When water evaporates, it takes up heat (cooling the local environment). When water vapor condenses, it releases latent heat, heating up the local environment, usually the air. See more at: http://sxxz.blogspot.com/2010/09/latent-heat-sweat- storms-and-cooling.html#sthash.qQ59mhEq.dpuf
Evaporation is used to cool the bodies of many animals. Sweat evaporating from the skin makes it possible for us to deal with hot weather. On a hot day in dry weather, a person can lose more than a liter of water by evaporation of sweat. Think of the amount of heat it would take to boil away a liter of water. http://sxxz.blogspot.com/2010/09/latent-heat-sweat-storms-and- cooling.html#sthash.qQ59mhEq.dpuf

Electromagnetic Spectrum UV Light is one form of energy the Earth receives from the sun. UV has a shorter wavelength than visible, and is energetic enough to cause sun burns, skin cancer and other problems. http://www.badgerbalm.com/uploads/images/electromangetic-spectrum-uv.JPG
UVC, the ultraviolet light with the shortest wavelength is completely removed by ozone. Most of UVB (the second most energetic) is absorbed. http://www.acs.org/content/acs/en/education/resources/highschool/chemmatters/past-issues/archive-2012-2013/ozone-layer-our-global- sunscreen/_jcr_content/mainContent/columnsbootstrap/column0/textimage_0/image.img.jpg/1368218980203.jpg

Ozone constantly forms and breaks down in the stratosphere as it absorbs UV http://forces.si.edu/atmosphere/images/media/library_021_lg.jpg

Light from the sun contains all wavelengths of the visible spectrum. Wavelengths can be absorbed, reflected, or scattered.
The sky appears blue because blue light is scattered by gases in the air. http://www.sciencemadesimple.com/img_sky/bluesky.jpg
Some clouds appear white because the tiny droplets of water or ice crystals scatter all wavelengths of light. All the wavelengths combined (red, orange, yellow, green, blue, indigo and violet) create white light.
Some clouds appear dark because they are too thick to allow all light to pass through.
Rainbows are visible when water droplets refract light. Each wavelength (color) is bent (refracted) a different amount. http://2.bp.blogspot.com/-XkfkdAUCUb8/UhCDygujEjI/AAAAAAAAFXM/cEzv5tpDY7Y/s1600/pelangi-kehidupan.jpg
