A little about the video
Relative dating is the science of determining the relative order of past events i. In geology, rock or superficial deposits , fossils and lithologies can be used to correlate one stratigraphic column with another. Prior to the discovery of radiometric dating in the early 20th century, which provided a means of absolute dating , archaeologists and geologists used relative dating to determine ages of materials. Though relative dating can only determine the sequential order in which a series of events occurred, not when they occurred, it remains a useful technique.

5 Key Principles of Relative Dating in Geology - Owlcation - Education

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 two related subfields: lithostratigraphy lithologic stratigraphy and biostratigraphy biologic stratigraphy. Catholic priest Nicholas Steno established the theoretical basis for stratigraphy when he introduced the law of superposition , the principle of original horizontality and the principle of lateral continuity in a work on the fossilization of organic remains in layers of sediment. The first practical large-scale application of stratigraphy was by William Smith in the s and early 19th century.
