Most scientists and many christians believe that the radiometric dating methods prove that the earth is 45 billion years old the textbooks speak of the radiometric dating techniques and the dates themselves as factual information.
Absolute dating is used to determine a precise age of a rock or fossil through radiometric dating methods this uses radioactive minerals that occur in rocks and fossils almost like a geological clock.
The geologic column is the older of the two dating methods employed by scientists to determine the age of the earth basically this is how it works earths many rock layers contain billions of fossils.
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.
dating methods in science strata fossils and age of the earth it presents many links to articles about radiometric dating and the age of the earth however the development of more precise dating methods such as radiocarbondating and dendrochronology has meant that that aspect of pollen analysis has faded away.
Thus the ages of the earth the moon and meteorites as measured by different methods represent slightly different events although the differences in these ages are generally slight and so for the purposes of this chapter they are here treated as a single event.
