Radiometric and radiocarbon dating
There are different methods of radiometric dating that will vary due to the type of material that is being dated.For example, uranium-lead dating can be used to find the age of a uranium-containing mineral.It works because we know the fixed radioactive decay rates of uranium-238, which decays to lead-206, and for uranium-235, which decays to lead-207.
These two uranium isotopes decay at different rates. The half-life of the uranium-238 to lead-206 is 4.47 billion years.Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.
