Early scientific attempts st determining Earth's age gave a number that was around 4.6 billion years old.
<h3>Radiometric dating methods</h3>
The age of rocks can be most determined by radiometric dating.
This process of radiometric dating makes use of two different isotopes of a sample.
It is known that Radioactive isotopes break down within a known amount of time and this enables geologists to determine the age of a sample with the aid of equipment like thermal ionization mass spectrometer.
