4. A Cinder Cone volcano looks like this.

5. What is a steep, cone shaped dome?
T/F: Cinder cones rarely exceed 1000 feet in height
Answer is under here
True. Except for a rare one in Mexico in the mid-1940’s, which was 1200 feet tall and just popped up out of nowhere, most never exceed 1000 feet in height. Go to this link and you can see a picture of it is you scroll down a bit:

14. Krakatoa was located here. (Country)

15. Why is Krakatoa a notable volcano?
What is Indonesia?
Why is Krakatoa a notable volcano?
Answer is under here
The huge explosion (blast) that was heard nearly around the world

16. All of these volcanoes can have heavy metals (beyond iron) in them, just like you do. Where did those heavy metals come from?

17. Meteors that hit the earth as meteorites.
Where did the meteors come from?
Answer is under here
Supernovas - which are large stars that explode.

18. Mount Shasta is here.

19. What is California?
Since Vesuvius is big, but in not on top of a hot spot, it is most likely a ____ volcano
Answer is under here
Composite/Stratovolcano

20. Yellowstone, with its monstrous caldera, is an example of this type of volcano?

21. Supervolcano! It is not a shield or composite volcano (since there is not structure above the ground), just a giant caldera for a hot spot.
Use the last sheet “How big are volcanic eruptions” in your packet to decide what it should really be called!
[The major features of the caldera measure about 34 miles (55 km) by 45 miles (72 km)]

22. These are the three main types of volcanoes, in order by their normal average sizes.

23. What is cinder cone, composite, and shield?

24. True or False? Volcanic ash is dense, but fairly light in weight, and easily blown about, like in the movie Dante’s Peak.

25. What is False? Volcanic ash is dense and fairly heavy in weight.
How would the volcanic ash interfere with plane engines, our lungs, and car engines?
Answer is under here
Ash blocks air (oxygen) from getting in

26. Which of the following is not true in all volcanoes
Which of the following is not true in all volcanoes? All volcanoes have magma All volcanoes can have ash All volcanoes have gasses All volcanoes have side vents

27. What is “All volcanoes have side vents?”
Make sure that the other 3 answers are in the middle of your Venn Diagram!

28. True or false? If carbon dioxide gas is being emitted from a volcano through vents, there is a volcanic eruption coming.

29. What is False? Not always an eruption coming if gas is coming out.
Yellowstone vents gases all the time. Still the release of gases may be the start of something! What is a more likely indication of a volcano getting ready to blow up?
Answer is under here
More seismic activity (earthquakes)

30. What are the five ways a volcano can kill you?

31. What is Pyroclastic Flow, Tsunami, Landslide, Lahar, and Gas.
And then you might just ________ to death.
Starve

32. These 5 U.S. states have volcanoes in them

33. Answers vary – use your “Volcanoes in the US” worksheet!

34. Which volcanoes go “pop,” and which do not?

35. Shield = more “gentle” Cinder = small “pop” Stratovolcano = big “pop”

36. This is another name for a stratovolcano

37. Composite Volcano

38. This is the substance that makes volcanoes from continental crust tend to be more explosive than those from oceanic crust:

39. What is silica

40. What is a hole in a volcanic area from which hot smoke and gases escape.

41. What is a Fumerole?

42. Pyroclastic Flow is made of ____,____, and ____.

43. What is flaming hot volcanic gas, ash, and rock?

44. Define Pyro and define clast

45. Pyro: Fire Clast: fragment

46. What is the relationship between a magma chamber, a conduit, and a vent?
Also, define each term.

47. What is the system in which magma comes out of a volcano through vents?
Definitions:
Magma chamber: The chamber in the volcano that holds the magma
Conduit: The channel that the magma travels to the vent in.
Vent: The holes in the sides or top of the volcano that release magma and gasses.

48. T/F Silica increases both the density and the viscosity of magma

49. False – it increases the viscosity (stickiness/thickness) of magma, but not the density (how much mass in in a certain volume of magma)

50. Explain the differences between casts and molds

51. CASTS have the 3-dimensional shape of the original object
CASTS have the 3-dimensional shape of the original object. MOLDS have the outline of the original object and can be filled with material to make a copy of the original object
