Quiz on galaxies and space. Test on Tuesday September 28th

Resource summary

Question 1

Question
What did Edwin Hubble do?
Answer
  • Identify other galaxies, invented the first telescope and realize that galaxies were moving away from us.
  • invent the telescope and be an astronomer.
  • a famous baker and invented the raisin theory.
  • All of the above.

Question 2

Question
Galaxies are moving away from us.
Answer
  • True
  • False

Question 3

Question
Hubble believed that the universe is [blank_start]expanding[blank_end] in all directions.
Answer
  • expanding

Question 4

Question
What is electromagnetic radiation?
Answer
  • Energy carried in the form of waves.
  • Rays from the sun.
  • Used in X-Rays.
  • Used to make food.

Question 5

Question
What does a spectroscope do?
Answer
  • Acts like a prism.
  • Separates light into basic component colours.
  • Allows the user to view spectral lines.
  • All of the above.

Question 6

Question
A spectroscope measures wave lengths from the stars spectral lines?
Answer
  • True
  • False

Question 7

Question
When Edwin Hubble was studying the universe he saw the spectral lines from the purple side of the spectrum.
Answer
  • True
  • False

Question 8

Question
[blank_start]Red shift[blank_end] is when lights [blank_start]wave lengths[blank_end] become [blank_start]longer[blank_end]. That means that the object is [blank_start]receding[blank_end] away from us. Meaning that distant [blank_start]galaxies[blank_end] are moving [blank_start]away[blank_end] from us. When Edwin Hubble saw this, he discovered that the Universe was [blank_start]expanding[blank_end]. [blank_start]Cosmological Red shift[blank_end] is when lights wavelengths are constantly being lengthened. This is the main theory for how the Universe was born.
Answer
  • Red shift
  • wave lengths
  • longer
  • receding
  • galaxies
  • away
  • expanding
  • Cosmological Red shift

Question 9

Question
What is the Big Bang theory?
Answer
  • A show.
  • When space itself began, from a really tiny piece of space suddenly expanded into immense size in a very short time.
  • When all the planets were formed.
  • None of the above.

Question 10

Question
Cosmic background radiation is:
Answer
  • Radiation from microwaves.
  • A type of wavelength.
  • noise in space.
  • radiation left over from the Big Bang. When the universe was created it produced heat in the form of microwave radiation.

Question 11

Question
COBE stands for: Cosmic Background Explorer.
Answer
  • True
  • False

Question 12

Question
One of the strongest pieces of evidence to support the big bang theory is [blank_start]Cosmic Background Explorer[blank_end]. A team of Scientists moped the universe by using a satellite they sent up into space. they mapped the [blank_start]background radiation[blank_end]. Red areas indicate hotter places. Blue areas indicate places that have had time to cool.
Answer
  • background radiation
  • Microwave radiation
  • UV radiation
  • Wavelengths
  • Cosmic Background Explorer
  • WMAP
  • Edwin Hubble
  • NASA

Question 13

Question
Wilkinson Microwave Antistropy Probe was sent up into space to make better predictions then the COBE.
Answer
  • True
  • False

Question 14

Question
Galaxies are clouds made out of dust and gas.
Answer
  • True
  • False

Question 15

Question
There are three types of galaxies: [blank_start]Spiral[blank_end], [blank_start]Elliptical[blank_end] and [blank_start]Irregular[blank_end]. Spiral Galxies are shaped like a pin wheel from above and from the side it looks like a plate with an orange in it. it contains mostly [blank_start]new[blank_end] [blank_start]stars[blank_end].
Answer
  • Spiral
  • Elliptical
  • Irregular
  • new
  • stars
