The various gases present in atmosphere absorb and radiate the sunlight by greenhouse process. Many construction works have been delayed due to adverse weather conditions. These layers reflect medium and high frequency radio waves back to the earth.

The earth’s surface gets heated after receiving heat energy (insolation) from the sun. This is a story of a millionaire Jay Gatsby and his passion for the beautiful Daisy Buchanan. Of the incoming solar radiation nearly 50 per cent is able to reach the earth surface and the rest 50 per cent is reflected back into the space from the atmosphere and from ground. Conduction may be effec­tive only when there is difference in temperatures in different parts of a single body or in two bodies and the process continues till the temperatures of all parts of a body or of two touching bodies become same.
