∙ 13y agoEverything has what is called a half-life, it is the time in which a substance, such as carbon halves in quantity. All life forms have a set ratio of carbon to other substances in their bodies and by seeing how much this carbon has depleted they can see how many years have gone by since death (the carbon is replenished while alive so the fossil can only be dated after death in this way).

An isotope like carbon-14 can be used to date dead organisms by counting the atoms with a machine.
What are two ways to date fossils?
Radio-carbon dating is one, carbon 14 changes to carbon 13 over time, scientists measure how much carbon 14 is left in a fossil to determine how old it is.
Which isotope is used to date ancient such as fossils?
The isotope of carbon is used to date the ancient fossils. Since every living creature had organic matter and carbon is an integral part of that organic matter, it is conventional to use carbon isotope.
Radioactive dating enables geologist to determine what?
The age of rocks can be determined by radioactive dating.
Radioactive dating of fossils depends on the decay of what?
plants
Which type of dating provides an absolute age for a given fossil describe how this is done?
I think it's Radioactive dating, I've been reading for my homework and I can't seem to find carbon dating anywhere in the chapter which I've reread about 3 times so I'm going to assume its radioactive because relative dating is the estimation of a fossils age compared with other fossils.
What radioactive carbon isotope is used in dating fossils?
Carbon-14.
What are two ways to date fossils?
Radio-carbon dating is one, carbon 14 changes to carbon 13 over time, scientists measure how much carbon 14 is left in a fossil to determine how old it is.
How many neutrons does carbon has when the radioactive nuclide used in dating fossils?
9
What two ways do scientist use fossils to determine the environmental changes?
its radioactive dating and relative dating
What are two ways geologists determine the age of fossils?
The two methods are "RELATIVE DATING" and "ABSOLUTE DATING". :)
Is stratigraphic dating accurate for dating fossils?
Carbon dating and radioactive dating are more effective, assuming those arn't the same thing. =]
Which isotope is used to date ancient such as fossils?
The isotope of carbon is used to date the ancient fossils. Since every living creature had organic matter and carbon is an integral part of that organic matter, it is conventional to use carbon isotope.
How do you tell which fossils are older?
Fossils found in deeper rock layers are typically older than those found in shallower layers. Scientists also use methods like radiometric dating to determine the age of fossils based on the decay of radioactive isotopes present in the fossils. Additionally, studying the index fossils that are typically associated with specific time periods can help determine the relative age of fossils.
What is a researcher who uses carbon dating?
A researcher who uses carbon dating is typically an archaeologist, anthropologist, or geologist. Carbon dating is a method used to determine the age of organic materials by measuring the decay of radioactive carbon isotopes. This dating technique is commonly applied to artifacts, fossils, and other remains to establish their chronology.
Radioactive dating enables geologist to determine what?
The age of rocks can be determined by radioactive dating.
Could scientists use carbon dating to determine the age of hominids?
Yes, scientists can use carbon dating to determine the age of hominid fossils. Carbon dating relies on measuring the amount of carbon-14 present in a sample to estimate its age. However, carbon dating is typically used on organic materials up to around 50,000 years old, so other dating methods may be necessary for older hominid fossils.
What is used to determine the age of organic remains?
Carbon dating is commonly used to determine the age of organic remains by analyzing the ratio of carbon isotopes in a sample. By measuring the decay of radioactive carbon-14 in relation to stable carbon-12, scientists can estimate the age of the organic material.
