Ozone layer, also called ozonosphere, region of the upper atmosphere, between roughly 15 and 35 km (9 and 22 miles) above earth’s surface, containing relatively high concentrations of ozone molecules (o 3) approximately 90 percent of the atmosphere’s ozone occurs in the stratosphere, the region. To understand the problem of ozone depletion, we first need to understand where the ozone layer is and what it does the ozone layer is present in the highest layer of the earth's atmosphere. These events were a result of unusually low temperatures in the stratosphere, increasing the rate of ozone depletion caused by ozone consuming chemicals consequently, it appears that ozone losses may be more severe than scientists originally anticipated. In a cooler stratosphere, ozone loss creates a cooling effect that results in further ozone depletion uv radiation releases heat into the stratosphere when it reacts with ozone with less ozone there is less heat released, amplifying the cooling in the lower stratosphere, and enhancing the formation of ozone-depleting polar stratospheric. The problem of ozone depletion and its adverse consequences have threatened the existence of life on the planet the roll of ozone is very crucial and significant because it acts as a protective shield in the biosphere eco-system against their exposure to deadly and dangerous ultraviolet radiation.
The problem of ozone layer depletion became prominent in the 1980s scientific measurements began to show significant global decreases in ozone some of the general results follow. The effects of ozone depletion on your skin and eyes there are many complicated implications of climate change, but one consequence that has been indisputably measured is the depletion of the ozone layer : the part of the atmosphere that protects us from cosmic radiation. Ozone layer depletion study guide by radhikareddy includes 77 questions covering vocabulary, terms and more quizlet flashcards, activities and games help you improve your grades.
Ozone is a natural gas and is naturally replenished over time this means if we can do something to balance the natural production with its depletion, there should not be a problem unfortunately, it does not quiet work like that. The ozone layer is a deep blanket in the stratosphere made up of comparatively high concentration of the ozone as a result of its chemical composition, ozone is regarded as a special type of oxygen as it contains three oxygen molecules (o3) as opposed to the usual two oxygen molecules (o2. Depletion of ozone layer causes temperature to increase ozone layer blocks about 97% of the the total received by the earth ozone depletion will expose earth to harmful radiations and will burn the life. Some of the major environmental problems are as follows: 1 ozone depletion, greenhouse effect and global warming 2 desertification 3 deforestation 4 loss of biodiversity 5 disposal of wastes 1 ozone depletion, greenhouse effect and global warming: all the three physical phenomena are related.
Also, from direct measurements over antarctica, a column ozone level of less than 220 dobson units is a result of the ozone loss from chlorine and bromine compounds 23 october 2018 the latest false-color view of total ozone over the antarctic pole. Global warming and ozone depletion are not the same problem so thinning results from a reduction in 1 and/or 2, an increase in any of 3 thru 6, or 7 ozone bleeding out into other spaces (seen adjacent to the ozone hole) below is a link that talks about cfc chemistry, about halfway down the page. The ozone layer is the common term for the high concentration of ozone that is found in the stratosphere between 15 and 30km above the earth’s surface it covers the entire planet and protects life on earth by absorbing harmful ultraviolet-b (uv-b) radiation from the sun. Atmospheric levels of ozone-depleting substances (ods odsa compound that contributes to stratospheric ozone depletionods include chlorofluorocarbons (cfcs), hydrochlorofluorocarbons (hcfcs), halons, methyl bromide, carbon tetrachloride, hydrobromofluorocarbons, chlorobromomethane, and methyl chloroform.
Depletion of the ozone layer: its causes, effects, and possible solutions (2004, july 22) it causes health problems like cancer, emphysema, and asthma it also causes the depletion of the ozone layer which results in global warming and melting of the ice caps up until the industrial era, the 2 pages 171 mar/1997 40. The ozone layer is a belt of the naturally occurring gas ozone it sits 93 to 186 miles (15 to 30 kilometers) above earth, and serves as a shield from the harmful ultraviolet b (uvb) radiation. Ozone layer depletion is one of the most serious problems faced by our planet earth it is also one of the prime reasons which are leading to global warming ozone is a colourless gas which is found in the stratosphere of our upper atmosphere. Like global warming, depletion of the ozone layer raises complex problems of cause and effect that have led to international disagreements over coordinated efforts to reverse the problem.
In short, the depletion of the ozone layer results in an imbalanced ecosystem » cfc is an organic compound primarily used as a coolant in refrigerators and air conditioners the cfc emission reaches the stratosphere and destroys the ozone molecules there. The first problem is the pollution of the lower atmosphere, called the troposphere, with ozone which largely results from photochemical reactions involving man-made emissions from industry and automobiles (smog or photo-smog. The problem of ozone depletion thus threatens to get even more out of hand than it is already, and the risks it poses can't all be dealt with by a bottle of sun block and a wide-brimmed hat not only does ozone depletion threaten human life through increased incidence of skin cancer.
Natural causes of depletion of ozone layer: ozone layer has been found to be affected by certain natural phenomena such as sun-spots and stratospheric winds but this has been found to cause not more than 1-2% depletion of the ozone layer and the effects are also thought to be only temporary. What is the ozone layer almost always the ozone has only been correlated with the hole in the ozone layer and the damages it has caused to the environment the richness of the ozone layer that makes the hole so significant and the science behind the hole is far less popular. Ozone layer depletion first captured the attention of the whole world in the latter half of 1970, and since then, a lot of research has been done to find its possible effects and causes various studies have been undertaken to find out possible solutions.
