Hill chain

Okay kiddo, imagine you're climbing up a really big hill. It's so big that you can't make it up all by yourself, so you decide to work with your friends to make it to the top. You start by climbing up a little bit, then one of your friends takes over and helps you climb a little higher. Then another friend takes over and helps you climb even higher.

This is kind of like a hill chain! It's when a group of people work together to climb up a hill. Each person takes a turn helping the others climb higher until they all reach the top together.

Just like climbing a hill in real life, it takes teamwork and support to make it to the top. But with a hill chain, it's a little easier because everyone is helping each other out.
