What are stratification patterns?

Stratification patterns are how things layer up over time, like when you stack your toys at the end of the day.

Imagine you have a big jar filled with different kinds of candies, gummy bears, chocolate chips, and peppermints. Every night, before bed, you add one more layer to the jar: first all gummy bears, then chocolate chips, and finally peppermints. Over time, you’ll see layers forming in the jar, a pattern that shows when each kind of candy was added.

This is like how stratification patterns work in real life, such as in rocks or even soil. If you look at a rock, it might have different colors or textures stacked on top of each other. Each layer tells a story about what happened back then, maybe there was water, wind, or even a volcano.

Think of the Earth like that candy jar. Over millions of years, layers of dirt, sand, and rock pile up one after another. Scientists look at these layers to understand how the Earth changed long ago, just like you might look at your candy jar to remember which night you added what kind of candy.

So next time you stack your toys or eat a big bowl of candy, remember: you're making your own stratification pattern!
