Is the sun involved in the greenhouse gases?
Yes. The greenhouse gases trap the sun's heat.
What is the definition of 'greenhouse effect' that relates to science?
The greenhouse effect is the working of greenhouse gases in the atmosphere that capture and retain the heat of the sun. This has kept the atmosphere warm enough for life for millions of years. The sun's infra-red radiation radiating out from the warmed surface of the earth warms greenhouse gases like carbon dioxide, methane and even water vapor.
What is the natural process where the sun's energy is trapped by the atmosphere to make the Earth warm enough for life?
