Visible air is a term used to describe the air that we can see, which is made up of various components such as VAPOR, SMOG, and HAZE. VAPOR is a gas that is composed of tiny droplets of water or other liquids suspended in the air. SMOG is a type of air pollution that is created by the burning of fossil fuels and is characterized by a thick, murky HAZE. HAZE is a type of air pollution that is caused by dust, smoke, and other particles suspended in the air. All three of these components are visible in the air and contribute to the overall quality of the air we breathe.
