Typically carbon is used in a technique known as carbon dating. Technically, it is known as Carbon-14 dating. Pretty much all living things are made up of Carbon. When something dies, the Carbon-14 in the organism starts breaking down. Since Carbon-14 disintegrates in a very uniform and predictable way, we can gauge the age by determining the level of Carbon-14 disintegration.

Which isotope can be used as a tracer to study the age of organic material?
Carbon-14
What type of dating uses the properties of atoms in material to determine an object's age?
Radiometric or isotopic dating.
Why can carbon dating not be used to date old knives?
While carbon-14 dating cannot be used to date the knife itself, because it is metal and thus not a once living thing (steel does contain carbon, but this carbon may be from trees or coal and is not easily separated from the iron for testing). However if the knife has a handle made of natural organic material (e.g, wood, bone, antler, ivory) this handle can be carbon-14 dated to obtain an estimate of the age of the knife.
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.
What do scientists use to data the exact age of fossils?
A technique called Radiocarbon dating was (and still is) used. In organic material, such as plants and animals, the amount of a naturally occurring isotope of Carbon, C-14, can be measured. C-14 is gradually depleted in the atmosphere, so the more C-14 is present, the older the fossil is. The amount of C-14 in the atmosphere can be fairly accurately calculated up to 62,000 years ago. When the concentration of C-14 in the fossil is measured, scientists compare it with calculated data from the past, and they make an estimation of a fossils age. An exact age cannot be determined, but this is the most accurate estimation we can produce.
What carbon dating measure?
Carbon dating is used to measure the age of organic material from long ago.
What does carbonating measure?
Carbon dating is used to measure the age of organic material from long ago.
What is the age determined by carbon dating?
The age of organic material up to about 70,000 years.
Carbon dating can be used to measure the age of each the following except?
Carbon dating can be used to measure the age of organic materials.
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.
How is half life used for carbon dating?
Knowing the half life of carbon-14 the age of an artefact containing an organic material can be evaluated.
What can carbon dating be used to date?
Carbon dating can be used to date organic materials, such as wood, bones, shells, and charcoal. It is particularly useful for determining the age of archaeological artifacts and fossils that are up to about 50,000 years old.
What substances show carbon dating?
The element Carbon is in all living things, it is a basic building block for the construction of organic material and measuring the age of material.
Radioactive decay of carbon isotopes can be use for?
to allow the correct amount of oxygen to enter and leave the substance
Which isotope can be used as a tracer to study the age of organic material?
Carbon-14
What was carbon dating used for?
Carbon dating is iused to evaluate the age of organic materials (down to 50 000 years ago).
Could radioactive dating only be used for igneous rocks?
Radioactive dating is only useful in dating igneous and metamorphic rock. Organic material that has not fossilized and does not exceed 70,000 years of age can be dated by Carbon dating techniques. Sedimentary rock can only be dated by its association with igneous and metamorphic rock.
