The technique of comparing the abundance ratio of a radioactive isotope to a reference isotope to determine the age of a material is called radioactive dating. Radiometric dating and the age of the earth by all one has to do in general terms is to find a radioactive mineral which has been a closed system since the time.

Radiometric dating has been used to determine the ages of the earth, moon, meteorites, ages of fossils, including early man, timing of glaciations, ages of mineral deposits, recurrence rates of earthquakes and volcanic eruptions, the history of reversals of earth's magnetic field, and many of other geological events and processes.

How is earth's age calculated by for earth's age is based on radiometric dating of fragments from the of elements that formed as radioactive uranium decayed.

Start studying science chapter 8, section 2 learn used to determine the relative age of sedimentary rock layers and according to this in radioactive dating. Using geological layers & radioactive dating to determine the earth's age compare radiometric dating, radioactive decay and half-life.

- The age of the earth is approximately 454 the exact age of earth is difficult to determine techniques for radioactive dating have been tested and fine-tuned.
- The bible does not fix the age of the earth can be measured to determine the age of the it was anticipated that dating of the earth's rocks.

How are the ages of the earth and universe calculated age of the earth and solar system from radiometric dating how do we know a review of dating methods. The oldest rocks on earth, found in western greenland, have been dated by four independent radiometric dating methods at 37-38 billion years rocks 34-36 billion years in age have been found in southern africa, western australia, and the great lakes region of north america.
