The ozone depletion The ozone depletion‚ or ozone hole is a big problem which affects the environment and also all the people on earth. But what is it? Does this problem have a solution? And what are governments doing to reach this solution? The ozone layer is a belt of naturally occurring ozone gas that sits 15 to 30 kilometers above Earth and serves as a shield from the ultraviolet B radiation emitted by the sun which are very dangerous. Now‚ the problem is that the release of pollution

IMPACTS OF OZONE Introduction Ozone is a gas that occurs naturally in our atmosphere. Most of it is concentrated in the ozone layer[->0]‚ a region located in the stratosphere several miles above the surface of the Earth. Although ozone represents only a small fraction of the gas present in the atmosphere‚ it plays a vital role by shielding humans and other life from harmful ultraviolet light from the Sun. Human activities in the last several decades have produced chemicals‚ such as chlorofluorocarbons

Ozone Depletion and Indoor Air Pollution Nainsi McKinney 5/14/13 Ozone depletion is a very serious issue that is almost fully the fault of humans and the ozone is going to continue to thin if changes are not made. Chemicals that are used in everyday life are primarily responsible for the ozone loss; compounds called chlorofluorocarbons such as Freon and Styrofoam when used as a foam blowing agent for insulation (WileyPlus‚Chap.9.

The Ozone Layer: What does it do and what happens when it is depleted? The ozone layer is one of the most debated scientific subjects of the last decade. The growing problem of its depletion is being researched heavily all over the world‚ and methods are being researched to try and solve the problem. There have also been many debates concerning the relationship between the ozone layer and the onset of global warming. Before solutions can be developed‚ however‚ what the ozone layer actually does

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

Ozone depletion Ozone depletion describes two distinct but related phenomena observed since the late 1970s: a steady decline of about 4% per decade in the total volume of ozone in Earth’sstratosphere (the ozone layer)‚ and a much larger springtime decrease in stratospheric ozone over Earth’s polar regions. The latter phenomenon is referred to as the ozone hole. In addition to these well-known stratospheric phenomena‚ there are also springtime polar tropospheric ozone depletion events. The details

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

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

Ozone As A Disinfectant Joey Finnegan Section 01 October 3‚ 2010 Ozone is a highly reactive gas composed of three oxygen atoms. Ozone is an unstable gas that can destroy bacteria and viruses. Ozone can have many different effects on humans depending on where it is in the atmosphere‚. Some of these effects can be harmful although some can be good. An excess‚ or high concentration of ozone in an inclosed area can be quite harmful to humans although in moderation and if used properly ozone
