What are the kinds of air?

Answer 1

Air is a mixture of many elements, for example nitrogen, hydrogen, oxygen etc.

The Earth's atmosphere is a layer of gases surrounding the planet Earth that is retained by the Earth's gravity. It has a mass of about five quadrillion metric tons. Dry air contains roughly (by volume) 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.038% carbon dioxide, and trace amounts of other gases. Air also contains a variable amount of water vapor, on average around 1%. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night. There is no definite boundary between the atmosphere and outer space. It slowly becomes thinner and fades into space. An altitude of 120 km (75 miles) marks the boundary where atmospheric effects become noticeable during atmospheric reentry. The Kármán line, at 100 km (62 mi), is also frequently regarded as the boundary between atmosphere and outer space. Three quarters of the atmosphere's mass is within 11 km (6.8 mi; 36,000 ft) of the surface. The above is from Wikipedia. You will get more detailed from Wikipedia. ----

Well if your trying to be funny there's fresh air, foul air, and straight up funky air. But if your being serious there really is only one type of air, it's just composed of many different elements and substances and has different densities of those substances at different times(i.e. different seasons) and at different places(the Sahara vs. the Antarctic).

Answer 2

The main types of air are polluted air, clean air, and indoor air. Polluted air contains harmful particles and gases, while clean air is free from contaminants and is safe to breathe. Indoor air refers to the air inside buildings and can be affected by factors such as ventilation and indoor pollutants.
