Hi everyone i will be researching on how beneficial the ozone layer is to us.
The ozone is a deep layer in the stratosphere encircling the earth that has large amount of ozone in it.Its also known as the ozone shield .It was discovered in 1913 by the french physicist Charles Habry and Henri Buisson. It is found in two of the earth's atmosphere.It begins at about 6 miles above and extends to around 30 miles above.
The ozone is made of the major gases like argon, nitrogen and oxygen.It also contains larger amounts of the trace gas ozone than the other layers of the atmosphere.Trace gases include carbon dioxide,neon, helium,methane and the man made chlorofluorocarbons.
Some of the benefits of the ozone layer include Protection against diseases like cancer and catararcts. It also protects the environment and ecosystems. Chlorofluorocarbons [CFCs] are the primary causes for the ozone layer depletion.They include solvents,soaps and spray aerosols.
The CFCs reaching,the stratosphere from the earth's surface have become a cause for global concern because of the role they play in the chemical reaction that removes ozone from the atmosphere.
