What is bark?

Bark is the rough outer layer of a tree, kind of like a tree’s skin.

Imagine you have a favorite sweater that gets worn every day. Over time, it starts to get scratchy and worn out on the outside. That’s what happens to a tree, instead of getting a new sweater, it grows a thick, tough layer called bark. This helps protect the tree from animals, cold weather, and even little cuts or scratches.

How Bark Grows

When a tree is young, its skin is soft and smooth. But as it gets older, it starts to grow more layers on top, like adding extra padding around your favorite toy. These layers make the bark rougher and harder over time.

Why Trees Need Bark

Bark acts like a shield for the tree. It helps keep the inside of the tree safe from harm. Without bark, trees would be like cookies with no chocolate, they’d be too soft and easy to break!

So next time you touch a tree’s rough outside, remember, that’s its special armor, helping it stay strong and healthy! Bark is the rough outer layer of a tree, kind of like a tree’s skin.
