Radiometric Dating Techniques What are the steps in radiometric dating 1

Radiometric Dating - A Brief Explanation Radiometric dating is the primary dating scheme employed by scientists to determine the age of the earth. Radiometric dating techniques take advantage of the natural decay of radioisotopes. An isotope is one of two or more atoms which have the same number of protons in their nuclei, but a different number of neutrons. Radioisotopes are unstable isotopes: they spontaneously decay emitting radiation in the process -- thus making them radioactive. They continue to decay going through various transitional states until they finally reach stability.

Radiometric Dating — Is It Accurate?

Radiometric dating , radioactive dating or radioisotope dating is a technique which is used to date materials such as rocks or carbon , in which trace radioactive impurities were selectively incorporated when they were formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay. Together with stratigraphic principles , radiometric dating methods are used in geochronology to establish the geologic time scale.

Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks. Radioactive elements decay The universe is full of naturally occurring radioactive elements. Radioactive atoms are inherently unstable; over time, radioactive "parent atoms" decay into stable "daughter atoms. When molten rock cools, forming what are called igneous rocks, radioactive atoms are trapped inside.
