1. Notebook Lesson on Volcanoes Eric Angat Teacher

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

3. Instructions 1.Get your notebook. 2.Accomplish or answer the 16 item activity.

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

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

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 https://www.youtube.com/watch?v=kznwnpNTB6k

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

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

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

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

23. 10. How are islands created? https://www.youtube.com/watch?v=RMtuTfA qAbo

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

25. Volcanic gases

26. 1.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 13. Copy the following and use Venn diagram to show the similarities and differences between lava flow, pyroclastic flow, and lahar.

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

28. Draw this picture in your notebook.
