Cosmology GCSE (AQA specifications)

Question 1 of 10

Medal-premium 1

What does CMBR stand for?

Select one of the following:

  • Cosmic microwave background radiation

  • Cosmological microwave background radiation

  • Cosmic microwave background radiography

Question 2 of 10

Medal-premium 1

What are the three main pieces of evidence for the Big Bang Theory?

Select one or more of the following:

  • We can still hear the explosion with special equipment

  • We can detect radiation left over from the big bang (CMBR)

  • We can tell that all distant galaxies are moving away from us because they are red-shifted

  • We can tell that all distant galaxies are moving closer to us because they are red-shifted

  • Very distant galaxies move faster away from us than closer ones

Question 3 of 10

Medal-premium 1

The light from distant galaxies appears more blue than it should because the waves emitted have a shorter wavelength due to the doppler effect

Select one of the following:

  • True
  • False

Question 4 of 10

Medal-premium 1

How old is the universe estimated to be?

Select one of the following:

  • 13.7 thousand years old

  • 13.7 million years old

  • 13.7 billion years old

Question 5 of 10

Medal-premium 1

The further away a galaxy is from us, the faster it is moving away from us

Select one of the following:

  • True
  • False

Question 6 of 10

Medal-premium 1

According to the Doppler effect, what happens to sound waves emitted at a constant pitch from a car moving towards you?

Select one of the following:

  • They move more quickly, so their pitch increases

  • Their wavelength increases, so their pitch increases

  • Their frequency increases, so their pitch increases

Question 7 of 10

Medal-premium 1

What piece of evidence is only explained using the Big Bang Theory?

Select one of the following:

  • CMBR

  • Red shift

Question 8 of 10

Medal-premium 1

What do missing wavelengths/black lines on the spectrum of light wavelengths emitted from a star mean?

Select one of the following:

  • These are the chemical components of dust in space between us and the star absorbing certain light frequencies

  • These are the chemical components of the star absorbing certain light frequencies

  • These form when there are solar flares which interrupt the emission of light from the star

Question 9 of 10

Medal-premium 1

All elements absorb the same wavelength of light

Select one of the following:

  • True
  • False

Question 10 of 10

Medal-premium 1

Select one of the following:

  • Red

  • Blue
