What do scientists use to date exact age of fossils?
For relatively recent fossils, dating by carbon 14 is the most accurate method. For older fossils it is necessary to analyse the geological layer in which they are found; fossils located in an undisturbed geological layer of a certain age, are the same age as the layer in which they are found, necessarily.
How do modern scientist determine the age of fossils?
by carbon dating it is testing how much radioactivity is in carbon 14 because radio activity has a half life so how much radio activity is left then they can determine how old it is
Can carbon dating be used on a stone to determine it's age?
It is not possible to carbon date rocks. Carbon 14 dating is based on the absorption of atmospheric carbon by livingthings. When the thing dies it no longer takes in carbon from the atmosphere through processes such as eating or respiration and levels of C14 in the body deplete due to the natural process of radioactive decay. By seeing how much C14 remains it is possible to see how long it has been since that animal died.However there are a range of other dating methods which can be used.
How can you determine accurate ages of rock layers?
Stratigraphic position Age Dating techniques i.e. carbon etc Fossil Assemblage present in rock specimen
What is the method of determining whether a fossil is older or younger than other fossils found in the many layers of sedimentary rock is called what?
relative dating
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.
Carbon 14 is useful for dating fossils that are?
Carbon 14 dating is most useful for dating fossils that are up to 50,000 years old. Beyond this time frame, the amount of C-14 left in the fossil is too minimal to provide accurate dating results.
Can radiocarbon dating be used to determine the age of dinosaur fossils?
No, radiocarbon dating cannot be used to determine the age of dinosaur fossils because the half-life of carbon-14 is too short for dating objects that are millions of years old. Instead, other dating methods like uranium-lead dating or potassium-argon dating are used for dating dinosaur fossils.

How do scientists use Carbon-14 to date fossils?
Carbon-14 is in all living things and decays after it dies. It has a long half life (the time it takes for half a sample to decay into another element) and gives a good estimate as to how old something is. Carbon dating is only effective up to an approximate age of 70,000 years, and is only useful in dating organic matter. Since the vast majority of fossils are much older than this, carbon dating is not particularly useful in dating fossils, but is of great use in archaeology.
How is carbon dating used to determine the age of fossils?
Assuming the word is 'date'; their stratigraphy - their position in the sedimentary sequence, will indicate which are older. [Assuming the fossil bed has not been overturned by earth movements.] Otherwise, various radiometric methods might be used to measure the age, but these are relatively more expensive.

The process of figuring out if an object is older or younger than another?
facebook or carbon dating =]
What is the limite for carbon dating?
About 58,000 years. After that amount of time, there will no longer be enough radioactive carbon in an object to measure. However, other radiometric dating methods can date much older materials.
Does radiocarbon dating determine the age of the earth?
No, radiocarbon dating is used to determine the age of organic materials up to around 50,000 years old. To determine the age of Earth, scientists use other methods like uranium-lead dating of rocks or meteorites, which provide an estimate of about 4.5 billion years.
