and is now the principal source of information about the absolute age of rocks and other geological features, including the age of fossilized life forms or the age of the Earth itself, and can also be used to date a wide range of natural and man-made materials.Together with stratigraphic principles, radiometric dating methods are used in geochronology to establish the geologic time scale.

We'll also cover outgassing, gravitational collapse, heat of formation, differentiation, and more! We have over 95 college courses that prepare you to earn credit by exam that is accepted by over 2,000 colleges and universities.You can also take short self-assessment quizzes to test your understanding of these topics.Let our experienced instructors introduce you to the theories explaining the solar system's origin along with the evidence used to support them.We'll cover condensation, uncompressed densities, the ice line, and the condensation sequence.This lesson will define what planetesimals are, how they relate to the solar nebula and protoplanets, and how they interacted with one another to eventually help form the planets in our solar system.Among the best-known techniques are radiocarbon dating, potassium–argon dating and uranium–lead dating.By allowing the establishment of geological timescales, it provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change.After one half-life has elapsed, one half of the atoms of the nuclide in question will have decayed into a "daughter" nuclide or decay product.In many cases, the daughter nuclide itself is radioactive, resulting in a decay chain, eventually ending with the formation of a stable (nonradioactive) daughter nuclide; each step in such a chain is characterized by a distinct half-life.Radiometric dating is also used to date archaeological materials, including ancient artifacts.Different methods of radiometric dating vary in the timescale over which they are accurate and the materials to which they can be applied.
