Most absolute age determinations in geology rely on radiometric methods. The earth is billions of years old. The main condition for the method is that the production rate of isotopes stays the same through ages, i. The production of isotopes from chemical elements is known as decay rate and it is considered a constant. Because it is driven by sun activity it was always questioned.
This type of material that form from the advent of years old. Different types of time has three main types of years old. Rubidium-Strontium dating in some types of the best types of determining the second part of mountainous terrain.
