how is Ozone formed in the upper atmosphere state its importance what is responsible for its depletion write one harmful effect of ozone depletion
Answers
Answer:
Explanation:
Ozone depletion. Ozone depletion, gradual thinning of Earth's ozone layer in the upper atmosphere caused by the release of chemical compounds containing gaseous chlorine or bromine from industry and other human activities. The thinning is most pronounced in the polar regions, especially over Antarctica.
The ultraviolet rays of the sun split Oxygen molecule (O2) into nascent oxygen (O).
O2 -> O + O
The nascent Oxygen combines with other Oxygen molecule to form Ozone (O3)
O + O2 -> O3
It is important as it reflects back the UV rays of the sun which are harmful for the organisms on Earth.
Ozone depletion is caused by excessive use of CFC releasing gadgets like ACs, refrigerators, etc. Solar flares and solar storms are also responsible for its depletion.
Ozone depletion will cause the passage of UV rays that are harmful. They can cause skin cancer and cataract.
