Air is like a big invisible blanket around us! 🌬️ It's made mostly of two special gases called oxygen and nitrogen. We breathe in oxygen to stay alive, and plants love it too! 🌱
There's also tiny bits of other things in the air, like water and dust. That's why we sometimes see clouds or feel wind!
Air is a mix of gases that surrounds Earth like a protective bubble! 🌍✨ The two main gases are:
There’s also tiny amounts of other gases like carbon dioxide (which plants love) and water vapor (hello, clouds! ☁️). Even dust and pollen float in the air!
Air is a carefully balanced mixture of gases that make life on Earth possible! Here’s the breakdown:
| Gas | Percentage | Role |
|---|---|---|
| Nitrogen (N₂) | 78% | Dilutes oxygen, prevents fires 🔥 |
| Oxygen (O₂) | 21% | Essential for breathing and energy 🏃 |
| Argon (Ar) | 0.9% | Inert gas (used in light bulbs 💡) |
| CO₂ + others | 0.1% | CO₂ fuels plant photosynthesis 🌿 |
Air also contains water vapor (humidity 💧) and microscopic particles like pollen or pollution. The atmosphere’s layers (like the ozone layer) protect us from space radiation! ☢️➡️🛡️
