What does the principle of lateral continuity suggest about sedimentary strata?

The principle of lateral continuity indicates that sedimentary strata extend laterally in continuous sheets across a broad area. This principle suggests that, unless obstructed by a physical barrier such as a mountain range or erosion, sedimentary layers will typically be deposited in a flat and horizontal manner, covering large expanses of land. Therefore, when observing sedimentary rock formations, if one layer is present in one place, it is reasonable to assume it also continues horizontally into adjacent areas, unless disrupted.

The concept does not support the idea that sedimentary layers are formed in vertical stacks or that they consist solely of volcanic materials, which are distinct from sedimentary processes. Additionally, the principle does not imply that strata will be found at uniform depths in all locations; instead, variations can occur due to geological processes over time, such as erosion or tectonics. The understanding of lateral continuity is essential for interpreting geological formations and sediment deposition patterns.
