Rock stratification
WebStratigraphy is the study of layered materials (strata) that were deposited over time. The basic law of stratigraphy, the law of superposition, states that lower layers are older than … WebSedimentary rocks typically occur in horizontal layers called strata. In undisturbed strata, younger layers sit on top of older ones. This is known as the law of superposition. Strata can be cut by other geologic features, such as faults …

WebIn geology, cross-bedding, also known as cross-stratification, is layering within a stratum and at an angle to the main bedding plane. The sedimentary structures which result are roughly horizontal units composed of inclined layers. The original depositional layering is tilted, such tilting not being the result of post-depositional deformation.
WebIn geology and related fields, a stratum (PL: strata) is a layer of rock or sediment characterized by certain lithologic properties or attributes that distinguish it from adjacent layers from which it is separated by visible … WebWhen overlying rock is removed, underlying strata expand and stretch, creating unloading joints parallel to the surface. Jointing increases erosion rates by creating fissures which …
Stratigraphy is a branch of geology concerned with the study of rock layers (strata) and layering (stratification). It is primarily used in the study of sedimentary and layered volcanic rocks. Stratigraphy has three related subfields: lithostratigraphy (lithologic stratigraphy), biostratigraphy (biologic stratigraphy), and chronostratigraphy (stratigraphy by age).
