  • question_answer 17) What would have happened if the greenhouse gases were totally missing in the earth's atmosphere? Discuss.


    The solar energy radiated back from the earth's surface is absorbed by greenhouse gases which re-emit IR-radiations of longer wavelengths. These radiations heat up the atmosphere near the earth's surface and keep it warm. If there were no greenhouse gases, the earth would be a very cold place and there would have been no vegetation and life on the earth.
