how does relative dating show the history of a region
Geologists generally know the age of a rock by determining the age of the group of rocks, or formation, that it is found in. The age of formations is marked on a geologic calendar known as the geologic time scale. Development of the geologic time scale and dating of formations and rocks relies upon two fundamentally different ways of telling time: relative and absolute.
Radiometric measurement is based on the decay of certain elements, the rate of which is a known scientific fact.
Rocks contain what we call "Clocks" these can be minerals which are resistant to weathering such as Zircon. They are used to estimate absolute ages of Geological structures.Using these clocks combined with the Geological events i.e drastic Changes to the earths environment leading especially to extinction of specific animal species eg.Dinasours and the type of Organisms that existed at that time,the geological time scale is born
Plant life could be used to interpret the geologic history of a location.
Relative dating is the process that places geologic events in the proper sequence.
Stratigraphic dating.
The geologic column is the result of the core sample showing layers of artifacts and material. Since some of these can be carbon dated, a relative time period can be established.

relative dating
No. radio carbon dating is only efficient for the fossils of plants or animals. As pottery is an abiotic substance its age cannot be determined by carbon dating

This is called absolute, isotopic, or radiometric dating.

More often used is the term geochronology: dating the formation of rocks in geology.The geochrony of a rock can reveal when a layer of rock was formed.Geologic folding can sometimes confuse the geochrony of a rock formation.
