GENERAL GEOLOGY

Detailed explanation-1: -Rock layers are also called strata (the plural form of the Latin word stratum), and stratigraphy is the science of strata. Stratigraphy deals with all the characteristics of layered rocks; it includes the study of how these rocks relate to time.

Detailed explanation-2: -Stratigraphy (noun, “Strah-TIG-grah-fee”) This is a branch of geology that focuses on geological strata, or rock layers. The ground beneath your feet is not one solid mass. It has layers, like the layers of an onion, on its outer crust. These layers build up over time.

Detailed explanation-3: -Stratigraphy is a branch of Geology and the Earth Sciences that deals with the arrangement and succession of strata, or layers, as well as the origin, composition and distribution of these geological strata. The study of archaeological and natural stratification therefore involves the assessment of TIME and SPACE.

Detailed explanation-4: -Stratigraphy is the branch of geology which studies rock layers (strata) and layering (stratification). Stratigraphy deals primarily with sedimentary rocks but also embraces layered igneous rocks where layers result from successive lava flows.

Detailed explanation-5: -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).
