The Earth’s ozone layer is supposed to protect people from the Sun’s harmful ultraviolet rays‚ but in the 1970s‚ scientists found out that some chemicals let out into the atmosphere makes the ozone turn into oxygen‚ which means that more ultraviolet rays reach the Earth. During the 1980s‚ scientists found that the ozone layer above the South

    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

    Why is our Ozone Layer is Being Destroyed? Ozone breaks down in the ozone layer in the following major ways: * N2O* encounters water vapor‚ and can no longer help form ozone. * Ozone absorbs UV-C or UV-B and most of it will break back down to oxygen. * Ozone has a natural half-life‚ and decays spontaneously with time and temperature back to oxygen. * Ozone encounters water vapor‚ and forms hydrogen peroxide. * Ozone encounters a photocatalyst (like CFC‚ HCFC‚ Halon)‚ and is

    relationship between the hole in the ozone layer and global warming we must first understand what they are. The hole in the ozone layer is mainly over Antarctica but can sometimes be seen over the North Pole. The ozone depletion is caused by CFCs that were released by aerosol cans and refrigerates before they were banned in 1996. Yet these chemicals don’t disappear right away they can stay in our atmosphere for over fifty years causing the molecules of the ozone layer to breakdown creating a hole. Global

    Science Folio Chapter 5 B6D5E1 Title: Importance of maintaining the cleanliness of air Introduction The atmosphere of Earth is a layer of gases surrounding the planet Earth that is retained by Earth’s gravity. The atmosphere protects life on earth by absorbing ultraviolet solar radiation‚ warming the surface through heat retention (greenhouse effect)‚ and reducing temperature extremes between day and night. One of the most important factors drawing international attention which is

    humans. Smog and ozone layer depletion are two major causes. They are both toxics in the air that humans create and toxics that effect humans as well. Smog is caused by so many different chemicals that ranges from things like automobile exhaust to hairspray. It affects humans mainly in the circulatory and respiratory systems which are both very important and crucial to survive. Ozone layer depletion is a very serious decline of gas in the ozone layer which is bad because the less ozone we have surrounding
