Unformatted text preview: gases and radiated back toward the surface, warming the surface even more. Some of the energy is radiated back toward space. The surface warms enough so that the amount that does leak back out to space balances the solar energy flow inward. Note that if the greenhouse was a perfect blanket, then the surface would continue to get hotter and hotter. The primary greenhouse gases found in the atmospheres of our solar system's planets are given in the figure below. Not shown are chlorofluorocarbons (CFC's) and hydrofluorocarbons (HFC's) that are synthesized by humans. On the Earth the relative amounts these molecules contribute to the total greenhouse effect occurring are approximately: 60% for water, 26% for carbon dioxide, 5% for methane, 4% for ozone, 4% for the CFC's/HFC's, and 2% for nitrous oxide (rounding of the numbers to integer values means they will not add up to exactly 100%)....
