No. To find the relative age of a rock, you need to identify the geologic age, the relative time in Earth's history that the rock was formed. This can be done by physical identification of any corresponding index fossil evidence in the rock, or by identifying it with a geological event or rock formation that has been previously been dated.
The Principle of Superposition is a fairly reliable way of determining the older from the younger rock - the older one will usually be at the bottom.
This method for relative determination is often supplemented by searching for fossil evidence - sometimes of pollen fossils.
Radiometric dating relies on measuring the decay rate (the half life) of certain radiogenic elements. Using known chronons such as K-Ar, 14C, Rb-Sr and many others. Each of these have different useful times ranging from a few thousand years, to ages longer than that of the Earth.
Absolute ages can be determined by a comparison of radioisotope levels. The ratio between the parent and daughter isotopes of a particular radioactive substance can yield the rock's absolute age.
Often enough when one clock is available, such as Uranium/Uranium, so are two others--Uranium/Thorium and Potassium/Argon. When all three clocks agree, it is a safe bet the rock's determined age is correct.
They need to determine the amount of radioactive decay of a specific isotope in the rock since its formation.
By the law of superposition.
Relative dating refers to the process of determining the age of a rock, feature, or fossil by comparing it to the rocks around it. To use relative dating, you need to look at the order each rock layer was deposited.
Scientists use sedimentary rock to determine a fossil relative age by studying the rock.
The intrusion is younger than the overlying sedimentary rock.
Relative Dating is the technique used to determine the age of rock deposits by natural forces.
By the law of superposition: Oldest at the bottom and youngest at the top.
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.

If we know the age the respective organism is known to have occupied a certain region in the geologic past we can then correlate that to the rock its fossil was found in and consequently deduce the rock's relative age.
Answer: The age of a rock compared to the ages of the rock layers.

They studied fossils and applied the principle that old layers of rock are below young layers! -
Yes, stratigraphy is a method to determine the relative age of rock strata. Stratigraphy is a branch of geology which studies rock layers.
Stratigraphic position Age Dating techniques i.e. carbon etc Fossil Assemblage present in rock specimen
The principle of superposition states that a rock layer on top of another is younger than the one beneath it. Geologists use the principle of superposition to determine the relative ages of rock layers.
Radioactive dating is used to determine the absolute ages of rocks. By Jennifer Palos
Good question: Geologist use these methods to determine the ages of rocks. The absolute age of the rock and relative age of the rock. Now because the mid ocean ridges are place of divergent where plates move apart, the rock farther away from the ridges are older than the younger ones that are just form close to the ride. This is called relative dating. The absolute dating use Isotopes and radiometric dating meaning they have to have a hand sample to determine this. But I think the best method here for situation like this is the Relative ages of the rocks.
It's age compared to the ages of other rocks.
