Ozone DepletionOzone Depletion
Ozone layer consists of a Ozone layer consists of a layer of gas (Olayer of gas (O33))
Function Function block the UV block the UV rays from reaching rays from reaching the Earth surfacethe Earth surface
Depletion cause by due the ozone Depletion cause by due the ozone depleting subtances :depleting subtances : CFC CFC HCFC (more safety than CFC) HCFC (more safety than CFC) Halons (fire extinguishing)Halons (fire extinguishing)
