Air is primarily a mixture of gases, and its composition can vary slightly depending on location and altitude. The major components of dry air are:
1. **Nitrogen (N₂)** - about 78%
2. **Oxygen (O₂)** - about 21%
3. **Argon (Ar)** - about 0.93%
4. **Carbon Dioxide (CO₂)** - about 0.04% (varies with time due to human activity)
5. **Trace gases** - including neon, helium, methane, krypton, and hydrogen, among others, which make up the remaining fraction.
In addition to these gases, air can also contain water vapor, which varies significantly in concentration (from nearly 0% to about 4% by volume) depending on humidity and environmental conditions.
