This is what Mr. Wiki has to say: http://en.wikipedia.org/wiki/Cycle_of_erosion.frezzel said:Can someone please explain in simple step by step terms what the cycle of erosion is? I have tryed googling it, but there does not seem to be any simple explanation.
Cheers, freya
However, this doesn't seem to be in the syllabus. The closest thing I can think of is eutrophication.

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)
