  • The atmosphere encompass all the gases that swirl around the Earth.
  • The blue colour of the sky is because of dispersion and absorption of the Sun's radiation by molecules in the atmosphere.

If we told you earth has had two atmospheres, would you believe us?

  • Earth has had two atmospheres
    • True
      • Correct. The first was lost when a small planet collided with Earth to form the Moon. The second atmosphere was outgased from the interior of Earth. It was retained by gravity and protected from solar winds by the Earth’s magnetic field.
    • False
      • Incorrect. Had to believe right? Try again and learn why the earth has had two atmospheres.
