Difference between relative dating and radioactive dating

According to the laws of superposition, a strategic layer that is higher has been deposited more recently.The oldest strata are at the bottom of the sequence.By learning how relative and radiometric dating methods work, you can better understand how science uncovers the history of our world.

Comparing the fluorine content of two or more fossilized bones found at the same site can therefore show which are older and which are more recent.For example, based on the primate fossil record, scientists know that living primates evolved from fossil primates and that this evolutionary history took tens of millions of years.By comparing fossils of different primate species, scientists can examine how features changed and how primates evolved through time.According to the 2009 edition of "Essentials of Physical Anthropology," relative dating methods rely on the comparison of two or more things to establish a relative age. One of the main methods of relative dating, stratigraphic dating uses the depth at which something is found to determine its relative age.For example, if two fossils are found at the same site, but at different depths, scientists assume that the fossil found at the greater depth is older. Stratigraphic dating is based on the tendency of lower strata (layers) of rock to be older than higher strata.
