The concept of formally defined layers or strata is central to the geologic discipline of stratigraphy, and the formation is the fundamental unit of stratigraphy. Formations may be combined into groups of strata or divided into members. Members differ from formations in that they need not be mappable at the same scale as formations, though they must be lithologically distinctive where present. http://api.3m.com/gaps+in+rock+layers+are+called+____
WebGeologic History. Geologists use stratigraphy, the study of rock layers, to understand how environments change over time.
