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

But there is a significant pending problem in the ozone layer. Each year‚ a large hole appears in it. It is not an actual hole‚ like a hole in a pocket‚ but a thinning in the layer that shows up on satellite pictures. The "hole" is located over Antarctica. It covers an area about the size of the United States. Experiments done in Antarctica show that the hole in the ozone layer appears to let in twice as much ultraviolet radiation as normal‚ according to measurements researchers made there only

OZONE LAYER DEPLETION AND GLOBAL WARMING OZONE LAYER DEPLETION AND GLOBAL WARMING. The ozone layer acts as a giant sunshade‚ protecting plants and animals from much of the sun’s harmful ultraviolet radiations. Ozone forms a layer in the stratosphere‚ 15-40 km above the earth surface. If the ozone in the atmosphere from the ground level to a height of 60 km could be assembled at the earth’s surface‚ it would comprise a layer of gas only about 3mm thick. Global stratospheric ozone

OZONE-LAYER DEPLETION AND NATURAL RESOURCES INTRODUCTION Sometime ago‚ a warning endorsed by more than 1‚600 of the world’s most distinguished scientists‚ including 102 Nobel Prize winner states in part: Human being and the natural world are on collision course. Human activities inflict harsh and often irreversible damaged on the environment and critical resources. If not checked‚ many of our current practices put as serious risk the future that we wish for human society and the plant

The environment is affected by the deposition in the ozone layer.It is directly affecting the environment‚ because the environment is being negatively impacted‚ because of the depletion in the ozone. This depletion was created‚ because of all the CFC that is being released by all the factories and other machines that pollute the air. The UVB radiation affects the physiological and developmental processes of plants. Even though there is the existence of various machines and methods to reduce or repair
Premium Pollution Oxygen Global warming
The depletion of the ozone layer is a major concern today. The ozone layer protects us from the harmful rays of the sun; therefore it is imperative that we preserve it. Since more pollutants are produced today than ever before (because of the major increase in the population)‚ there is a major concern that we create less pollutants to help conserve the ozone layer. In this research paper I will give vital information on how pollution affects the ozone layer and methods instituted to help the ozone

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

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
