What does “The Greenhouse Effect” describe? The effect gasses (Greenhouse Gasses) have in
retaining solar radiation within the Earth’s atmosphere.
Diagram
Which is the most common greenhouse gas in our atmosphere?
H2O - water vapour
Which is the most effective greenhouse gas in our atmosphere?
CH4 - methane
Which greenhouse gas is produced through volcanic outgassing?
CO2 - carbon dioxide
Which greenhouse gasses are produced through burning fossil fuels? CO2, CH4, NO2,
Has the greenhouse effect always been considered problematic? Explain your answer. No. The
retained warmth has permitted life to flourish on Earth. Only recently has CO2 produced from
burning fossil fuels produced the enhanced greenhouse effect resulting in an increasing rate of
global warming.

Greenhouse Effect – Teacher Review
What is positive feedback?
Positive feedback occurs when the initial stimulus is
enhanced/increased by the effect.
Give an example of positive feedback producing the enhanced greenhouse effect.
1. Burning fossil fuel produces CO2.
2. Increased CO2 in the atmosphere increases retention of heat from solar radiation.
3. Increased atmospheric heat causes water vapour levels to increase in the atmosphere.
4. Water vapour is a greenhouse gas which causes the atmosphere to retain even more heat.
What can we do to reduce the enhanced greenhouse effect?
Reduce the use of fossil fuels (etc).
