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.

∙ 13y agocarbon dating, compares age of carbon particles which develop in fossils with ages of similarly mature carbon atoms to give the date... or something like that.. think may have to do with crystal lattice or wadawada.. i wil pay attention nxt time

What must be true for a fossil organism to be useful as a index fossil?
The absolute age of the index fossil was determine by radioactive dating or another absolute method
Who measures the ratio of unstable to stable atoms in a rock sample to estimate the age of the fossil it contains?
Absolute dating
How do you determine the absolute age of a fossil?
How do you find a fossil's absolute age? The absolute age (or direct dating) of a fossil is determined by knowing the age of the surrounding rock. The most common way is by radiometric dating, a method that relies on the natural radioactivity of certain elemental isotopes. Different isotopic elements-such as uranium, rubidium, argon, and carbon-have varying (but constant) rates of radioactive decay. This constancy provides a "radiometric clock," allowing scientists to analyze rock samples and measure the relative ratios between the "parent" and "daughter" isotopes. The ratios reveal the age of the rock layer, and thus, the age of the associated fossil. As with many scientific measurements, although the method is called "absolute," the dates are not exact and there is room for potential errors.
What do scientists use to determine a fossil's relative age?
Carbon14 dating (isotopic dating)
What does the fossil record provide for paleontologists?
The fossil record provides nothing good for paleontologists.
What must be true for a fossil organism to be useful as a index fossil?
The absolute age of the index fossil was determine by radioactive dating or another absolute method
How does relative dating and absolute dating help scientists assemble a fossil record for an area?
Relative dating is the science determining the relative order of past events, without necessarily determining their absolute age Absolute dating is the process of determining an approximate computed age in archaeology and geology.
How can someone find the absolute age of a fossil?
By using radiometric or radiocarbon dating.
What does relative dating provides?
It provides how old a rock/fossil is compares to the rocks/fossils around them.
What are two ways geologists determine the age of fossils?
The two methods are "RELATIVE DATING" and "ABSOLUTE DATING". :)
Who measures the ratio of unstable to stable atoms in a rock sample to estimate the age of the fossil it contains?
Absolute dating
What radiometric dating tell us?
It tells us the absolute age of something, It is used when scientists want to see how old a fossil is.
What is relative and absolute age?
Absolute- Actual Age of a rock Relative- The age of something compared to other things Relative age does not tell how old something is but tells us in what order events have happened relative- the age of a rock or fossil compared to the surrounding rocks and fossil
How do scientist use radioactive elements to determine the actual age of fossils?
scientist can determine a fossil's age in two ways: relative dating and absolute dating
What information is obtained from radioactive dating?
The age of an object that was once living.
Explain how radiometric dating is used to estimate absolute age?
Radiometric dating is based on the principle that certain isotopes decay at a constant rate over time. By measuring the ratio of parent isotopes to daughter isotopes in a rock sample, scientists can calculate how much time has passed since the rock formed. This method provides an accurate estimate of the absolute age of the rock or fossil.
How is the absolute age of the fossil different from the relative age?
Absolute age is the definite age of a fossil, while relative age is an estimated age according to the sediments and other fossils around the fossil.
