Click to see full answer. Consequently, what are the principles of relative dating? Geologists establish the relative ages of rocks mostly through their understanding of stratigraphic succession. The Principle of Original Horizontality states that all rock layers were originally horizontal. The Law of Superposition states that younger strata lie on top of older strata.

Difference Between Relative Dating and Absolute Dating
Relative dating - Wikipedia
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. Relative dating by biostratigraphy is the preferred method in paleontology and is, in some respects, more accurate. The regular order of the occurrence of fossils in rock layers was discovered around by William Smith. While digging the Somerset Coal Canal in southwest England, he found that fossils were always in the same order in the rock layers.
Geologic Principles—Cross-cutting Relationships
In the field of Geology, dating is an important term as it is a technique through which evaluation regarding the age and period about the fossil, remains, the archaeologists do valuables and artifacts. At first, there were not many methods of dating were available, but now with advancement in the technology, we mainly have two types of techniques to ascertain ages of ancient belongings. Relative Dating and Absolute Dating are two types of such techniques which are under practice to determine the age of the fossils, objects or civilizations. The relative dating is the technique in the Geology through which the age is determined with relation to the other objects. In other words, we can say that in relative dating the archaeologist determines that which of the two fossil or the artifacts are older.
Geologists often need to know the age of material that they find. They use absolute dating methods, sometimes called numerical dating , to give rocks an actual date , or date range, in number of years. This is different to relative dating , which only puts geological events in time order.
