Why Do Trees Grow Rings as They Age?

Trees grow rings because they get bigger every year. Imagine a tree like a cake, each year, it adds a new layer around the outside. In the spring, it grows soft green layers, and in the fall, it turns hard brown ones. That’s why you can see circles inside a tree when you cut it open!
