Definition: Stratigr means "stratified", which comes from the Greek term "sthrax" meaning "to divide" or "to separate". It refers to the division of a rock into layers, typically by a stratigraphic layer. The word is commonly used in geological contexts to describe the process of sedimentation and the formation of new bedrock over time. For example, an example of this term being used could be in the study of ancient sedimentary rocks, where the strata can be divided based on their composition or age.

Stratigr

Definition: The word "stratigraphy" is a scientific term that refers to the systematic classification and study of rock, soil, and other geological materials based on their chemical composition, structural features, and age. Stratigraphy is used in many areas of science and engineering, including geology, archaeology, environmental science, and paleontology. It provides a complete picture of an entire rock or soil sample or group, including the layers they are made up of, the mineralogy of each layer, and any significant geological processes that have affected the materials. In stratigraphy, a stratigraphic unit is a set of rocks or other geologic material in a specific order. The "unit" may include various types of rock such as sedimentary rocks, igneous rocks, metamorphic rocks, or volcanic rocks. Each layer in a stratigraphic sequence has a name and description that reflects its composition and the processes that have influenced it. Stratigraphy is widely used to describe the chronological order of geological events, such as the formation of new rock layers over time. It can be applied to a wide range of topics including the geology of different continents, the movement of tectonic plates, and the distribution of mineral resources in a region.
