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.
What else can I help you with?
Which dating method enables scientists to measure or estimate the absolute age of sedimentary rock?
Radiometric dating of igneous rocks that relate to the sedimentary rock
How do scientists find the absolute age of fossils and rock correlations?
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.
Is radioactive decay used to find the absolute age of a rock?
its not from radioactivity its from carbon dating
When do scientists use both radioactive dating and relative dating to find the age of a rock?

How is the absolute age of a rock expressed?
The absolute age of a rock is expressed in years, providing a specific time frame for when the rock was formed. This is typically determined using radiometric dating techniques, which measure the decay of radioactive isotopes within the rock. By calculating the ratio of parent isotopes to daughter isotopes, scientists can estimate the time elapsed since the rock solidified. This method allows for precise dating compared to relative age dating, which only determines the sequence of events.
What two things must scientist measure to find the absolute age of a rock?
scientists use carbon14 and potassium argon to find absolute age of rock

How do scientist use Radioactive Isotopes to find the absolute age of a rock?
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.
A half - life of an element is important for determining the what of a rock?
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.
Which dating method enables scientists to measure or estimate the absolute age of sedimentary rock?
Radiometric dating of igneous rocks that relate to the sedimentary rock
What is the difference between the relative age and absolute age of rocks?
Relative age is the age of a rock relative to the rock layers around it, absolute age is a rock's exact age.
How can the absolute age of a rock be determined?
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.

What method can scientists use to determine the absolute age of a rock?
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
