On a bright‚ cool day‚ most people perceive the sun’s rays as feeling good on their skin. By nature‚ many of us even make an effort to stay out in the sun to bronze our bodies. The sun is 93 million miles away from the Earth and its energy travels to us in moving waves called radiation. That energy takes the form of heat‚ light‚ and other energy as well. Visible sunlight allows us to see the world around us. But there is invisible sunlight as well. These rays can not be seen. Some can be
Premium Sun Ultraviolet Ozone layer
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
Premium Ozone depletion Sun Ozone layer
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

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

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 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

Conservation of Ozone in Hong Kong The ozone layer present in the stratosphere of the Earth is utmost important to us as it protects us from the exposure of ultraviolet rays which leads to several harmful effects. Without the ozone layer‚ human will be more prone to skin cancer and eye cataracts. Ultraviolet rays can also cause harm to marine life by reducing the amount of planktons and consequently depreciates the amount of fishes in the ocean. Besides that‚ the depletion of the ozone layer disrupts

• Depletion of ozone and formation of ozone hole • Ozone‚ in fact is a gas having fishy smell and O3 molecules which works as the protective shield for the life in the earth. It absorbs solar ultraviolet radiations and thereby protects life on the earth from several damage such as DNA mutation‚ skin cancer‚ blood cancer‚ etc. In the year 1985‚ NASA detected the thinning out of the ozone layer leading to the formation of ‘ozone hole’ in Antarctica. Since then the scientists have been regularly
