It is the difference between sand running out of an hour glass and determining what time it is by how much sand is left. Radioactive decay happens at a steady rate. If you can determine how much of that radioactive isotope ought to have been in a sample at the start and you can measure how much is left, you can tell how much time has passed.

ReneRadioactive decay is the process by which unstable atomic nuclei lose energy or particles, emitting radiation in the form of alpha, beta, or gamma rays. Radiometric dating utilizes the principles of radioactive decay to determine the age of rocks, fossils, or other geological materials by measuring the abundance of certain isotopes and their decay products. Essentially, radioactive decay is the physical process, while radiometric dating is the application of that process to calculate ages.

What is the difference between radio active decay and radio metric dating?
Radioactive decay is the process where unstable isotopes break down into more stable isotopes by emitting radiation. Radiometric dating, on the other hand, is a method used to determine the age of rocks or fossils by measuring the amounts of certain radioactive isotopes and their decay products. Essentially, radioactive decay is the underlying process that radiometric dating relies on to determine the age of a sample.
Why does radiometric dating work to determine the age of rocks and fossils?
Radiometric dating works to determine the age of rocks and fossils by measuring the decay of radioactive isotopes within them. This decay occurs at a constant rate, allowing scientists to calculate the age of the sample based on the amount of remaining radioactive isotopes.
Scientists used radioactive decay to measure what?
Scientists used radioactive decay to measure the age of rocks, artifacts, and archaeological materials. By measuring the amount of radioactive isotopes present in a sample and comparing it to the known half-life of the isotope, scientists can determine how long ago the material formed. This technique is known as radiometric dating and allows researchers to establish the age of objects thousands to billions of years old.
What are three types of radiometric dating?
Three types of radiometric dating are carbon-14 dating, uranium-lead dating, and potassium-argon dating. These methods are used to determine the age of rocks and fossils by measuring the decay of radioactive isotopes into stable isotopes over time.
How does radiometric dating work to determine the age of rocks and fossils?
Radiometric dating measures the decay of radioactive isotopes in rocks and fossils to determine their age. By comparing the ratio of parent isotopes to daughter isotopes, scientists can calculate the age of the sample based on the known rate of decay for that particular isotope.
