💬 Think about it
Fallen leaves suddenly rise and swirl, a door slams shut on its own, clothes flap on the line, a tree bends low — all when the wind blows. The wind is pushing on them. But how does moving air push so hard? That push is the start of our whole story.
How does wind make leaves rise and trees bend?
- Wind exerts a force on objects in its path.
- This force creates wind pressure.
- Wind pressure makes leaves rise, doors slam and trees bend.
Example:
A gust rattling the windows or fluttering your clothes is wind pressure at work.
What will this chapter explore?
- The relationship between force and pressure.
- How liquids and air exert pressure.
- How pressure differences shape winds, thunderstorms and cyclones.
