Here are three playful ways to say it:
- Mountains are like crayons: new ones are sharp and tall, and old ones are short and rounded.
- Some mountains wear party hats — young ones are spiky and high; older mountains look like squishy pillows, all soft and round.
- Think of mountains as play‑dough: fresh ones can be made into tall points, but after a long time they get smooshed into gentle bumps.
