What two methods of radiometric dating are used for rocks more than 10 million years old?
what are two radio active isotopes that are usful for dating rocks that are older than ten million years
What are some of the roles of isotopes?
- Isotopes are used as sources of radiation in medicine, sterilization, nondestructive control, etc.- Isotopes can be used as tracers- Isotopes can be used as energy source- Isotopes are used for radioactive dating- Isotopes are used in chemical analysis- Isotopes are used in many instruments- Isotopes are used as source of nuclear energy in bombs and nuclear reactorsetc.
What method is used to date a rock that is millions of years old?
Radioactive dating, specifically radiometric dating, is used to determine the age of rocks that are millions of years old. This method relies on the decay of radioactive isotopes within the rock to calculate its age. By measuring the ratio of parent isotopes to daughter isotopes, scientists can estimate how long ago the rock formed.
How have scientists used radioactive dating to show that earth is about 4.6 billion years old?
Scientists have used radioactive dating by measuring the decay of radioactive isotopes in rocks to determine their age. By analyzing the ratios of parent and daughter isotopes in samples, scientists can calculate the age of the rocks. This method has shown that the Earth is approximately 4.6 billion years old.
Do isotopes enable scientist to determine th size or age of some rocks?
Isotopes can be used in radiometric dating to determine the age of rocks. By measuring the ratio of parent and daughter isotopes in a rock sample, scientists can calculate how long it has been since the rock formed. This method is particularly useful in dating rocks that are billions of years old.

What gives the age of rocks in years?
The age of rocks in years can be determined through techniques like radiometric dating, which involves measuring the decay of radioactive isotopes present in the rocks. By analyzing the ratio of parent isotopes to daughter isotopes in a rock sample, scientists can calculate its age with high accuracy.\common isotopes used for radiometric dating include carbon-14, potassium-argon, and uranium-lead.

Radiometric dating is done by comparing the ratio of over time?
Radiometric dating is done by comparing the ratio of parent isotopes to daughter isotopes in a sample. By measuring the decay of radioactive isotopes, scientists can determine the age of rocks and minerals. The principle behind radiometric dating is that as radioactive isotopes decay, they transform into stable daughter isotopes at a predictable rate, which can be used to calculate the age of the sample.

Why is a uranium isotope often used rather than 14C in radiometric dating to determine the age of earth?
Uranium isotopes are used for dating older rocks (billions of years old) because their half-lives are longer than that of 14C. Uranium isotopes like 238U have half-lives in the millions to billions of years, making them ideal for dating Earth's age. 14C, with a half-life of about 5,730 years, is more suitable for dating materials up to around 50,000 years old.
How is carbon dating used to determine the age of dinosaur bones?
Carbon dating is not typically used to determine the age of dinosaur bones 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 bones by measuring the decay of radioactive isotopes in the fossils.
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.
How do you find the half life in carbon dating?
You do not find the half life in carbon dating. The half lives of carbon isotopes are derived by studying their radioactive decay. For carbon dating, the isotope used is Carbon-14, which has a half life of 5,700 years.
What is absloute dating?
Absolute dating is a scientific method used to determine the exact age of an object or material, often expressed in years. This technique utilizes various methods, such as radiometric dating, which measures the decay of radioactive isotopes in rocks or fossils. Unlike relative dating, which only establishes a sequence of events, absolute dating provides a precise age, enhancing our understanding of geological and archaeological timelines. Techniques like carbon-14 dating are commonly employed for organic materials, while other isotopes are used for geological samples.
