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

Ozone Depletion (Author’s name) (Institutional Affiliation) Abstract Environmental issues have been a major consideration in the World today. Many laws and regulations have been made to protect the environment. Conferences and meetings have been held in several countries to discuss the issues (Solomon‚ et.al‚ 1987). Introduction Ozone depletion refers to the destruction of the stratospheric ozone which is caused by various factors. It happens

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

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

The ozone layer is a deep layer in the stratosphere‚ encircling the Earth‚ that has large amounts of ozone in it. The layer shields the entire Earth from much of the harmful ultraviolet radiation that comes from the sun. Interestingly‚ it is also this ultraviolet radiation that forms the ozone in the first place. Ozone is a special form of oxygen‚ made up of three oxygen atoms rather than the usual two oxygen atoms. It usually forms when some type of radiation or electrical discharge separates

Before I talk about the ozone hole‚ I would like to talk about what ozone is. Ozone is a gas that is made of three oxygen atoms and it’s found up in the atmosphere (stratosphere layer). These three oxygen atoms are so important to us because they protect us from UV radiation. When UV rays try to come to earth they come across these three oxygen atoms and hits them‚ converting them into oxygen gas (O2) and one more oxygen (O). That prevents the UV rays from coming to earth. Ozone hole means that it’s

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.

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. Some ultraviolet radiation still gets through

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
