b) Absolute These methods are based on calculating the date of artefacts in a more precise way using different attributes of materials.

This method includes carbon dating and thermoluminescence.

The half-life of C is approximately 5730 years, which is too short for this method to be used to date material millions of years old.

The isotope of Potassium-40, which has a half-life of 1.25 Billion years, can be used for such long measurements.

This approach helps to order events chronologically but it does not provide the absolute age of an object expressed in years.

Relative dating includes different techniques, but the most commonly used are soil stratigraphy analysis and typology.

Most scientists and many Christians believe that the radiometric dating methods prove that the earth is 4.5 billion years old.

Archaeologists have access to various techniques for dating archaeological sites or the objects found on those sites.

Today, many different radioactive elements have been used, but the most famous absolute dating method is radiocarbon dating, which uses the isotope C.

This isotope, which can be found in organic materials and can be used only to date organic materials, has been incorrectly used by many to make dating assumptions for non-organic material such as stone buildings.
