Sprays containing fine particles that become suspended in the atmosphere are called?

• A. Vapors
• B. Dust
• C. Emissions
• D. Aerosols

Answer: (D)

Fine particles that remain suspended in the air are called aerosols. They can be tiny solid particles or liquid droplets, such as smoke, soot, dust, sea spray, pollen, or volcanic ash. They stay in the atmosphere because of their small size, allowing them to be carried long distances and to affect climate and health. This differs from vapors, which are gases, and from emissions, which describes the release of pollutants rather than the state of being suspended. While dust is a type of airborne particle, the term aerosols specifically refers to these suspended particles in the atmosphere.
