Nature's Gifts

Air is all around us. It is a mixture of gases that every living thing needs to live. Air helps us breathe, moves clouds in the sky, and plays a vital role in changing the weather. Air movement initiates water evaporation, cloud formation, and rainfall. Air carries pollen and seeds, helping plants pollinate and spread. Air is made up of 78% nitrogen and 21% oxygen. 0.03% of the air is carbon dioxide, which is essential because plants use it to make food and release oxygen during photosynthesis. Other gases, such as neon, helium, methane, ozone, and water vapor, are also present in small amounts in air. Air takes up space, has weight, and pressure. When air gets warm, it expands and takes up more space, pushing air around the world, creating and changing weather, and balancing the temperature. Watch the Earth’s Energy Balance as Air helps control the Earth’s temperature by trapping heat and distributing it evenly across the planet, thereby balancing the weather, temperature, and environment.

Breathe in. Breathe out. Be thankful for air!
