13
Question 2 - 10

• If you have two objects and they increase in
  size, is the force of going to increase or
  decrease?

14
Answer 2 10

• increase

15
Question 2 - 20

• What is the formula used to calculate velocity?

16
Answer 2 20

• Velocity distance/time and include the direction

17
Question 2 - 30

• What is Newtons 3rd law of motion

18
Answer 2 30

• For every action there is an equal and opposite
  reaction

19
Question 2 - 40

• What is true of the acceleration of ALL objects
  near earths surface?

20
Answer 2 40

• ALL objects accelerate at the same speed
  regardless of their size or weight (they all
  accelerate at 9.8 m/s2)

21
Question 2 - 50

• Describe how mass is related to inertia

22
Answer 2 50

• Objects with a larger mass have greater inertia
  (are harder to stop and start) objects with a
  smaller mass have less inertia(are easier to stop
  and start)

23
Question 3 - 10

• The highest part of a wave is called the
  _____________.

24
Answer 3 10

• crest

25
Question 3 - 20

• Half of the distance from crest to trough is
  called ________________.

26
Answer 3 20

• amplitude

27
Question 3 - 30

• What type of wave requires a medium?

28
Answer 3 30

• Mechanical wave

29
Question 3 - 40

• What type of wave moves perpendicular to the
  movement of the medium

30
Answer 3 40

• Transverse wave

31
Question 3 - 50

• What is the difference between constructive and
  destructive interference

32
Answer 3 50

• Constructive-two waves that combine to form a
  wave that is bigger than either original
• Destructive-two waves that combine to form a wave
  that is smaller than either original

33
Question 4 - 10

• What is a positive and a negative of nonrenewable
  resources?

34
Answer 4 10

• Positive they are cheap and abundant(common)
• Negative they are bad for the environment and we
  will run out of them eventually

35
Question 4 - 20

• What type of plate boundary has plates coming
  together AND one plate moves underneath the
  other?

36
Answer 4 20

• Subduction ( a type of convergent boundary)

37
Question 4 - 30

• Describe what conduction is

38
Answer 4 30

• Energy transfer through object that are in
  contact

39
Question 4 - 40

• How does convection impact the formation of the
  Earth?

40
Answer 4 40

• Convection currents in the mantle cause hotter
  particles to rise pushing tectonic plates around
  the surface of earth

41
Question 4 - 50

• Describe three ways that water can be polluted.
  Your examples should each be in a different part
  of the water cycle.

42
Answer 4 50

• Car/factor emissions-in the air during
  evaportation
• Pesticides-in groundwater
• Oil spill-in surface waters
• Acid rain-during precipitation

43
Question 5 - 10

• how do all stars begin their lives

44
Answer 5 10

• As a nebula (cloud of dust)

45
Question 5 - 20

• How do small and medium mass stars end their
  lives?

46
Answer 5 20

• As black dwarfs

47
Question 5 - 30

• Describe what the big bang theory is

48
Answer 5 30

• The theory that the universe began as a tiny,
  compact ball and expanded outward to create the
  universe that is exists and is continuing to
  expand outward today

49
Question 5 - 40

• Describe how stars create energy/light

50
Answer 5 40

• Nuclear fusion caused by the combination of
  hydrogen into helium and the extra energy being
  emitted as light

51
Question 5 - 50

• After nuclear fusion occurs in the core what two
  zones does the light energy transfer through, AND
  describe how the energy is transferred in each
  zone

52
Answer 5 50

• Radiative zone-energy is transferred through
  radiation between individual atoms
• Convection-hotter less dense gas rises to the top
  and the cooler dense gas sinks towards the center
  (convection)
