The principal constituents of the atmosphere of Earth are nitrogen (78 percent) and oxygen (21 percent). The atmospheric gases in the remaining 1 percent are argon (0.9 percent), carbon dioxide (0.03 percent), varying amounts of water vapor, and trace amounts of hydrogen, ozone, methane, carbon monoxide, helium, neon, krypton, and xenon.
Snow is roughly 90-95% air, with the rest being frozen water.
The percentage of air in soil varies depending on factors like soil type, compaction, and moisture content. In general, soil samples typically contain around 25-50% of pore space, which includes both air and water.
The percentage of humidity represents the amount of water vapor present in the air compared to the maximum amount it could hold at that temperature. Humidity levels can vary depending on location, weather conditions, and time of day.
The Earth's atmosphere is composed of about 21% oxygen. This level is important for supporting life on our planet.
Around 16% of the air you breathe out is oxygen. This percentage decreases from the 21% of oxygen in the air you inhale due to the exchange of gases that occurs during respiration.
