Which term describes minute particles of solid and liquid matter suspended in the atmosphere?

The term that accurately describes minute particles of solid and liquid matter suspended in the atmosphere is "aerosol." Aerosols can include a variety of particles, such as dust, smoke, and other liquids like mist or spray. They are characterized by their ability to remain suspended for extended periods due to their small size, which allows them to be transported over long distances by airflow.

Dust is primarily made up of solid particles and can settle relatively quickly, whereas smoke consists of solid and liquid particles produced from combustion, also settling more quickly than aerosols. Vapor refers to the gaseous state of a substance that is typically liquid at room temperature. Thus, the broadest and most inclusive term that encompasses all forms of minute particles suspended in the air is aerosol, representing both solid and liquid materials effectively.
