Apply different dating methods to calculate the age of earth
The age of the earth is 454 177 005 billion years 454 215 10 9 years 177 1 this age may represent the age of the earths accretion of core formation or of the material from which the earth formed.
The oldest rocks on earth found in western greenland have been dated by four independent radiometric dating methods at 3738 billion years rocks 3436 billion years in age have been found in southern africa western australia and the great lakes region of north america.
Critical to this resolution were improved methods of dating which incorporated advances in mass spectrometry sampling and laser heating the resulting knowledge has led to the current understanding that the earth is 455 billion years old that takes us to.
In the 1920s earths age crept up toward 3 billion years making it for a time even older than the universe which was then estimated to be about 18 billion years old.
age of the earth and solar system from radiometric dating in your high school science classroom you may have seen a large poster of the periodic table hanging on the wall the periodic table shows the types of atoms that make up the world around us.
Nevertheless scientists have been able to determine the probable age of the solar system and to calculate an age for the earth by assuming that the earth and the rest of the solid bodies in the solar system formed at the same time and are therefore of the same age.
Finally correlation between different isotopic dating methods may be required to confirm the age of a sample for example the age of the amitsoq gneisses from western greenland was determined to be 36 177 005 million years ago ma using uraniumlead dating and 356 177 010 ma using leadlead dating results that are consistent with each other.
