cool slowly Cool inside the Earth Large crystals Intrusive rocks

  40. Extrusive Igneous Rocks • Cool rapidly • Cool outside the Earth • Small or no crystals

  41. Because granite cools below the surface of the Earth, it is an igneous intrusive rock

  42. Some extrusive igneous rocks, such as obsidian, are glassy because they cool rapidly

  43. Coarse grained rocks are formed when magma cools slowly

  44. Fine grained rocks are formed when lava cools quickly

  45. What can the cooling rate of molten rock determine in igneous rocks? The size of the grains
