Wind is when the air moves from one place to another, like a big invisible push. When the sun heats up the Earth, it warms different parts of the air at different speeds, this makes the air move. Scientists use tools called anemometers to measure how fast the wind is blowing. These look like little spinning cups or fans that spin faster when the wind gets stronger.
Examples
- Anemometers work by spinning when the wind blows. The faster they spin, the stronger the wind feels.
- Wind can be as gentle as a whisper or as strong as a storm, it all depends on how much the air is moving.
