• Depletion of ozone and formation of ozone hole • Ozone‚ in fact is a gas having fishy smell and O3 molecules which works as the protective shield for the life in the earth. It absorbs solar ultraviolet radiations and thereby protects life on the earth from several damage such as DNA mutation‚ skin cancer‚ blood cancer‚ etc. In the year 1985‚ NASA detected the thinning out of the ozone layer leading to the formation of ‘ozone hole’ in Antarctica. Since then the scientists have been regularly

Effect of CCl3F on Canada’s Ozone Layer Data Analysis and Interpretation 1. It took 25 yrs for CCl3F to enter the stratosphere (1930 to 1955). 2. The ozone layer above Canada began to decline in 1975. 3. Once the production of CCl3F was drastically reduced‚ it took 20 years for the CCl3F levels to decrease in the stratosphere. Conclude and Communicate 4. CFCs (Chlorofluorocarbons) are inorganic man-made chemicals that have been in production for more than 50 years in Canada. They were

stratosphere. Tropospheric ozone is undesirable since it is a pollutant these‚ causing photochemical smog and greenhouse effect. In the stratosphere‚ it acts as a protectant since‚ (i) It absorbs the dangerous UV-radiations (ii) It helps to trap the weather pattern within the troposphere‚ by generating a temperative inversion in the stratosphere. Tropospheric ozone is increasing due to human activities‚ while stratospheric Or‚ is decreasing. This decrease is called Ozone Depletion Ozone depletion deals

Article Reflection: Ozone Layer Ozone: The Pollution Paradox This article was based on information about ozone pollution. In my opinion this article gave a lot of valuable information and I learned a lot of things I never had knowledge of. For example‚ the atmosphere forms and destroys the ozone‚ the ozone can have an effect on the human body and the article also provided information on what we could do about the ozone layer to help the atmosphere. I had a little bit of information in my
Premium Ozone Ozone layer Atmosphere
The upper layer of the atmosphere surrounded by ozone (15 to 30 Kms) is known as ozonosphere. Ozone layer is a protective stratospheric layer‚ also known as ozone umbrella. Ozone concentration differs by about 10 ppm in stratosphere compared to 0.05 ppm in troposphere. It acts as a protective shield for the man‚ animals and plants by filtering out the lethal ultraviolet rays from reaching the earth’s surface. If the ozone layer is not there‚ the harmful ultraviolet rays will reach to the

year‚ the International Day for the Preservation of the Ozone Layer is celebrated. This date has been designated by the United Nations General Assembly in its resolution 49/114‚ to commemorate the signing of the Montreal Protocol on Substances that Deplete the Ozone Layer. | This commemoration around the world offers an opportunity to focus attention and action at the global‚ regional and national levels on the protection of the ozone layer. All Member States are invited to devote this special

Ozone Our Global Sunscreen By Mike Carlowicz t’s not often that scientists get to conduct experiments that seem like they come out of a science fiction novel or a video game. Yet‚ that is what some researchers at NASA did a few years ago. Atmospheric physicists Paul Newman and Luke Oman built a simulation of the Earth’s atmosphere and then proceeded to strip away our protective ozone layer. Their computer model reproduced the chemistry and circulation of the air; natural variations in temperatures
Premium Ozone Ozone depletion
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
Premium Ozone layer Ozone depletion Ultraviolet
The ozone layer diminishes more each year. As the area of polar ozone depletion (commonly called the ozone hole) gets larger‚ additional ultraviolet rays are allowed to pass through. These rays cause cancer‚ cataracts‚ and lowered immunity to diseases.1 What causes the depletion of the ozone layer? In 1970‚ Crutzen first showed that nitrogen oxides produced by decaying nitrous oxide from soil-borne microbes react catalytically with ozone hastening its depletion. His findings started
