Definition
Stratification describes the arrangement of something into layers or categories. Think of it like a layered cake 🎂, where each layer is distinct. It's used in geology to describe rock layers and in sociology to describe social classes. Unlike a random pile, stratification implies a structured hierarchy. Stratification also appears in ecosystems. It helps understand complex systems by breaking them down into manageable parts. It reveals underlying patterns, like income inequality or the formation of sedimentary rock.
