Greenhouse+Effect

The greenhouse house effect is a natural occurance that helps regulate the temperature of the planet. When sun's rays heat the Earth, some heat escapes back into space and the rest of the heat is trapped in the atmosphere by clouds and greehouse gases. Heat energy keeps the planet warm; without it, the Earth would be cold and uninhabitable.



Greehouse gases are gases that trap heat in the atmosphere. Some greenhouse gases are naturally emitted through natural processes and human activites. Greehouse gases include:
 * carbon dioxide (emitted from fossil fuels and chemical reactions)
 * methane (emitted from production of coal, natural gas, and oil)
 * nitrous oxide (emitted during agricultural and industrial activites)
 * fluorinated gases (emitted from a variety of industrial processes)
