Venus too hot, Mars too cold…earth just right!. Earth Diurnal Temp Range 10 o C to 20 o C Moon Diurnal Temp Range -150 o C to 120 o C Why the difference? The ATMOSPHERE acts as an insulating layer. What would happen if they didn’t balance?.

What would happen if they didn’t balance? Heat absorbed from Sun balances Heat Radiated from Earth
Earth’s energy spectrum Low Energy High Energy
EMR/light Energy comes from the sun Which radiates long wave Warms up the earth
Carbon Dioxide Methane Water Vapour
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
EMR/light Energy comes from the sun Extra greenhouse gas increases the greenhouse effect making warmer Which radiates long wave Warms up the earth
