Document Summary

M1 the bottom because the heavy gas applied. Oh is very important species, take out the minus you get a reactive species. Photon is involved in every atmospheric reaction. There are ozone depletion, smog and acid rain. What we do also affect the atmosphere. N2o + hv -> n+, o+, o2+, n2+ hv: light is consumed in this reaction. Photon get destroyed as much as the n2o. Shorter wavelength don"t reach the surface of earth. N2o + hv -> n+, o+, o2+, n2+ (wavelength < 100 nm) O2 + hv -> o + o (wavelength < 200 nm) O3 + hv -> o2 + o (wavelength < 325 nm) Oxygen absorb wavelength less than 200 nm. Ozone absorb wavelength less than 325 nm. Photon are very dangerous to cause skin cancer and can even destroy your dna. Light is absorb by the first reaction. There are more radiation in the atmosphere. The higher it is the more dangerous.
