scientists have discovered that morning fog removes particles in the air that are bad for people with repitory problems. the water particles in the fog are small enough to attach and hold onto small particles in the air. when the fog settles to the ground the air pollutants go with it.
i think thats very interesting because some fogs like "smog" are very harmful to humans but i guess not all fogs are bad. this could help scientists in curing bad fog and figuring out how the water particles work.
