THE GREENHOUSE EFFECT
The greenhouse effect is responsible for maintaining the temperature of
the Earth.Without any greenhouse effect the average temperature of the Earth
would be about -18˚C, similar to a domestic
freezer. Instead it averages around 15˚C. Many, although not all, gases in the
atmosphere act as so-called ‘greenhouse gases’ and help to warm our
planet. These include: carbon dioxide;
water vapour; methane; chlorofluorocarbons (CFCs) and nitrous oxide.
The diagram below shows the greenhouse
effect. Add labels to the diagram.
