carbon tetrafluoride (cf) in our atmosphere is more than 50,000 years. in contrast, carbon dioxide (co2) has a residence time that is much
shorter. which statement best explains how the residence time of a substance affects the atmosphere?
oa. substances that have a longer residence time are more beneficial to the atmosphere.
ob. substances that have a shorter residence time make up a smaller portion of the atmosphere.
oc. substances that have a longer residence time will cycle faster through the atmosphere.
