The basic idea is to measure the amount of the radioactive isotope, and of one or more of its decay products. The older the rock, the larger the percentage of the original isotope that decayed - so the ratio between the original isotope and the decay product changes over time.
What else can I help you with?
Geologists determine the absolute age of rocks using?
Geologists determine the absolute age of rocks using radiometric dating techniques, such as carbon dating or uranium-lead dating. These methods rely on measuring the proportions of radioactive isotopes and their decay products in the rocks to calculate how long ago they formed.
Does radioactive dating tell the relative age of rocks?
Radioactive dating techniques, such as radiocarbon dating or uranium-lead dating, provide an absolute age for rocks by measuring the decay of radioactive isotopes within them. This helps determine the actual age of rocks rather than their relative age.
Why is radioactive decay used to determine the absolute ages of rocks?
**this happens because it does. is a common answer i receive but is not true. BUT the answer IS that radioactive decay is used to determine the ABSOLUTE age of rocks because it is more accurate, and because when you put radioactive decay and you put a rock there, you see a process going on. correct me if I'm wrong but i believe that using this is receive don't listen to what i say below: When you take radioactive material, and you put a solid in there, what happens? COMBUSTION! this is caused by a CHEMICAL REACTION. so common sense tells me that when you put radioactive decay to determine a rocks absolute age, its common knowledge that they use it for accuracy, and they take the age and see how old it (the rocks) are. that's how they know the age of rocks. (look in your every day science book it should say) hope this helped :3 :D **

What method do geologists use to determine the absolute age of rocks?
Radioactive dating is used to determine the absolute ages of rocks. By Jennifer Palos
How does a geologist determine absolute age?
Geologists determine absolute age by using radiometric dating techniques that involve measuring the decay of radioactive isotopes in rocks or minerals. By analyzing the ratio of parent isotopes to daughter isotopes in a sample, geologists can calculate the absolute age of the rock formation. This method provides a numerical age in years for the rock layer or mineral.
What does radioactive dating enable geologist to determine?
It helps determine the absolute ages of rocks
What does radioactive dating enable geologists determine?
It helps determine the absolute ages of rocks

What method do geologists to determine the absolute age of a rock?
Radioactive dating is used to determine the absolute ages of rocks. By Jennifer Palos
What would you use to do absolute dating of a rock layer?
To do absolute dating of a rock layer, you would typically use radiometric dating methods such as radiocarbon dating, uranium-lead dating, or potassium-argon dating. These methods rely on the decay of radioactive isotopes in the rocks to determine the age of the rock layer.
What are two methods geologist use to determine the age of a rock?
Geologists use relative dating methods to determine the sequence of events that led to the formation of rocks by analyzing the layering of rocks. They also use absolute dating methods such as radiometric dating to determine the numerical age of rocks by measuring the decay of radioactive isotopes within them.
