Sedimentary structures are visible textures or arrangements of sediments within a rock. Geologists use these structures to interpret the processes that made the rock and the environment in which it formed. They use uniformitarianism to usually compare sedimentary structures formed in modern environments to lithified counterparts in ancient rocks.

Grand Canyon is a famous place to see just that--each layer's cross section. The principle of original horizontality - sedimentary strata are initially deposited as horizontal or nearly horizontal layers. Note: If sedimentary strata dip at an angle other than horizontal, or are folded into various angles of tilt, then the layers of rock have been tilted or folded after the layers originally formed. Introduction Evolutionists and creationists have different views on the origin of sedimentary rock strata.
