Question 1 - 10

• 1. Convergent plates are moving towards one
  another or colliding (compression) creates
  mountains
• 2. Divergent plates are moving apart
  (tension) creates rift zones
• 3. Transform plates are sliding horizontally
  past one another (shearing) causes earthquakes

4
Answer 1 10

• What are the types of plate boundaries and the
  types of events or features that can occur at the
  boundary?

5
Question 1 - 20

• A long under-sea mountain chain that forms along
  the floor of the major oceans. This is usually
  where new ocean floor is made due to it being a
  divergent boundary.

6
Answer 1 20

• What is the mid-ocean ridge and at what type of
  boundary does it occur?

7
Question 1 - 30

• The change in shape of the land due to pressure
  being applied. It is NOT always bad because it
  does not always lead to destructive results

8
Answer 1 30

• What is deformation?

9
Question 1 - 40

• The amount of force per unit area that is placed
  on a given area or material.
• Three types are
• Tension, shearing, compression
• When it is applied to rocks, folding and faulting
  takes place. This means the rocks bend or break.

10
Answer 1 40

• What is stress, and what does it cause?

11
Question 1 - 50

• 1. During compression, rocks are pushed together
  (convergent boundary) and form mountains.
• 2. During shearing, rock pushes in different
  horizontal directions (transform boundaries)
  causing a rock to thrust or tear apart. This
  causes earthquakes.
• 3. Tension is stress that occurs when forces act
  to stretch an object (divergent boundaries).
  This can cause sea-floor spreading or rift
  valleys.

12
Answer 1 50

• What are the three different types of stress that
  can occur to the Earth?

13
Question 2 - 10

• Tectonic plate boundaries.

14
Answer 2 10

• Where do earthquakes occur?

15
Question 2 - 20

• When stress is applied to a material and causes
  the material to bend.

16
Answer 2 20

• What is a fold?

17
Question 2 - 30

• When stress is applied to a material and causes
  the material to break.
• They occur with more stress or faster applied
  stress while less stress creates folds.

18
Answer 2 30

• What is a fault?

19
Question 2 - 40

• The strength of an earthquake.
• It is determined by the seismic waves that are
  detected by a seismograph.

20
Answer 2 40

• What is the magnitude of an earthquake and how is
  it determined?

21
Question 2 - 50

• The scale used to measure earthquake magnitude
  (strength).

22
Answer 2 50

• What is the Richter Scale?

23
Question 3 - 10

• Seismic waves wave of energy that travels
  through the earth and away from the earthquakes
  focus in all different directions.
• Body Waves (P-waves and S-waves) and Surface
  waves
• P-waves are primary waves or the first waves sent
  out during an earthquake. They are the fastest.
  They can travel through solids, liquids, and
  gases.
• S-waves are also called shear waves or secondary
  waves. They can travel ONLY through solids.
• Surface waves are the seismic waves that do the
  most damage.

24
Answer 3 10

• What are the three types of seismic waves?

25
Question 3 - 20

• The focus is where the earthquake starts in the
  earths body while the epicenter is directly
  above the focus on the earths crust.

26
Answer 3 20

• What is the difference between the epicenter and
  focus of an earthquake?

27
Question 3 - 30

• 1. Crouch down under a table or something sturdy
  and cover your head.
• 2. If outside, lie face down with your head away
  from buildings, power lines, and trees.
• 3. If in a car, pull over but remain inside.

28
Answer 3 30

• What are ways to protect yourself during an
  earthquake?

29
Question 3 - 40

• Seismologists do not know when or where tectonic
  plates are going to move next.

30
Answer 3 40

• Why can earthquakes not be predicted by
  geologist?

31
Question 3 - 50

• Mostly along tectonic plate boundaries. Many
  along the Pacific plate on the ocean floor. Can
  also occur at hot spots.

32
Answer 3 50

• Where do volcanoes form?

33
Question 4 - 10

• Magma is hot, molten rock that is beneath earths
  surface that is pushed upward due to the pressure
  and change in density of the rock beneath Earths
  surface.

34
Answer 4 10

• Why does magma flow up through rock?

35
Question 4 - 20

• Geothermal Energy

36
Answer 4 20

• What is the source of alternative energy at work
  when ground water is heated by magma?

37
Question 4 - 30

• A major earthquake and volcano zone that extends
  nearly all the way around the edge of the Pacific
  Ocean.

38
Answer 4 30

• What is the Ring of Fire?

39
Question 4 - 40

• Earthquakes and volcanoes are all due to heat
  pressure beneath Earths surface. They are
  created when tectonic plates move. They both
  form new landforms. Energy is associated to both
  occurring.

40
Answer 4 40

• What is the relationship between earthquakes and
  volcanoes?

41
Question 4 - 50

• Divergent Boundary- Stress Tension,
  Result/Landform creates rift zones.
• Transform Boundary- Stress Shearing,
  Result/Landform creates earthquakes.
• Convergent Boundary- Stress Compression,
  Result/Landform creates mountains, volcanos.

42
Answer 4 50

• How does plate movement create stress on rock?

43
Question 5 - 10

• Seismic Waves

44
Answer 5 10

• What are the waves of energy from earthquakes
  that travel through Earth?

45
Question 5 - 20

  near the volcano.

46
Answer 5 20

• What can happen when a volcano is about to erupt?

47
Question 5 - 30

• Seismic waves travel through Earths layers at
  different speeds depending on the ___________ of
  the layer.

48
Answer 5 30

• What is density?

49
Question 5 - 40

50
Answer 5 40

• What is how the intensity of an earthquake
  determined?
