Density, Pressure and Mass.

Explanation:

Air is a fundamental element, being formed by a combination of gases, water vapor and suspended particles, it can be described using the terms density, pressure and mass. It is therefore a vital substance for the maintenance of life on earth, alongside water and soil.

In addition, air is essential for climate, rain distribution and seed dispersion which favor agricultural production. On the other hand, it favors the development of various diseases by viruses, bacteria and microorganisms, which are carried by drafts.

The main elements that make up air are essentially nitrogen (78%) and oxygen (21%) and in small amounts argon (0.94%), carbon dioxide (0.03%), neon (0.0015%). Although it has weight and takes up space in the atmosphere, note that air is a collection of substances that has no color, smell, taste and that we cannot see or touch.

Density, Pressure and Mass are used to describe air.
