What radioactive technique is used to determine the age of fossils? The radioactive technique of radiometric dating is used to determine the age of fossils. This is a way to measure the proportions of a daughter isotope and the parent radioisotope of some element trapped inside a rock since the time the rock formed. A radioisotope is a form of an element with an unstable nucleus. Radioactive atoms decay, or lose energy and subatomic particles until they reach a more stable form. It is not possible to predict the exact instant of one atom's decay, but a predictable number of an isotope's atoms will decay over a period of time. Like the ticking of a perfect clock, the characteristic rate of decay for each isotope is constant. In other words, changes in pressure, temperature, or chemical state do not alter it. Radiometric dating doesn't work for sedimentary rock. It works for volcanic rock or ashes, which hold the most fossils. The ratio of carbon 14 to carbon 12 is used to date recent fossils that still contain some carbon. The only way to date older fossils is to determine their position relative to any volcanic rocks in the same area. This dating method has an error factor of less than 10 percent.

What is radioisotopic dating and how is it used to determine the age of rocks and fossils?
Radioisotopic dating is a method used to determine the age of rocks and fossils by measuring the decay of radioactive isotopes within them. By analyzing the ratio of parent isotopes to daughter isotopes, scientists can calculate the age of the sample. This technique is based on the principle that radioactive isotopes decay at a constant rate over time, allowing researchers to estimate the age of the material.
What is radioactive dating and how is it used to determine the age of rocks and fossils?
Radioactive dating is a method used to determine the age of rocks and fossils by measuring the decay of radioactive isotopes within them. This process relies on the principle that certain isotopes decay at a known rate over time, allowing scientists to calculate the age of the sample based on the amount of remaining radioactive isotopes.

What is the radiometric dating formula used to determine the age of rocks and fossils?
The radiometric dating formula used to determine the age of rocks and fossils is based on the decay of radioactive isotopes. One common formula is the equation for radioactive decay: N N0 e(-t), where N is the amount of radioactive isotope remaining, N0 is the initial amount of the isotope, is the decay constant, and t is the time elapsed.
What is the use of measuring the activity of a radioactive isotope in a sample to determine its age?
Measuring the activity of a radioactive isotope in a sample allows scientists to determine the amount of time that has passed since the sample was formed. By comparing the current activity of the isotope to its original activity, scientists can calculate the age of the sample, a technique commonly used in radiometric dating to estimate the age of rocks, fossils, and archaeological artifacts.

How is carbon dating used to determine the age of dinosaur fossils?
Carbon dating is not typically used to determine the age of dinosaur fossils because dinosaurs lived millions of years ago, beyond the range of carbon dating which is effective up to about 50,000 years. Instead, other methods like radiometric dating are used to determine the age of dinosaur fossils by measuring the decay of radioactive isotopes in the fossils.

Instead, scientists use other methods like radiometric dating, such as uranium-lead dating or potassium-argon dating, to estimate the age of dinosaur fossils. These methods rely on the decay of radioactive isotopes in the fossils to calculate their age.
What radioactive carbon isotope is used in dating fossils?
Carbon-14.
What two methods are used to determine the age of a rock?
The two methods are relative dating and radioactive dating for fossils. I think it's the same for rocks.
