Some archaeological strata (often termed as contexts or layers) are created by undercutting previous strata.An example would be that the silt back-fill of an underground drain would form some time after the ground immediately above it.Local relationships on a single outcrop or archaeological site can often be interpreted to deduce the sequence in which the materials were assembled.This then can be used to deduce the sequence of events and processes that took place or the history of that brief period of time as recorded in the .The radiocarbon dating method is based on the fact that radiocarbon is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen.
The resulting data, in the form of a calibration curve, is now used to convert a given measurement of radiocarbon in a sample into an estimate of the sample's calendar age.
Example: analyzing changes in tree growth patterns via tree rings to date a series of landslide events.
The science that uses tree rings to date and study past and present changes in glaciers.
This is important to stratigraphic dating, which assumes that the law of superposition holds true and that an object cannot be older than the materials of which it is composed.
The law was first proposed in the 17th century by the Danish scientist Nicolas Steno.
