Mountain and Volcano Quiz Prep
2
  • SOME STUDY IS HIGHLY RECOMMENDED BY
    THE MANAGEMENT

3
What Type of Volcano?
4
  • Cinder Cone

5
  • What are cinder cones made of?

6
  • Loose bubbly light weight chunks of rocks
  • Rubble

7
  • Why are cinder cones not steeper?

8
  • Cinder Cones have moderately sloping sides
    because loose rubble doesnt stack well.

9
What Type of Volcano?
10
  • Shield

11
  • Why are shield volcanoes not steeper?

12
  • The lava shield volcanoes are made of is very
    thin and travels long distances before it hardens.

13
What Type of Volcano?
14
Composite
15
  • Why are composite volcanoes named composite?

16
They are composed of many different types of
layers
17
  • What is the tallest type of mountain on Earth?

18
  • A shield Volcano named Mona Loa in the Hawaiian
    Islands.

19
  • Which type of volcano is most likely to blow up?

20
  • Composite

21
  • Why do Composite volcanoes tend to blow up?

22
  • They are very weak because many of their layers
    are nothing but ash or cinder. When too much
    pressure builds up, they blow their layers apart.

23
  • Which type of volcano makes a lot of noise and
    fireworks, but isnt too likely to explode?

24
  • Cinder Cone

25
  • What caused the Hawaiian Islands to form?

26
  • Hot spots

27
  • Why are there so many islands?

28
  • The Earths crust is moving, but the hot spot is
    not. Consequently, new volcanoes form over the
    hot spot after the old ones move away.

29
  • What type of volcano is found at Yellowstone?

30
  • A Supervolcano

31
  • Why did they have a hard time locating the
    Yellowstone Volcano?

32
  • It is so big that you have to be in space to see
    the whole caldera.

33
  • Where can we find some composite volcanoes in the
    USA?

34
  • Along the Pacific coast in Washington and Oregon.

35
  • What caused these coastal volcanoes to form?

36
  • The Cascade range was formed by a subduction zone
    where the oceanic plate is sliding under the
    continental plate.

37
  • What are island arc volcanoes caused by?

38
  • Island arc volcanoes are caused by the
    convergence of 2 oceanic plates

39
  • What does ISOSTASY refer to?

40
  • The balance of the weight of a mountain against
    the buoyancy of its base which is submerged in
    the Earths mantle

41
  • The Appalachian Mountains are what type of
    mountains?

42
  • Folded Mountains

43
  • Where are the Appalachian Mountains?

44
  • They run from Georgia to Maine parallel to the
    Atlantic Coast

45
  • What caused the Appalachian Mountains to form?

46
  • They formed by continental/continental
    convergence when North America crashed into
    Africa.

47
  • Why does Oceanic/Continental convergence usually
    only volcanoes while Continental/Continental
    convergence causes a few volcanoes AND folded
    mountains?

48
  • Because oceanic crust forms a continuous
    subduction zone and almost no collision while
    continental collisions only form a limited
    subduction zone, as they make a great big crash

49
  • What causes peaks and valleys in folded
    mountains?

50
  • The softer layers of uplifted rock wear away
    quicker than the harder layers

51
  • What is an uplifted mountain?

52
  • A mountain that was formed by being pushed upward
    by currents in the Earths mantle.

53
  • Where can you find uplifted mountains?

54
  • The closest ones are the Adirondacks in New York
    State.

55
  • Why are the Adirondack mountains not in long
    chains like the Appalachian mountains?

56
  • The Adirondacks were uplifted while the long
    folds of the Appalachians were caused by a
    collision of the whole coast of the continent.

57
  • What causes a fault block mountain?

58
  • Fault block mountains are caused by a continental
    plate that is trying to split apart. The mantle
    pushes it up and spreads it. As the 2 sides pull
    apart, huge blocks of rock drop along the fault
    lines, leaving mountains on one side of the fault.

59
  • Where in the US can we find fault block mountains?

60
  • The Grand Tetons in Wyoming
