• 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

Every time 1% of the ozone layer is depleted‚ 2% more UV-B is able to reach the surface of the planet. So in short‚ without the ozone layer everything on earth will burn. The ozone layer is just as important to us as oxygen‚ without it the harmful UV radiation would give us server burns and destroy our delicate ecosystems. Even though there is hard evidence that proves that ozone depletion is harmful for organisms on earth‚ there are a few groups who think that the ozone layer is a “myth” aka doesn’t

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

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

ROLE OF YOUTH IN OZONE LAYER PROTECTION Ozone layer plays a vital role in protecting animals‚ human beings and plants from ultraviolet radiation. Ozone layer is destroyed by a group of manufactured or human made chemicals such as chlorine bromine. These chemicals are called "ozone-depleting substances". Ozone layer is destroyed by some natural’s ways and some humane made activities. A single molecule of chlorine can break apart thousands of molecules of ozone. Chlorofluorocarbons the most widely

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

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

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
