The Causes: Effects of Ozone Depletion Cody Tate Buena Vista University Author Note “Prepared for Laura Brauhn’s Globalism Seminar” Abstract This paper will explore what exactly ozone depletion is. It will talk about the definition of ozone depletion and what some of the things are that causes it. This paper will connect global warming with ozone depletion. This paper will give you examples of both biological and environmental. The main thing this paper will talk about is verification

Ozone Depletion Good morning to our lecturer and my fellow friends. Today I want to deliver a speech on title “Ozone Depletion”. Did you know that about 20 kilometres from the earth’s surface there is a thin layer of gas forming just a small fraction of the earth’s atmosphere‚ without which harmful radiation from the sun would destroy all life on this planet? This is the ozone layer‚ which filters out harmful ultraviolet-B rays. Today‚ because of our negligence‚ the ozone layer is depleting.

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

ISSN: 2010-0264 Ozone Layer Depletion and Its Effects: A Review Sivasakthivel.T and K.K.Siva Kumar Reddy Abstract - There are many situations where human activities have significant effects on the environment. Ozone layer damage is one of them. The objective of this paper is to review the origin‚ causes‚ mechanisms and bio effects of ozone layer depletion as well as the protective measures of this vanishing layer. The chlorofluorocarbon and the halons are potent ozone depletors. One of

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

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

Scientific Article: The Ozone Layer The Ozone layer is located in the Earth’s upper atmosphere. It acts as a barrier and absorbs majority of UV radiation before it hits Earth’s surface. Ozone is made up of three oxygen atoms that are naturally occurring molecules. The depletion of the ozone has become a worldwide issue and is caused by the release of CFCs into the atmosphere. CFCs release chlorine atoms which break down ozone molecules. The depletion of the ozone layer threatens to leave life on

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

• 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
