The greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases, and is re-radiated in all directions. Certain gases in the atmosphere retain part of the thermal radiation emitted by the Earth's surface after being heated by the sun, this maintains the planet's temperature at a level suitable for the development of life. Carbon dioxide, methane, and water vapour are the most important greenhouse gases. This week in class, we’re reading "Explainer: Global warming and the greenhouse effect" by Agnieszka Biskup.In the informational text “Explainer: Global warming and the greenhouse effect,” Agnieszka Biskup explains the greenhouse effect and why the Earth is warming. 3.

These heat-trapping gases are called greenhouse gases. The greenhouse effect is an ecosystem service which warms the Earth to temperatures which support life. This is how global warming happens. Small changes in the atmospheric concentration of these gases can lead to changes in temperature that make the difference between ice ages when mastodons roamed the Earth, and the sweltering heat in which the dinosaurs lived. b. Why does the image of the scientist fade after carbon dioxide has been turned on? The "Greenhouse Gases" students should then each trap one "Heat" student. 3.

The greenhouse effect is a natural phenomenon, but the extra gases produced by human activity are making it stronger. Without the greenhouse effect, Earth would be too cold for life to exist. The greenhouse effect is a warming of Earth’s surface and the air above it. 4. Since there are many more Greenhouse Gases, more "Heat" will be trapped on Earth, with very little, if any, "Heat" escaping. But first the role of greenhouse gases in the atmosphere must be explained. The planet's average surface temperature has risen about 2.12 degrees Fahrenheit (1.18 degrees Celsius) since the late 19th century, a change driven largely by increased carbon dioxide emissions into the atmosphere and other human activities. a. Objective: Introduce "Global Warming" and "The Greenhouse Effect" to students.
