Ozone layer

  1. Jan 27, 2005 #1
    I have a question about the ozone layer in our upper atmosphere.

    It is my understanding the the ozone is formed by hard radiation for the sun and space striking an O2 molecule and spitting it in two. The free oxygen atom then eventually finds another O2 molecule and attachs itself to forming ozone.

    The ozone then floats around until it is struck again by radiation which splits it back to O2 absorbing the radiation.

    My question is first does the original splitting of O2 also absorb the radiation?

    My next question is that if the ozone layer is depleted by CFC's or whatever wouldn't the radiation simply penetrate our atmosphere a little bit deeper where the atmosphere is denser and strike the more abundant O2 molecules eventually making more ozone to absorb even more radiation, albeit at a deeper level in our atmosphere, rather than the radiation reaching the surface where it can harm us and the rest of life on earth?

    If my thinking is wrong please tell me where and why it is wrong.
