Carbon14 dating (isotopic dating)
Fossils in rock layers can be used for relative dating, where older fossils are found in lower layers and younger fossils in higher layers. By comparing the fossils in different layers to known fossil sequences, scientists can estimate the age of the rocks. Fossils provide a timeline of life on Earth and can help determine the relative ages of rock layers.
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)
They studied fossils and applied the principle that old layers of rock are below young layers! -
Index fossils are used to determine the relative age of rock layers. By studying the presence of these distinct fossils in different layers of rock, geologists can identify the relative age of the rocks and correlate them with other rock layers in different locations.
Sedimentary rocks, which form in layers over time, are most likely to contain fossils that can be used to establish relative dates. Fossils found in these rocks provide a record of the organisms that lived at specific times in Earth's history, allowing scientists to determine the relative age of the rock layers.

Scientists can use sedimentary rock to determine a fossil's relative age by examining the layers in which the fossil is found. The principle of superposition states that in an undisturbed sequence of sedimentary rock layers, the oldest layer is at the bottom and the youngest layer is at the top. By identifying the layer in which the fossil is located, scientists can approximate its relative age compared to other fossils and rock layers.
fossils can be used to determine the relative age of rock layer by using the classification of fossils to find the relative ages of rocks in which fossils are found. :] hoped i helped you out.

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.

Index fossils are used, and are of significant importance in finding the relative age of rock.

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.

Scientists use the relative amount of stable and unstable isotopes in an object to determine its age.
