Expert Solution

Step 1
Greenhouse gases have develops a protective layer surrounding the earth and take infrared radiation. Some of these radiations are reradiated back to the earth surface. This downward flow of radiations is termed greenhouse flux. As a result, the environmental temperature rises up at the surface level. This phenomenon is termed the greenhouse effect. The chief greenhouse gases are carbon dioxide, chlorofluorocarbons, ozone, methane, water vapours etc.
