ROLE OF YOUTH IN OZONE LAYER PROTECTION Ozone layer plays a vital role in protecting animals‚ human beings and plants from ultraviolet radiation. Ozone layer is destroyed by a group of manufactured or human made chemicals such as chlorine bromine. These chemicals are called "ozone-depleting substances". Ozone layer is destroyed by some natural’s ways and some humane made activities. A single molecule of chlorine can break apart thousands of molecules of ozone. Chlorofluorocarbons the most widely

protects us from the full blast of the sun’s radiation. Way up in the part of the atmosphere‚ called the stratosphere‚ a layer of gas filters out most of the sun’s damaging ultraviolet rays. This layer of gas is called ozone and is located about five miles to 25 miles above the surface of the Earth. (Bright‚ 1991). Only about one-millionth of our atmosphere is made up of ozone. But it has a tremendously important job. Ozonecan absorb‚ or soak up‚ the part of sunlight called ultraviolet radiation
Premium Sun Ultraviolet Ozone layer
The ozone layer is a layer in Earth’s atmosphere which contains relatively high concentrations of ozone (O3). This layer absorbs 97–99% of the Sun’s high frequency ultraviolet light‚ which is potentially damaging to the life forms on Earth.[1] It is mainly located in the lower portion of the stratosphere The ozone layer was discovered in 1913 by the French physicists Charles Fabry and Henri Buisson The photochemical mechanisms that give rise to the ozone layer were discovered by the British physicist

OZONE LAYER The Earth ’s ozone layer protects all life from the sun ’s harmful radiation‚ but human activities have damaged this shield. Less protection from ultraviolet light will‚ over time‚ lead to higher skin cancer and cataract rates and crop damage. The ozone layer is one layer of the stratosphere‚ the second layer of the Earth’s atmosphere. The stratosphere is the mass of protective gases clinging to our planet. Ozone is only a trace gas in the atmosphere only about 3 molecules for every
Premium Ozone depletion Oxygen Ozone
Ozone‚ pronounced OH-Zohn‚ is a form of oxygen that is present in the earth’s atmosphere in small amounts. Ozone in the upper atmosphere is a major factor in making life on earth possible. But ozone in the lower atmosphere contributes to air pollution. Society has been widely addressed with the many problems that we are having in our environment today. A major problem is that of CFCs. CFC stands for Chlorofluorocarbons which are found in many of the aerosol spray cans. In December of

The Ozone Layer It acts as a sun block and filters out the dangerous ultra-violet rays from the sun ("The Chemistry of the Ozone Layer"). The Earth ’s atmosphere is broken up into two layers that have to do with ozone ("Ozone Layer"). The troposphere is the lowest layer ("Ozone Layer"). It extends from Earth ’s surface up to about ten kilometers in altitude ("Ozone Layer"). All most all human activities happen in this layer ("Ozone Layer"). The next layer is the stratosphere ("Ozone Layer")
Premium Ozone depletion
The ozone layer is a layer in Earth’s atmosphere which absorbs most of the Sun’s UV radiation. It contains relatively high concentrations of ozone (O3)‚ although it is still very small with regard to ordinary oxygen‚ and is less than ten parts per million‚ the average ozone concentration in Earth’s atmosphere being only about 0.6 parts per million. The ozone layer is mainly found in the lower portion of the stratosphere from approximately 20 to 30 kilometres (12 to 19 mi) above Earth‚ though the
Premium Ozone depletion Ozone Ultraviolet
The ozone layer is a deep layer in the stratosphere‚ encircling the Earth‚ that has large amounts of ozone in it. The layer shields the entire Earth from much of the harmful ultraviolet radiation that comes from the sun. Interestingly‚ it is also this ultraviolet radiation that forms the ozone in the first place. Ozone is a special form of oxygen‚ made up of three oxygen atoms rather than the usual two oxygen atoms. It usually forms when some type of radiation or electrical discharge separates

ISSN: 2010-0264 Ozone Layer Depletion and Its Effects: A Review Sivasakthivel.T and K.K.Siva Kumar Reddy Abstract - There are many situations where human activities have significant effects on the environment. Ozone layer damage is one of them. The objective of this paper is to review the origin‚ causes‚ mechanisms and bio effects of ozone layer depletion as well as the protective measures of this vanishing layer. The chlorofluorocarbon and the halons are potent ozone depletors. One of
