What are major causes of thinning of the ozone layer?

Answer 1

Ozone layer protects our planet Earth from the harmful radiations that comes from the sun. The ozone layer was discovered in 1913 by the French physicists Charles Fabry and Henri Buisson. Ozone layer is a deep layer in earth's atmosphere that contain ozone which is a naturally occurring molecule .

During few decades human activities have resulted in the reduction of ozone layer,the main cause for thinning of ozone layer is excessive release of chlorine and bromine from man-made compounds such as chlorofluorocarbons,halons,and methyl bromide found to have direct impact on thinning of the ozone layer.

Answer 2

It used to be chlorofluorocarbons(CFC)s which when enter the atmosphere change the O3( ozone ) to O2 ( oxygen ) while acting like a catalyst.
The substances that are causing ozone layer depletion are freons, CFC's etc..

These are called as ozone-depleting substances (ODS).

Answer 3

Major causes of thinning of the ozone layer include human-made chemicals called chlorofluorocarbons (CFCs), halons, and other ozone-depleting substances used in products like refrigerants and aerosol sprays. These substances release chlorine and bromine atoms when they reach the stratosphere, which then break down ozone molecules. Additionally, natural processes like volcanic eruptions can also contribute to ozone depletion.

Answer 4

Hairspray,car exhaust,smog,anything harmful to humans baiscally.

Answer 5

The ozone hole is caused by CFC's. They react with ozone to deplete it.

Answer 6

The major cause as said by many scientists is CFC's. These are the major cause.

Answer 7

The thinning of ozone layer can be man made or by natural casues. Natural includes the UV radiations while the man made chemicals like CFC's are responsible for the ozone depletion.

Answer 8

The chemical cause is decomposition. Ozone decomposes and then the layer gets thinner.

Answer 9

CFC's cause this. They deplete the ozone.
