  1. Notebook Lesson on Volcanoes Eric Angat Teacher

  2. Essential Question How are we affected by Volcanic eruptions?

  3. Instructions • Get your notebook. • Accomplish or answer the 16 item activity.

  4. The three types of volcanoes. • Gentle or non-explosive • eruptions of flowing lava. • widest • Most violent ( explosive) eruption. • Smallest type • Explosive or non- • explosive eruption • Biggest http://www.geology.utah.gov/teacher/tc/tc0599.htm

  5. 1. What is a crater lake? lake Crater lake – caldera filled with water.

  6. Caldera is a collapsed crater due to volcanic eruption.

  7. 2. Why do volcanoes erupt and explode? Magma is lighter than rock so it rises and comes out as lava. The pressure that it carries with it causes volcanoes to erupt and even explode when lake water comes in contact with the very hot lava.

  8. 3. Describe a Lava Flow. Lava flow is molten rock flowing from the slope of the volcano.

  9. 4. What is a volcano? http://www.youtube.com/watch?v=reNz6CIKE00

  10. 5. How do volcanic islands form? http://www.youtube.com/watch?v=RMtuTfAqAbo

  11. 6. What is lahar? http://www.youtube.com/watch?v=RStpgsLkhhY

  12. Lahar in Japan

  13. A lahar is a volcanic rocks, ash and water that flows rapidly along a slope.

  14. Effects of lahar? Lahars are extremely deadly destructive they can destroy any structures in their path.

  15. Lahars can destroy forests.

  16. Lahars can bury communities with debris.

  17. Lahars can block tributary streams. Tributaries are water channels that supply water to the river.

  18. d. Lahars can lead to increased deposition of sediment. Deposition of sediment makes rivers shallow.

  19. 7. What is lava? http://www.youtube.com/watch?v=egEGaBXG3Kg

  20. 8. What is pyroclastic cloud? http://www.youtube.com/watch?v=yvG_N7eqMWk

  21. 9. What is pyroclastic flow? http://www.youtube.com/watch?v=Bz7WCttwXQk

  22. Pyroclasticrefers to the masses of rock fragments and gases from a volcano.

  23. 10. How are islands created?

  24. 11. Why do volcanologist study the gases from volcanoes? 12. Where do volcanic gases come from?

  25. Volcanic gases

  26. 13. Copy the following and use Venn diagram to show the similarities and differences between lava flow, pyroclastic flow, and lahar. Lava flow - the flow of molten rock from a volcano 2. Pyroclastic flow - a fast moving cloud of hot ash, gases, and rock from a volcano 3. Lahar - a fast moving flow of muddy water form a volcano

  27. Pyroclastic flow Lava Molten rocks Fast moving volcanic ash and rocks All three are from volcanic eruptions. Lahar Fast moving flow of muddy water

  28. Draw this picture in your notebook.
