Rough,light colored surface
Solar radiation is the most common type of radiation on earth. The earth also emits thermal radiation from its crust as a result of decaying of uranium.
Solar radiation makes up most of earth's energy.
Ocean
One surface type on Earth that helps absorb solar energy and keeps the planet warm is water. Another surface type that helps keep the planet warm by absorbing solar energy is vegetated land.

Solar radiation is most intense at noon.
Most background radiation comes from natural sources, while most artificial radiation, plants absorb radioactive materials from the soil and these pass up the food chain.
Rough,light colored surface
Ultraviolet radiation
visible
Most of the solar radiation is absorbed when it reaches the surface of the earth. Some of the solar radiation is also absorbed in the atmosphere.
metal
The atmosphere absorbs most of the radiation. The ozone layer absorbs most of the UV rays.
Solar radiation.
All materials will reflect, absorb and transmit (allow to pass through) electromagnetic radiation. This is called the Transmit/Reflect (T/R) ratio and it will vary for a material based on the wavelength of the incident radiation. IR radiation does not transmit through most materials. It is absorbed/reflected. Metalized Mylar has a small transmit/reflect ratio.
UV-C and UV-B, as most of the more energetic wavelengths are gone before the ozone layer. credit goes to ANSWERS
