Process of ozone hole formation
WebbOzone–oxygen cycle in the ozone layer: 1. Oxygen photolyzed to atomic oxygen 2. Oxygen and ozone continuously interconverted. Solar UV breaks down oxygen; molecular and … WebbOzone layer depletion is the deterioration of the upper atmosphere's ozone layer. This occurs when chlorine and bromine atoms in the atmosphere react with ozone, destroying the ozone molecules. One chlorine atom may destroy 100,000 ozone molecules, destroying faster than its formation.

WebbThe chlorine atom breaks an ozone molecule apart into an oxygen molecule (O 2) and a chlorine monoxide molecule (ClO). A free oxygen atom bumps the chlorine atom out, forming an oxygen molecule. This leaves the chlorine atom free to attack and destroy another ozone molecule. UCAR/COMET WebbThis thinning of the ozone layer over Antarctica came to be known as the ozone hole. This series of images shows the size and shape of the ozone hole each year from 1979 …

Short-wavelength UV radiation splits an oxygen (O 2) molecule into two oxygen (O) atoms, which then combine with other oxygen molecules to form ozone. Ozone is removed when an oxygen atom and an ozone molecule "recombine" to form two oxygen molecules, i.e. O + O 3 → 2O 2.
