Air is everywhere around us. We cannot usually see air, but we can feel it when it moves.

Meaning of Wind

Wind is moving air.

When air moves from one place to another, we feel it as wind. Examples:

We can know that air is moving when:

1. Leaves shake.
2. Curtains move.
3. A flag waves.
4. Paper is blown away.
5. We feel cool air on our skin.

Simple Demonstration

Place a small piece of paper on a table. Blow on it. The paper moves because moving air pushes it. 💨 ➡️ 📄
