Strata form during sediment deposition, that is, the laying down of sediment. Meanwhile, if a change in current speed or sediment grain size occurs or perhaps the sediment supply is cut off, a bedding plane forms. Bedding planes are surfaces that separate one stratum from another. A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics (lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. chattering teeth dog meme
