The effects of the generation of free oxygen during the late Precambrian on our planet.
Answer to Problem 17TE
The generation of free oxygen during the late Precambrian led to formation of ozone layer and evolution of new organisms in on our planet
Explanation of Solution
The oxygen released by plants during photosynthesis was accumulated in iron deposits before the late Precambrian period. When the oxygen generation overcame the oxygen accumulation in iron deposits, free oxygen started to fill the atmosphere in the late Precambrian period.
The free oxygen was combined with other oxygen atoms to form ozone gas. The ozone gas started to form a layer above the earth, protecting the earth from harmful ultraviolet
Conclusion:
Therefore, the generation of free oxygen during the late Precambrian led to the formation of the ozone layer and evolution of new organisms in on our planet.
