Nettet25. jan. 2013 · The Earth's atmosphere has four primary layers: the troposphere, stratosphere, mesosphere, and thermosphere. These layers protect our planet by absorbing harmful radiation. Thermosphere … NettetThe ozone layer (which absorbs from about 200 nm to 310 nm with a maximal absorption at about 250 nm)[7]is very effective at screening out UV-B; for radiation with a wavelength of 290 nm, the intensity at the top …

NettetTogether, ozone and oxygen molecules are able to absorb 95 to 99.9% of the ultraviolet radiation that gets to our planet. When UV light is absorbed by oxygen and ozone, heat … NettetStratospheric Oxygen and Ozone molecules absorb 97-99% of the sun's high freguency Ultraviolet light, light with wavelengths between 150 and 300nm. Ultraviolet-B (UV-B) is a section of the UV spectrum, with wavelengths between 270 and 320nm. The amount of UV-B light recieved by a location is strongly dependent on:

NettetIn addition, the amount of atmosphere crossed by sunlight is greater at oblique angles than when the sun is directly overhead. Thus, the light travels through more ozone before reaching the Earth’s surface, …
