Presentation Transcript

  1. Venus too hot, Mars too cold…earth just right! Earth Diurnal Temp Range 10oC to 20oC Moon Diurnal Temp Range -150oC to 120oC Why the difference? The ATMOSPHERE acts as an insulating layer

  2. What would happen if they didn’t balance? Heat absorbed from Sun balances Heat Radiated from Earth

  3. Earth’s energy spectrum Low Energy High Energy

  4. EMR/light Energy comes from the sun Which radiates long wave Warms up the earth

  5. Carbon Dioxide Methane Water Vapour

  6. EMR/light Energy comes from the sun Normal greenhouse effect makes it warm enough for life on earth Which radiates heat Warms up the earth

  7. EMR/light Energy comes from the sun Extra greenhouse gas increases the greenhouse effect making warmer Which radiates long wave Warms up the earth
