Serc: The Sedimentary Processes of Transgression and Regression

This article gives a detailed explanation of how transgression and regression of sea levels work to create deposits of sedimentary rocks. Illustrations show the layering that takes place over time. The article discusses how geologists interpret the rock strata using temporal and spatial thinking, and how the interacting forces often give the strata a complex geometry. It discusses how this process of interpretation can be difficult to convey to students of geology.
