What else can I help you with?
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 is the absolute age of the fossil different from the relative age?
The absolute age of a fossil provides a specific numerical age in years, usually determined through radiometric dating techniques. Relative age, on the other hand, only allows us to determine the fossil's age in relation to other fossils or rocks, based on their layering or sequence in the rock record.
What is the similarity between absolute ans relative dating?
It is the method of descovering the methodof the age of something... I think it is the age of the fossil u are trying to find out
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
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.
What is the true age of a rock or fossil?
The method used will be determined by the rock type, but the age of a rock will be determined by a determination of the amount of decay of a radioactive isotope, either contained in the rock, or in a geologic layer of rock coinciding with a fossil.
How do you tell how old a fossil is by the rock layer?
You can determine the relative age of a fossil by looking at the position of the fossil in the rock layers. The closer a fossil is to the surface, the younger it is relative to fossils found deeper in the layers. To determine the absolute age of a fossil, scientists use radiometric dating techniques on the surrounding rocks to determine the age of the rock layer the fossil is found in.
How can index fossils be used to date rock?
Because if you know how old the fossil is, and you find the fossil inside a rock, you know that rock has a maxium age corresponding with the age of the fossil.
Does Absolute age examines the position of rocks in a sequence?
No, absolute age determines the actual age of a rock or fossil through various dating techniques like radiometric dating. It does not focus on the position of rocks in a sequence but rather provides a specific numerical age.
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
Definition of absolute dating?
age of a rock unit in number of years before present (numerical age).
What two things must scientist measure to find the absolute age of a rock?
scientists use carbon14 and potassium argon to find absolute age of rock
