This happens during lightning. The enormous energy of lightning breaks nitrogen molecules and enables their atoms to combine with oxygen in the air forming nitrogen oxides. These oxides dissolve in rain water to give nitric and nitrous acids that are carried to the earth.
Atmospheric nitrogen fixation probably contributes some 5– 8% of the total nitrogen fixed.
