Why can relative dating be used only to estimate the age of a fossil?
by comparing its placement with that of fossils in other layers of rock
What does comparing organisms in the fossil record provide evidence for?
Comparing organisms in the fossil record providesevidence that organisms have changed over time
What fossil used to compare the relative ages of fossils?
An index fossil. An index fossil's age is known, allowing scientists to know the relative age of other fossils based on their position relative to the index fossil. (Ex. If a fossil is deeper in the earth, it is older than the index fossil)
When you know the relative age of a fossil what else do you know about it?
the relative age of the rock where it was found.
What types of dating estimates the age of a rock or fossil?
The rough estimating of the age of a fossil or rock containing fossils is called relative dating, and is based on the position of the rock or fossil in undisturbed sedimentary strata which contains what are called 'index fossils', fossils that only appear in specific geologic time periods.
Why can relative dating be used only to estimate the age of a fossil?
by comparing its placement with that of fossils in other layers of rock
How the relative age of a fossil is determined by studying layers of rock?
It is determined because in layers of rocks the fossils are found so the layers of rocks give information to the scientist about the age of a fossil so like that the relative age of a fossil is determined.
Is a fossil a relative or absolute time?
It depends. If you are comparing it to something then it is relative. But if your give it a specific age/year, then it is absolute. ex. Relative: The fossil is younger than the shale. Absolute: The fossils is 1000 years old. *note; even if the age is wrong it would still be classified as absolute time
Is a way to determine the age of a fossil by comparing the number of stable isotopes to the number of unstable isotopes using a known half life?
relative dating

relative dating
What does comparing organisms in the fossil record provide evidence for?
Comparing organisms in the fossil record providesevidence that organisms have changed over time
What are the two ways to date a fossil?
Radioactive isotope dating (potassium, argon) and relative dating, comparing with fossils of the same characteristics with known dates. Particularly if they are known to be 'zone fossils'
To compare the relative ages of fossils scientists sometimes use an easily recognized species called?
To compare the relative ages of fossils, scientists use an early recognized species called an index fossil. An index fossil must have existed for a short period time and must have covered a wide geographical range.

An index fossil. An index fossil's age is known, allowing scientists to know the relative age of other fossils based on their position relative to the index fossil. (Ex. If a fossil is deeper in the earth, it is older than the index fossil)
What is the relative age of a fossil starfish?
the relative age of the rock where it was found.
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.
What do geologists use to determine the relative ages of a rock?
Relative dating refers to the process of determining the age of a rock, feature, or fossil by comparing it to the rocks around it. To use relative dating, you need to look at the order each rock layer was deposited.
