Assignment – Ozone Debate The debate over whether or not the ozone is actually depleting or not has been a hot topic for some time. However‚ it becomes a hotter topic when scientists find out it is a lower level then usual. We don’t here much from the debate when it has replenished itself to some amount‚ which it does do during certain seasons. Between the two sides we are to take‚ I am basically right in the middle. I do believe what the NASA website stated about it when it said “the ozone is extremely
Premium Ozone depletion
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

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 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

Essay ozone depletion is a serious problem presently facing the world. The ozone layer protects humans‚ animals‚ and plants from harmful ultraviolet rays. Money and time are being spent on ozone repair‚ but the problem still exists. The ozone layer is a region of the stratosphere containing ozone‚ or O3 gas. The ozone layer is necessary to both plant and animal life on earth because it protects the surface from dangerous ultraviolet light. However‚ manufacturing and household chemicals

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

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")

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

protects us from the full blast of the sun’s radiation. Way up in the part of the atmosphere‚ called the stratosphere‚ a layer of gas filters out most of the sun’s damaging ultraviolet rays. This layer of gas is called ozone and is located about five miles to 25 miles above the surface of the Earth. (Bright‚ 1991). Only about one-millionth of our atmosphere is made up of ozone. But it has a tremendously important job. Ozonecan absorb‚ or soak up‚ the part of sunlight called ultraviolet radiation

continent-size hole in Earth ’s ozone layer keeps getting bigger and bigger. Each year since the late 1970s‚ much of the protective layer of stratospheric ozone above Antarctica has disappeared during September‚ creating what is popularly known as the ozone hole. The Antarctic hole now measures about 9 million square miles‚ nearly the size of North America. Less dramatic‚ still significant‚ depletion of ozone levels has been recorded around the globe. With less ozone in the atmosphere‚ more ultraviolet
