Air
| Air is the mixture of gases (predominantly nitrogen and oxygen with small amounts of argon, carbon dioxide, and water vapor) that make up the Earth's atmosphere, which enables living creatures to exist. The atmosphere is the gaseous layer that surrounds the planet, mixes with the planet's water, and penetrates into the soil. |
