Ozone forms readily in the stratosphere as incoming ultraviolet radiation breaks molecular oxygen (two atoms) into atomic oxygen (a single atom). In that process, oxygen absorbs much of the ultraviolet radiation and prevents it from reaching the Earthâs surface where we live.
What happen to the water molecules when the plants absorbs light energy during photosynthesis? The water molecules split into hydrogen ions, electrons and oxygen atoms. The oxygen atoms join together to form oxygen molecules = oxygen gas which is released from the plantâ¦ into the air.
