Relative dating-comparing fossils related to how old other fossils are in the same sample of rock.
If the rock has been undisturbed, the oldest rock will be at the bottom, therefore, the oldest fossils will also be at the bottom. the youngest rock will be at the top, therefore, the youngest fossils will be at the top.

DevinThe dating technique you are referring to is called relative dating. By studying the position of fossils in rock layers, scientists can determine the relative age of the fossils and the rocks they are found in. This helps in understanding the chronological order of events in Earth's history.

What is isotopic dating and how is it used to determine the age of rocks and fossils?
Isotopic dating is a method used to determine the age of rocks and fossils by analyzing the decay of radioactive isotopes within them. By measuring the ratio of parent isotopes to daughter isotopes, scientists can calculate the age of the sample. This technique is based on the principle that certain isotopes decay at a constant rate over time, allowing researchers to accurately date rocks and fossils.
What radioactive technique is used to determine the age of fossils?
Carbon-14 dating is a radioactive technique commonly used to determine the age of fossils. This technique measures the decay of carbon-14 isotopes in organic materials to estimate how long ago the organism died.
What is radioisotopic dating and how is it used to determine the age of rocks and fossils?
Radioisotopic dating is a method used to determine the age of rocks and fossils by measuring the decay of radioactive isotopes within them. By analyzing the ratio of parent isotopes to daughter isotopes, scientists can calculate the age of the sample. This technique is based on the principle that radioactive isotopes decay at a constant rate over time, allowing researchers to estimate the age of the material.
How fossils can be used to determine the absolute and relative age of a sedimentary rock layer?
Perhaps by carbon dating and by comparing with the evolution and dominance of various organisms in the geological time scale.
An understanding of which of these best enabled scientists to determine the approximate ages of fossils?
The understanding of radioactive decay, specifically carbon dating and other radiometric dating methods, has enabled scientists to determine the approximate ages of fossils by measuring the decay of isotopes within the fossils. This process allows scientists to estimate the age of fossils based on the ratio of isotopes present in the sample.
