Check new design of our homepage! Although both relative and absolute dating methods are used to estimate the age of historical remains, the results produced by both these techniques for the same sample may be ambiguous.

Geological specimens that are unearthed need to be assigned an appropriate age. To find their age, two major geological dating methods are used. These are called relative and absolute dating techniques. Absolute dating, also called numerical dating, arranges the historical remains in order of their ages.

Whereas, relative dating arranges them in the geological order of their formation.

Absolute dating is the process...

The relative dating techniques are very effective when it comes to radioactive isotope or radiocarbon dating. However, not all fossils or remains contain such elements. Relative techniques are of great help in such types of sediments. The following are the major methods of relative dating.

So, how do we know...

The oldest dating method which studies the successive placement of layers. It is based on the concept that the lowest layer is the oldest and the topmost layer is the youngest.

An extended version of stratigraphy where the faunal deposits are used to establish dating. Faunal deposits include remains and fossils of dead animals. This method compares the age of remains or fossils found in a layer with the ones found in other layers.

The comparison helps establish the relative age of these remains. Bones from fossils absorb fluorine from the groundwater. The amount of fluorine absorbed indicates how long the What is absolute dating in terms of fossils has been buried in the sediments. This technique solely depends on the traces of radioactive isotopes found in fossils.

The rate of decay of these elements helps determine their age, and in turn the age of the rocks. Physical structure of living beings depends on the protein content in their bodies. The changes in this content help determine the relative age of these fossils. Each tree has growth rings in its trunk. This technique dates the time period during which these rings were formed. It determines the period during which certain object was last subjected to heat.

It is based on the concept that heated objects absorb light, and emit electrons. The emissions are measured to compute the age.
