  1. 1What does CMBR stand for?
    1. ACosmic microwave background radiation
    2. BCosmological microwave background radiation
    3. CCosmic microwave background radiography
  2. 2What are the three main pieces of evidence for the Big Bang Theory?
    1. AWe can still hear the explosion with special equipment
    2. BWe can detect radiation left over from the big bang (CMBR)
    3. CWe can tell that all distant galaxies are moving away from us because they are red-shifted
    4. DWe can tell that all distant galaxies are moving closer to us because they are red-shifted
    5. EVery distant galaxies move faster away from us than closer ones
  3. 3The light from distant galaxies appears more blue than it should because the waves emitted have a shorter wavelength due to the doppler effect
    1. AVerdadeiro
    2. BFalso
  4. 4How old is the universe estimated to be?
    1. A13.7 thousand years old
    2. B13.7 million years old
    3. C13.7 billion years old
  5. 5The further away a galaxy is from us, the faster it is moving away from us
    1. AVerdadeiro
    2. BFalso
  6. 6According to the Doppler effect, what happens to sound waves emitted at a constant pitch from a car moving towards you?
    1. AThey move more quickly, so their pitch increases
    2. BTheir wavelength increases, so their pitch increases
    3. CTheir frequency increases, so their pitch increases
  7. 7What piece of evidence is only explained using the Big Bang Theory?
    1. ACMBR
    2. BRed shift
  8. 8What do missing wavelengths/black lines on the spectrum of light wavelengths emitted from a star mean?
    1. AThese are the chemical components of dust in space between us and the star absorbing certain light frequencies
    2. BThese are the chemical components of the star absorbing certain light frequencies
    3. CThese form when there are solar flares which interrupt the emission of light from the star
  9. 9All elements absorb the same wavelength of light
    1. AVerdadeiro
    2. BFalso
  10. 10The absorption lines on the Spectra of distant galaxies are shifted ______ relative to the sun
    1. ARed
    2. BBlue
