I wonder how the ozone layer protect life on earth.

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.

Here are some links i found helpful.

Hey Angela, 

It's neat to see what the ozone is made of as I don't know too much about it. A possibility for you upcoming rounds of research is to look into how the ozone layer is in danger, which is super concerning! In an article, there was an ice base that found a hole in the ozone layer in danger of falling into chasm (first link)



Best of luck!


Nice research Angela! 

The ozone layer is very beneficial to us as humans but is unfortunately being destroyed by fossil fuels and greenhouse gasses. Here is a site that discusses how the ozone layer is depleting and why this is such a big problem, not only for us as humans, but for all wildlife around the world. It is a national geographic site.


I hope this helps your research,

Hey Angela am glad to here you researching on how the ozone layer helps to support life on earth.Iam much intrested on your work and I would like to here more from you.I've visited the internet to learn more and I have found that the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (UVR) from the sun, protecting life on Earth from its potentially harmful effects. When the sky is clear, there is an inverse relationship between stratospheric ozone and solar UVR measured at the Earth’s surface. That is,the lower the ozone levels, the higher the solar UVR.

Hi Angela,

This was very interesting research and it is obvious you are very interested in it. I like how you organized it into neat paragraphs so it would be easier for the readers to understand. One thing, what do you think would happen if there were no more ozone layer? What causes the ozone layer to degrade? What would the impact be?
