Sue's Rays

:On an average. the temperature decreases from the equator to the poles. This is because as we go nearer the poles the sun's raye fall more obliquely on the earth's surface. As Peking has a latitude of 40°N and Hong Kong 22°N, and Feking is nearer the pole than H.K., therefore on an average it is cooler in Peking than in: Hong Kong.

Suppose K and Y are two bundles of the suns of squal thickness, i.e. with the same heating atriking Peking and Hong Kong at the same time, The. sun's raya Y fall more obliquely on the earth's surface than the sun's rays X Now the bundle of rays x has to

the Bur heat the

the shaded area of Peking. But the area of Hongkong' Le much smaller than the area of Peking and since the heat applied is the same in both cases, it follows that

Lee of Hong Kong must be hotter than the area of Peking!!

Again une bundle of rays, because of its obliquity has a longer passage through the atmosphere than the raya X, Thus more of the energy of the sun's rays will be absorbed by particles of moisture and dust etc, so that when the sun's rays Y. ultimately; reach the earth thay, will have been deprived of more of their heating power of the sun. Therefore on ag average it is cooler: in Peking than in Hong Kong."
