Fall is when leaves change color and fall from trees to the ground.
Leaves are like little hats on the branches of a tree. In summer, they are green because of a special green paint called chlorophyll. But when days get shorter and nights get colder, the tree says, “It’s time for a rest!” So it stops making chlorophyll, and other colors, like yellow, orange, and red, show up underneath.
What Happens to the Leaves?
When the leaves lose their green paint, they become lighter. That makes them easier to shake off the branches when the wind blows or the tree moves a little.
Fall is also a time of change, just like when you switch from your summer clothes to your cozy winter ones.
Why Do Leaves Fall?
Think of it like a big leafy dance party, but then the music stops, and everyone slowly leaves the floor. The leaves go down to the ground, where they might become mulch or stay there for a while, ready to help the tree grow again next year.
