They would look for evidence of index fossils, those of certain rapidly evolving creatures that lived during a specific time period. This method is called relative dating. For a closer estimation they would be able to date the rock using radiometric techniques that base its age on the degree of isotope decay . This method would reveal the much more specific absolute age.

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 does a geologist determine absolute age?
Geologists determine absolute age by using radiometric dating techniques that involve measuring the decay of radioactive isotopes in rocks or minerals. By analyzing the ratio of parent isotopes to daughter isotopes in a sample, geologists can calculate the absolute age of the rock formation. This method provides a numerical age in years for the rock layer or mineral.
Index fossils allow geologists to?
Index fossils help geologists determine the relative age of rock layers by comparing the fossils found in them to known ages of fossils. By identifying specific index fossils, geologists can correlate rock layers from different locations and help determine the chronological order of events in Earth's history.

Geologists determine the absolute age of rocks using?
Geologists determine the absolute age of rocks using radiometric dating techniques, such as carbon dating or uranium-lead dating. These methods rely on measuring the proportions of radioactive isotopes and their decay products in the rocks to calculate how long ago they formed.

What are index fossils and how are they used to determine the absolute age of sedimentary rocks?
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.
What are index fossils used to determine?
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.
How do geologists use the column?
Geologists use the geologic column to classify layers of rocks and fossils that make up the Earth's crust.
