Answer:

Three-fourths of all air resides in the troposphere, the lowest layer of the Earth’s atmosphere. Air is a mixture of gases, most of which are naturally occurring. Air also contains a significant amount of human-made air pollutants, including some that are not safe to breathe and some that warm our planet’s climate. The troposphere also contains water in all three phases (liquid, solid, and gas) as well as solid particles, called aerosols.
