        • 21%
      • other
        • noble gases
        • Carbon dioxide
        • Water vapour
    • Time Line
      • Volcanoes
        • Released carbon dioxide
          • Like Mars or Venus
        • Oceans
          • Absorbed carbon dioxide
            • Formed carbonates precipitates

      • The Greenhouse Effect
        • Sun emits short wavelength radiation
          • Earth absorbs radiation
          • Radiation reflected back to atmosphere
            • Atmosphere absorbs long wavelength radiation
            • re-radiates energy in all directions
              • Increases Earth temperature
