10) A thermal inversion, which can lead to serious pollution events, occurs when

warm air that normally rises does so, taking the pollutants with it.
warm air that normally rises stays close to the surface, holding pollutants close to the surface.
cool air that normally rises does so, taking the pollutants with it.
cool air stays close to the surface but pollutants rise into the atmosphere.
cool air stays close to the surface and is blanketed by a layer of warm air that traps pollutants.
