What is isotopes accumulate in old uranium bearing rock?
All the isotopes from the decay chains exist in these rocks. The most important are the dangerous isotopes of radium and radon.
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.
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.
How are radioactive isotopes used determine the absolute age of igneous rock?
Answer : When the isotopes decay, scientists can find out how old the rock is depending on the radioactive isotope's half-life. Explanation: Radioactive isotopes are unstable and will decay. For example, when humans die carbon-14 decays. The isotopes will decay into a stable isotope over time. Scientists can tell how old the rock was from looking at the radioactive isotope's half-life, which tells them how long it would take for there to be half the radioactive isotope and half the stable isotope. At the next half-life there will be 25% of the radioactive isotope and 75% of the stable isotope. At the next half life there will be 12.5% radioactive and 87.5% stable. Example: Carbon-14 is a radioactive isotope with a half life of 5,730 years. How old would carbon-14 be when there is 75% carbon-14 in the rock? 75% is half of the time before the half-life, so it would be 2,365 years. Hope this helps. Half life helps scientists find how much the isotope has decayed and the age of the rock.
How old are rocks dated by the uranium-lead method?
The uranium-lead dating method can date rocks that are millions to billions of years old, making it one of the most reliable techniques for determining the age of the Earth and other ancient geological formations. It is particularly effective for dating zircon crystals found in igneous rocks, which can survive geological processes. The method relies on the radioactive decay of uranium isotopes into stable lead isotopes, allowing scientists to calculate the age of the rock based on the ratios of these isotopes.

What is the rock formed as a result of deposits from weathering and erosion?
Sedimentary rock is the rock formed as a result of deposits from weathering and erosion. Sedimentary rock can be millions of years old.

What is the appropriate radioactive isotope to use to estimate the age of a rock from a rock formation believed to be a billion years old?
Uranium-238 (U-238) is an appropriate radioactive isotope to estimate the age of a rock formation believed to be a billion years old. This isotope has a half-life of about 4.5 billion years, making it suitable for dating rocks of such age. By measuring the ratio of U-238 to its decay product, lead-206 (Pb-206), scientists can calculate the age of the rock formation.
Gaseous products of a disintegrating radioactive substance such as thoron or radon?
The gaseous products of a disintegrating radioactive substance such as thoron or radon usually include isotopes of helium or polonium. These isotopes are formed as a result of radioactive decay and are emitted in the form of gas. They can pose a health risk if inhaled, as they are radioactive and can accumulate in the lungs.
Why would the bottom of the sedimentary rock be the oldest?
Because the sediments will accumulate in the sides. Imagine a ball, start covering it with paper, later with aluminum foil, the old part (the ball) will be in the bottom, the not so old part (the paper) will be in middle and the newest part (the aluminum foil) will be outside. Hope you understand.
When was Old Skoöl of Rock created?
Old Skoöl of Rock was created in 2009.
Who old is the rock?
A crystalline rock could be anything from 4,600 million years old to an hour old.
Fossils are most likely found in what rock?
No. They are usually found in sedimentary rock.
