What isotope is best for dating very old rocks?
Uranium
What isotope is used to determine age of bone?
carbon dating... i think i just learned this in grade 10 chem this week haha
Which dating technique would be best for a volcanic rock containing uranium?
Radiometric dating based on the decay of the uranium.
What is the similarity of radioactive isotope and radioactive dating?
Radioactive isotopes are used for radioactive dating. For example, you would use radioactive isotope Carbon-14 to date anything under 70,000 years that was once living. Radioactive isotopes decay from their parent isotope to daughter isotope at a constant rate (under any circumstances). The rate at which a parent isotope decays to its daughter isotope is considered one half life. Carbon-14 has a half life of 5730 years and its daughter isotope is Nitrogen-14. In order to determine how old something is you have to find out how much of the parent isotope is present in relation to the daughter.
How can we determine the age of ancient objects and rocks?
Through Radiocarbon dating, the age of an object can be determined by using the properties of radiocarbon, a radioactive isotope of carbon. This method was invented by Willard Libby in the late 1940s.
What isotope is best for dating very old rocks?
Uranium
The characteristic of the radioactive isotope uranium-238 that makes this isotope useful for accurately dating the age of a rock is the isotope's BLANK?
constant half-life
Would you use uranium 235 or thorium 232 to date a sample that was about million years old?
Uranium dating is recommended. Thorium dating (but with the isotope 230Th, not with the isotope 232Th) is recommended to minerals old of up to 500 000 years.
Why is a uranium isotope often used rather than 14C in radiometric dating to determine the age of earth?
The isotope carbon 14 is used only for organic materials (or objects contaminated with organic materials); also carbon 14 dating is applicable only to short periods of time.
Which isotope would you use the estimate something that was about 1 million years old?
The method of uranium-lead dating.
If the fossil is to old to use uranium 235 dating?
Uranium dating methods were not used for fossils dating.
What is the use of measuring the activity of a radioactive isotope in a sample to determine its age?
radioactive dating
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.
What isotope is used to determine age of bone?
carbon dating... i think i just learned this in grade 10 chem this week haha
What is good about uranium dating?
Uranium dating is very useful to evaluate the age of rocks and minerals.
Which of the following terms describe the process that is used to determine the age of an object by measuring the amount of a certain radioisotope remaining in that object?
The general term is "radiometric dating. If the isotope is carbon, then it is "carbon dating"
Which dating technique would be best for a volcanic rock containing uranium?
Radiometric dating based on the decay of the uranium.
