how did the evolution of photosynthetic life alter earth's the atmosphere?
carbon dioxide began to dissolve into the ocean at a faster rate
hydrogen moved to the top of the atmosphere and most of it escaped
into space
oxygen began to accumulate in the atmosphere as it was released by
organisms
ammonia molecules were broken down into nitrogen and hydrogen due
to lightning strikes

These molecules of gas moved so fast they escaped Earth's gravity and eventually all drifted off into space. Earth's original atmosphere was probably just hydrogen and helium, because these were the main gases in ... Drawing of part of Earth's surface, with water, carbon dioxide, and ammonia molecules.

I hoped this helped:)
