By measuring the amount of Uranium contained within the specific rock/fossil. Uranium-238's Half-Life is about 4.47 billion years, So each 4.47 billion years, the amount of Uranium is reduced by half. If the accepted amount of Uranium for a time period is 25%, and the sample contains 12.5%, then it is twice as old as that time period. Scientists cannot use carbon dating on rocks because they were never living things, and did not inhale carbon-14 from the atmosphere.
Radiometric dating of igneous rocks that relate to the sedimentary rock
Scientists find the absolute age of fossils and rocks through radiometric dating techniques such as carbon-14 dating for more recent samples, and methods like uranium-lead dating for older samples. Rock correlations involve comparing the rock layers in different locations to establish their relative ages based on the principle of superposition and the identification of index fossils.

Scientists determine the age of a fossil in rock layers primarily through two methods: relative dating and absolute dating. Relative dating involves examining the position of the fossil within the rock layers, using the principle of superposition, where deeper layers are older than those above them. Absolute dating, often through radiometric dating techniques, measures the decay of radioactive isotopes within the rocks to provide a more precise age. By combining these methods, scientists can establish both the relative and absolute ages of fossils.

Scientists use radioactive isotopes in rocks to calculate their absolute age through a process called radiometric dating. By measuring the ratio of parent isotopes to daughter isotopes in a rock sample, scientists can determine how much time has passed since the rock formed. The rate of decay of the parent isotope into the daughter isotope provides a clock that allows scientists to calculate the rock's age.
The age of the rock. By measuring the amount of parent and daughter isotopes in a rock sample and knowing the half-life of the radioactive element, scientists can calculate the age of the rock.

Relative age is the age of a rock relative to the rock layers around it, absolute age is a rock's exact age.

The absolute age of a rock can be determined through radiometric dating methods, such as carbon dating or uranium-lead dating. These methods rely on the known rates of decay of radioactive isotopes within the rock to calculate how long it has been since the rock formed. By measuring the ratios of parent and daughter isotopes, scientists can determine the rock's absolute age.

They take samples and experiment on them and look at the samples with microscopes. The experiments can then show them the age of the rock. They say "how old are you mr rock" then the rock will say its ages ░░░░░▄▄▄▄▀▀▀▀▀▀▀▀▄▄▄▄▄▄░░░░░░░ ░░░░░█░░░░▒▒▒▒▒▒▒▒▒▒▒▒░░▀▀▄░░░░ ░░░░█░░░▒▒▒▒▒▒░░░░░░░░▒▒▒░░█░░░ ░░░█░░░░░░▄██▀▄▄░░░░░▄▄▄░░░░█░░ ░▄▀▒▄▄▄▒░█▀▀▀▀▄▄█░░░██▄▄█░░░░█░ █░▒█▒▄░▀▄▄▄▀░░░░░░░░█░░░▒▒▒▒▒░█ █░▒█░█▀▄▄░░░░░█▀░░░░▀▄░░▄▀▀▀▄▒█ ░█░▀▄░█▄░█▀▄▄░▀░▀▀░▄▄▀░░░░█░░█░ ░░█░░░▀▄▀█▄▄░█▀▀▀▄▄▄▄▀▀█▀██░█░░ ░░░█░░░░██░░▀█▄▄▄█▄▄█▄████░█░░░ ░░░░█░░░░▀▀▄░█░░░█░█▀██████░█░░ ░░░░░▀▄░░░░░▀▀▄▄▄█▄█▄█▄█▄▀░░█░░ ░░░░░░░▀▄▄░▒▒▒▒░░░░░░░░░░▒░░░█░ ░░░░░░░░░░▀▀▄▄░▒▒▒▒▒▒▒▒▒▒░░░░█░ ░░░░░░░░░░░░░░▀▄▄▄▄▄░░░░░░░░█░░ TROLL
