Another absolute dating method is thermoluminescence, which dates the last time an item was heated.
This method includes carbon dating and thermoluminescence.
Radiometric dating, or numeric dating, determines an actual or approximate age of an object by studying the rate of decay of radioactive isotopes, such as uranium, potassium, rubidium and carbon-14 within that object.
Best Answer: Relative dating Before the advent of absolute dating in the 20th century, archaeologists and geologists were largely limited to the use of Relative Dating techniques.
The principle becomes quite complex, however, given the uncertainties of fossilization, the localization of fossil types due to lateral changes in habitat change in sedimentary strataand that not all fossils may be found globally at the same time.
However, the layer of that material will become thinner as the amount of material lessens away from the source.
