well it mostly depends on the ways and types
1) the logical approach- in this the things (fossils) you find deeper will be more older than the one found on the surface.
2)the constituent study- the method work by calculating the number of isotopes of an element present in the fossil
3)carbon dating - estimating the number of cabon14 isotope.

Why is geologic column an example of circular reasoning?
The geologic column is considered an example of circular reasoning because the ages of the rock layers are primarily determined by the fossils they contain, and the ages of the fossils are determined by the rock layers they are found in. This creates a circular argument where the age of the rocks is used to date the fossils, and the age of the fossils is used to date the rocks.
Can you tell the age of the earth from fossils?
no but you can tell the age of the fossil from the age of the rock around it, you cant tell the age of the earth from fossils is because animals with bones were didnt exist until later in the earth's "life"
Who discovered fossils of ice age animals?
Too many people to count. This year, Robert Taylor found a nearly complete skeleton of a woolly mammoth in Siberia. There a lot of them who discovered fossils of ice age animals. These people are called paleontologists.
What fossils are useful in determining the relative age of rocks?
Index fossils
How do geologists use fossils to determine rocks age what are this fossils called?
Geologists use fossils to determine the age of rocks through a process called biostratigraphy. They identify the specific group of fossils present in the rock layer, known as index fossils, that have a known age range. By comparing the index fossils to a geological time scale, geologists can estimate the age of the rock layer.
How the age of plant and animal fossils is determined?
The age of a plant or animal in a fossil is determined by radiocarbon dating. This means scientists measure the amount of a special type of carbon in the fossil, to determine the date.
Can radiocarbon dating be used to determine the age of pottery?
No. radio carbon dating is only efficient for the fossils of plants or animals. As pottery is an abiotic substance its age cannot be determined by carbon dating

Why do scientist use radioisotopes to find the age of fossils?
Radiometric dating of fossils is not possible beyond roughly 70,000 years. However, when fossils are found in association with strata of volcanic and metamorphic rocks which can be dated radiometrically, a very accurate age of the fossils can be determined.
Can you tell the age of the earth from fossils?
no but you can tell the age of the fossil from the age of the rock around it, you cant tell the age of the earth from fossils is because animals with bones were didnt exist until later in the earth's "life"

What are index fossil and how are they used to determined the absolute age of sedimentary rock?
Index fossils can be used to help determine the relative age of rock layers. Index fossils are from species that only existed for a short time. Index fossils are found in rock layers. Trilobites and Graptolites are index fossils.
Can you make a sentence comparing age of three fossils using ancient?
By definition, we could say all three fossils are 'ancient'. Fossils provide an ancient record of plants and animals.
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.
Why do the La Brea Tar Pit fossils represent a local community of plants and animals that lived in Southern California during the Ice Age?
because, unlike groups of fossils in most sedimentary rocks, the asphalt traps provide a reliable record of animal and plant communities living in one place. --A
Are fossils in physics?
No, fossils are the remaining traces of a plant or animal matter that existed in a past geological age. Physics is the study of all aspects of the interactions between energy and matter.
How do scientists know that the earth has evolved?
From the history that is revealed in rock, particularly in fossils and the age of rock as determined by very precise radiometric dating techniques.
