Rocks are always changing. Most change slowly over many years. The Earth moves and pushes them. The wind blows and wears them down. Water and ice crack them.
Write a letter to a friend about rocks that you saw while taking a walk. Here are some questions to help you:
What kinds of things happen to rocks?
How can you tell why a rock looks the way it does?
How would you describe a rock that you saw?
