Radiation
Electromagnetic radiation
there are three types of heat transfers: conduction, convection, and radiation. Heat transfer through space requires radiation, which involves the electromagnetic waves: gamma ray, x-ray, ultraviolet, visible, infrared, microwave & radiowave.
The Sun's energy is transmitted by electromagnetic radiation, with most of the heat caused by ultraviolet radiation striking the Earth's surface. This heat is re-radiated by infrared radiation.
They travels in the form of waves and are filtered through the Earth's atmosphere.
Waves of heat and light, called radiation, travel to earth.
through radiation
The sun moves through the electromagnetic waves. Conduction and Convection transfers energy between differences in density.

The ultraviolet region begins at the short wavelength (violet) limit of visibility and extends to the wavelength of long x-rays. It is loosely divided into the near (400-300 nm), far (300-200 nm), and extreme (below 200 nm) http://www.answers.com/topic/ultraviolet regions (see illustration). In the extreme ultraviolet, strong absorption of the radiation by air requires the use of evacuated apparatus; hence this region is called the vacuum ultraviolet. Important phenomena associated with ultraviolet radiation include biological effects and applications, the generation of http://www.answers.com/topic/fluorescence, and chemical analysis through characteristic absorption or fluorescence.
