Depletion of the Ozone Layer * Function and location of the Ozone Layer The ozone layer is a portion of earth’s atmosphere that contains high levels of ozone. Ozone (O3) is a triatomic molecule consisting of three oxygen atoms. It is an allotrope of oxygen. Ozone is formed when oxygen molecules after absorbing ultra violet photon then converts a single O2 into two atomic oxygen radicals. The atomic radicals then combine with separate O2 molecules to create two O3 molecules. The main function

Ozone Danielle Farrar March 16‚ 1997 Triatomic oxygen‚ O3‚ is most commonly known as ozone. It has a resonance structure‚ and can be drawn in two different ways: O=O- O-O=O It is a bluish‚ explosive gas at room temperature‚ and has a boiling point of -119°C. It has a melting point of -193°C‚ and is a blue liquid. It ’s critical temperature and pressure are -12.1°C and 53.8 atm‚ respectively. It has a pleasant odor in concentrations of less than 2 ppm‚ and is irritating and injurious

Ozone depletion describes two distinct but related phenomena observed since the late 1970s: a steady decline of about 4% per decade in the total volume of ozone in Earth’s stratosphere (the ozone layer)‚ and a much larger springtime decrease in stratospheric ozone over Earth’s polar regions. The latter phenomenon is referred to as the ozone hole. In addition to these well-known stratospheric phenomena‚ there are also springtime polar tropospheric ozone depletion events. The details of polar ozone

Ozone As A Disinfectant Joey Finnegan Section 01 October 3‚ 2010 Ozone is a highly reactive gas composed of three oxygen atoms. Ozone is an unstable gas that can destroy bacteria and viruses. Ozone can have many different effects on humans depending on where it is in the atmosphere‚. Some of these effects can be harmful although some can be good. An excess‚ or high concentration of ozone in an inclosed area can be quite harmful to humans although in moderation and if used properly ozone

The ozone layer is an invisible layer of gas that shields us from UV radiation. UV radiation is ultraviolet radiation‚ or rays of the sun that can harm living things. One problem today is that the protective ozone layer around the earth is being destroyed (PROBLEM). (2) PARAGRAPHS 2‚ 3 & 4 (DEVELOPED FROM

Ozone Depletion: An Introduction Planet Earth has its own natural sunscreen that shields us from the sun’s damaging ultraviolet radiation. It’s called the ozone layer: a fragile band of gases beginning 15 kilometres above our planet‚ and reaching up to the 40-kilometre level. Human activities have caused a substantial thinning of this protective covering — not only over the North and South Poles‚ but right over our heads. Stopping ozone layer depletion is one of the major challenges facing the

IMPACTS OF OZONE Introduction Ozone is a gas that occurs naturally in our atmosphere. Most of it is concentrated in the ozone layer[->0]‚ a region located in the stratosphere several miles above the surface of the Earth. Although ozone represents only a small fraction of the gas present in the atmosphere‚ it plays a vital role by shielding humans and other life from harmful ultraviolet light from the Sun. Human activities in the last several decades have produced chemicals‚ such as chlorofluorocarbons

For that reason the atmosphere and the ozone layer within it are crucial to a stable life on this planet. The ozone layer is in danger‚ however. It is facing depletion by a toxic man-made substance called chlorofluorocarbons (CFCs). Together the international community is working through treaties and conventions to stop this environmental problem. To understand the problem behind ozone depletion we first must understand what ozone is and how it works. Ozone is a thin protective layer that starts

The ozone layer protects the Earth from the ultraviolet rays sent down by the sun. If the ozone layer is depleted by human action‚ the effects on the planet could be catastrophic. Ozone is present in the stratosphere. The stratosphere reaches 30 miles above the Earth‚ and at the very top it contains ozone. The suns rays are absorbed by the ozone in the stratosphere and thus do not reach the Earth. | | | | | | The Ozone Layer Over Time. Image Credit: Institute for Studies in Development
