Why Do Trees Whisper in the Wind?

Imagine you're holding a wooden ruler and gently push it from one side. It makes a soft creak. Trees are like giant rulers, and when the wind pushes against them, they make sounds too. Some trees have leaves that rustle in the air, while others creak like old doors because their trunks are bending and stretching from top to bottom. When you hear a tree whisper in the wind, it's just doing its own version of a creak or rustle.
