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.

Incremental dating techniques allow the construction of year-by-year annual chronologies, which can be temporally fixed (i.e., linked to the present day and thus calendar or sidereal time) or floating.

Archaeologists use tree-ring dating (dendrochronology) to determine the age of old pieces of wood.

The direction and magnitude of the magnetic field of the Earth at a particular location varies with time, and can be used to constrain the age of materials.

In conjunction with techniques such as radiometric dating, the technique can be used to construct and calibrate the geomagnetic polarity time scale.

This is one of the dating methodologies used for sites within the last 10,000 years.

The Earth's magnetic field has two main components.

From the standpoint of anthropology and sociology, dating is linked with other institutions such as marriage and the family which have also been changing rapidly and which have been subject to many forces, including advances in technology and medicine.The Law of Superposition, which states that older layers will be deeper in a site than more recent layers, was the summary outcome of 'relative dating' as observed in geology from the 17th century to the early 20th century.The regular order of occurrence of fossils in rock layers was discovered around 1800 by William Smith.Relative dating is the science of determining the relative order of past events (i.e., the age of an object in comparison to another), without necessarily determining their absolute age, (i.e. 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.These people will have dates on a regular basis, and they may or may not be having sexual relations.
