What is the most accurate method of age determination of the earth?

The best estimate for Earths age is based on radiometric dating of fragments from the Canyon Diablo iron meteorite. From the fragments, scientists calculated the relative abundances of elements that formed as radioactive uranium decayed over billions of years.

Why is radiometric dating more accurate?

Because they do not have the ideal number of neutrons, the isotopes are unstable and over time they will convert into more stable atoms. The rate of isotope decay is very consistent, and is not effected by environmental changes like heat, temperature, and pressure. This makes radiometric dating quite reliable.

Which method of dating fossils gives the most accurate age?

radiometric dating methods 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. Its often much easier to date volcanic rocks than the fossils themselves or the sedimentary rocks they are found in.
