The greenhouse effect refers to the warming of the earth's atmosphere because of some greenhouses gases trapping the heat radiated from the earth. The radiated heat is trapped because of the presence of some gases in the atmosphere that does not allow the heat to escape.
So it becomes warmer than it should. Most of these gases such as CFCs are released into the atmosphere by humans. When this happens on a larger scale, then dramatic and irreversible changes occur in the climate, which pose a threat to life.
- Understanding the greenhouse effect helps identify what factors lead to global warming
- It helps identify environmental-friendly alternatives to the heat-trapping gases
- It demonstrates how human activity can make a global impact on weather
Study the greenhouse effect at home
Make a greenhouse- you can make a small model. Use the links provided here to learn how you can build a greenhouse at home. Select appropriate plants best suited for the greenhouse.
Keep two thermometers ready to record the temperature periodically and compare between the temperature outside and inside the greenhouse. Record these temperatures in a chart and compare the results. Note what happens when it is raining outside the greenhouse. By how many degrees does the temperature go up during exceptionally hot days?
Develop a model of the carbon cycle that illustrates the greenhouse effect. Through this model you can show how different gases contribute to the rise in temperature. Identity the greenhouse gases and what factors cause these gases to be released into the atmosphere. Did you know that rice farming also contributes to the greenhouse effect?
Study the impact of the greenhouse effect on human conditions like poverty.
