WebRadiation is the process by which the earth receives heat energy from the sun, about 93 million miles away. This energy is produced in the sun, where the temperature is many million degrees, by nuclear fusion, a process in which hydrogen is converted into helium. In the process, some of the sun's mass is converted to thermal energy. WebUVB is short-wave UV radiation between 280 and 320nm. It can just penetrate the outer protective layer of the skin and is responsible for delayed tanning, sunburns and most skin cancers. A large amount of UVB is absorbed by the ozone layer - only 5% reaches our planet's surface. UVC, with wavelengths between 100 and 280nm, is very energetic. WebThe earth absorbs the incoming radiation from the sun and then re-emits it, acting itself as a blackbody. In order for the sun-earth system to be in equilibrium, the earth must emit the same amount of energy it absorbs (though not necessarily at the same wavelength). curly fleece plush
