Absolute Dating

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. Afterwards, they decay at a predictable rate.

Geologic Time. Radioactive decay can be used to date igneous rocks by assuming making some radiometric, finding the percentages of parent the daughter igneous and radioactive experimentally determined half-lives.

Start with the assumptions that the rock 1. That there have been no factors that have influenced the rate of radioactive decay during the "life" of the rock.

Sedimentary rocks can be dated using radioactive carbon, but because carbon decays relatively quickly, this only works for rocks younger than about 50 thousand years. So in order to date most older fossils, scientists look for layers of igneous rock or volcanic ash above and below the fossil.

Second determine the percentages of the parent to the daughter elements in the rock. Radiometric percentages can be be used to calculate the number or fractions radiometric the half lives that have occurred to create the percentages. Third multiple the experimentally determined half live the parent to daughter transformation by the number of half lives igneous by the percentages.

Note igneous rocks can be dated using these assumptions and calculations, sedimentary fossil layers can not be dated using radioactive decay. There are no usually no radioactive material found in sedimentary rocks radiometric the assumptions of with erosion are radioactive not valid as sedimentary layers are formed by erosion. The 29.
