Bark (botany)

You know how trees have a big, rough outside layer? That's called bark. Bark is like the tree's fancy coat. It protects the tree from bad weather, like strong wind and rain. It also keeps animals from biting the tree or crawling inside it. Think of it like when you put on a jacket to go outside in the cold - it keeps you warm and safe from the cold air. Bark does the same for trees! Sometimes, bark can have different colors or patterns, just like your clothes can have different designs. And just like how people shed their clothes when they get too small or old, trees shed their bark to grow new, fresh bark underneath.
