Detailed explanation-1: -Minimum values occur at the poles. This pattern is primarily the result of Earth-Sun geometric relationships and its effect on the duration and intensity of solar radiation received.
Detailed explanation-2: -About 40 per cent of the solar radiation received at the earth’s surface on clear days is visible radiation within the spectral range 0.4 to 0.7 m, while 51 per cent is infrared radiation in the spectral region 0.7 to 4 m. The total radiation emitted by the sun in unit time remains practically constant.
Detailed explanation-3: -Answer and Explanation: The specific areas of the planet which receive more intense solar radiation, are the areas that fall under the equator. The equator is an imaginary line that creates two exactly equal hemispheres of the planet: the south and north hemispheres.
