use of cfc (Choloro floro Carbon) degrades and destroys the Ozone layer. It is responsible for filtering out damaging form of Ultra Violet rays of the sun.
Ozone layer is a layer of ozone molecules. It is destroyed by man made CFC's.
Ozone layer was not made by humans but naturally. It was made for the purpose of protecting life on earth.
Humans have eroded the ozone. It is because of man made CFC's.
Humans have eroded the ozone. It is because of man made CFC's.
The ozone layer is damaged over the poles. It is due to the low temperature.
Ozone layer is made up of ozone. It is an allotrope of oxygen.
See "What is the ozone layer?"
The man made objects in ozone layer are CFC's. They are harmful to ozone.
Ozone is continually made by the Sun. Ozone made at Earth's surface does not survive to reach the ozone layer.
Human activities cause release of CFC gases which are pollutants are responsible for the depletion of ozone layer. CFC convert ozone to oxygen and make it useless for the absorption of UV radiation.
Ozone layer is made of O2 only. It is because ozone is an allotrope of oxygen.
ozone layer disappears due to man made chemicals. These are CFC's that damage the ozone layer.
