Read each question carefully and answer to the best of your ability. Refer to the provided diagram where applicable.
Observe the diagram below illustrating the greenhouse effect.
1. Which of the following is NOT a primary greenhouse gas?
Carbon Dioxide (CO2)
Methane (CH4)
Nitrogen (N2)
Water Vapor (H2O)
2. The enhanced greenhouse effect is primarily caused by:
Increased volcanic activity
Human activities releasing greenhouse gases
Changes in Earth's orbit
Natural fluctuations in solar radiation
3. The greenhouse effect is a natural process that warms the Earth's .
4. Greenhouse gases absorb and re-emit radiation, trapping heat in the atmosphere.
5. Without the greenhouse effect, Earth's average temperature would be much colder.
True
False
6. Deforestation contributes to the greenhouse effect by reducing the amount of carbon dioxide absorbed from the atmosphere.
True
False
7. Briefly explain the difference between the 'natural greenhouse effect' and the 'enhanced greenhouse effect'.
8. Describe two potential consequences of an enhanced greenhouse effect on global climate patterns.
