I am hoping someone could provide a couple of examples of Chronometric Vs relative dating technologies so I can grasp this further..

You get an exact age, so that is chronometric dating.However, the stratigraphic position alone cannot tell us the exact date.ARCA’s staff and network of specialist associates offer a wide range of laboratory analyses which allow the reconstruction of past environmental conditions, the identification of human activity/modification of sediments, and the potential for preservation of archaeological remains to be assessed.Click on the "Show Movie" button below to view this animation.C-14 Decay Profile Clicking on the "Show Movie" button below will bring up an animation that illustrates how a C-14 sample is processed and the calculations involved in arriving at a date.As the Earth's upper atmosphere is bombarded by cosmic radiation, atmospheric nitrogen is broken down into an unstable isotope of carbon - carbon 14 (C-14).

The unstable isotope is brought to Earth by atmospheric activity, such as storms, and becomes fixed in the biosphere.

This is actually a mini-simulator, in that it processes a different sample each time and generates different dates.

Without the ability to date archaeological sites and specific contexts within them, archaeologists would be unable to study cultural change and continuity over time.

Chronometric dating techniques produce a specific chronological date or date range for some event in the past. Relative dating techniques, on the other hand, provide only the relative order in which events took place.

For example, the results of dendrochronology (tree-ring) analysis may tell us that a particular roof beam was from a tree chopped down in A. For example, the stratum, or layer, in which an artifact is found in an ancient structure may make it clear that the artifact was deposited sometime after people stopped living in the structure but before the roof collapsed.

You know that the pot at 3 feet is newer than the other two and the one at 9 is the oldest.
