11. Which galaxy is shaped like a hurricane?
spiral

12. This states that the universe started with an explosion and is still expanding outward.
The Big Bang Theory

13. List the 7 major parts of the Electromagnetic Spectrum in order from longest to shortest wavelength.

14. Which type of wave has the highest frequency?
Gamma Rays

15. How do we know the universe is still expanding?
Red shift
As light moves away it pulls light waves farther apart making a larger wavelength like red.

16. If a galaxy has a red shift, what does that tell you about it?
It is moving away from us

17. What type of galaxy is the Milky Way?
spiral

18. Discovered galaxies beyond our own
Hubble

a light year

20. What is the name of the diagram that shows the brightness and temperature of stars?
Hertzsprung-Russell
(H-R)

21. A, C, D - main sequence B- White dwarf E- Red Giant
Label each type of star on this diagram
A, C, D - main sequence
B- White dwarf
E- Red Giant

22. Which star is both bright and relatively cool for a star?
E- Red Giant

23. A or E because they are the largest
Which star or stars is most likely to become a supernova and why?
A or E because they are the largest

24. Expand into red giant like E Left with white dwarf like B
What can we expect to happen to star C during its life cycle?
Expand into red giant like E
Left with white dwarf like B

25. What unit is used to measure the distance between Earth and our nearest star Polaris?

33. A periodic rise and fall of water level in the ocean is called
a tide

34. The dominate force behind the tides is
the moon’s gravity

35. When the moon’s pull is strongest on the part of the Earth facing the moon, water on that side bulges toward the moon creating…
