Question

how ozone layer is formed and the importance of ozone gas

Answer 1

Hyy dear
Formation: The UV light that the ozone layerprotects us from is a necessary component in the creation ofozone molecules. When UV rays strike an oxygen molecule, it breaks the oxygen down into two atoms of oxygen. Then, when those oxygen atoms come into contact with oxygen gas, they join to become ozone.
Importance: Ozone is a gas in the atmosphere that protects everything living on the Earth from harmful ultraviolet (UV) rays from the Sun. Without the layer of ozone in the atmosphere, it would be very difficult for anything to survive on the surface.
Hope it will help you..

Answer 2

                                     FORMATION                                                                            

     WHEN UV(ULTRAVIOLET RAYS) COMES IN CONTACT WITH ATMOSPHERIC O₂ .MOLECULAR OXYGEN SPLITS INTO TWO OXYGEN ATOMS.WHEN THESE OXYGEN COMES IN CONTACT WITH ANOTHER OXYGEN ATOM                      

                 IT FORMS OZONE!!!!!!!!!!!!

                                                                         

                                    IMPORTANCE                                                                        

• IT PROTECTS US FROM THE HARMFUL  UV RAYS.

• IF IT IS NOT THERE ,THEN WE WOULD BE SUFFERING FROM                         SKIN BURNS & SKIN CANCER.  
• NO OZONE ,NO CROP.
