However, this doesn't seem to be in the syllabus. The closest thing I can think of is eutrophication.

31 Oct 2007, 2:08 PM | By erosion do you mean the depletion of the ozone layer? If so: Ozone in the stratosphere is constantly being formed and decomposed by natural effects. The ozone formed strongly absorbs ultraviolet radiation and undergoes photochemical decomposition to form O2 and oxygen atoms. O3(g) -->O2(g) + O(g) But that is the natural process, the depletion of the ozone layer occurs when certain molecules find their way up into the ozone layer. An example would be NO(g): NO(g) + O3(g) -->NO2 O2(g)
