Fining-upward sequence

A "fining-upward sequence" refers to a progression where the size or quality of something increases step by step. In general knowledge contexts, this can be seen in various fields, such as geology or archaeology, where smaller or finer materials are found layered beneath larger or coarser ones. It illustrates a natural or systematic transition where elements become more refined or developed over time. Essentially, this concept helps us understand how processes and artifacts evolve, highlighting the importance of gradual improvement or change in different domains of knowledge.
