.Does the concentration of these gases vary? Support your answer with two examples.​

Answer 1

Each line represents a different data source. This figure shows concentrations of several halogenated gases (which contain fluorine, chlorine, or bromine) in the atmosphere, measured in parts per trillion (ppt). ... This is because the concentrations of different halogenated gases can vary by a few orders of magnitude.
