Explain the process of radiometric dating
Radiocarbon dating is one such type of radiometric dating.
A process for determining the age of an object by measuring the amount of a given radioactive material it contains.
There are three general approaches that allow scientists to date geological materials and answer the question: "How old is this fossil?
A fossil can be studied to determine what kind of organism it represents, how the organism lived, and how it was preserved.
The object's approximate age can then be figured out using the known rate of decay of the isotope.
For organic materials, the comparison is between the current ratio of a radioactive isotope to a stable isotope of the same element and the known ratio of the two isotopes in living organisms.
For example, in the rocks exposed in the walls of the Grand Canyon (Figure 1) there are many horizontal layers, which are called strata.
The study of strata is called stratigraphy, and using a few basic principles, it is possible to work out the relative ages of rocks.
