Lightning contributes to the nitrogen cycle by

  • A.converting nitrogen oxides back into nitrogen gas
  • B.having no effect on nitrogen chemistry at all
  • C.fixing atmospheric nitrogen into nitrogen oxides
  • D.removing nitrogen from the atmosphere permanently

Answer: C

The extreme channel temperature allows nitrogen and oxygen to combine. The resulting oxides are a significant natural source in the upper troposphere, where few other sources operate. It matters directly to ozone chemistry at those levels.
