Relative Dating and Absolute Dating are two types of such techniques which are under practice to determine the age of the fossils, objects or. Relative Vs. Absolute Dating. Our planet inherits a large number of artifacts and monuments bestowed upon us by older historic civilizations. IV. Relative Dating. V. Absolute Dating; Absolute Dating – • the process of establishing the age of an object by determining the number of.

The oldest dating method which studies the successive placement of layers. It is based on the concept that the lowest layer is the oldest and the topmost layer is the youngest.

An extended version of stratigraphy where the faunal deposits are used to establish dating. Faunal deposits include remains and fossils of dead animals.

This method compares the age of remains or fossils found in a layer with the ones found in other layers. The comparison helps establish the relative age of these remains. Bones from fossils absorb fluorine from the groundwater.

The amount of fluorine absorbed indicates how long the fossil has been buried in the sediments. This technique solely depends on the traces of radioactive isotopes found in fossils.

The rate of decay of these elements helps determine their age, and in turn the age of the rocks.

Physical structure of living beings depends on the protein content in their bodies. The changes in this content help determine the relative age of these fossils. Each tree has growth rings in its trunk. This technique dates the time period during which these rings were formed. It determines the period during which certain object was last subjected to heat.

It is based on the concept that heated objects absorb light, and emit electrons. The emissions are measured to compute the age.

Differentiation Using a Venn Diagram A Venn diagram depicts both dating methods as two individual sets. The area of intersection of both sets depicts the functions common to both.

Take a look at the diagram to understand their common functions. In relative dating, mostly the common sense principles are applied, and it is told that which artifact or object is older than the other one.

Relative Vs Absolute Dating

Most commonly, the ancient factors of the rocks or objects are examined using the method called stratigraphy.

In other words, we can say that the age in the relative dating is ascertained by witnessing the layers of deposition or the rocks. As the word relative tells that defining the object with respect to the other object, it will be pertinent to mention here that actual numerical dates of the rocks or sites are not known in this type of dating.

Other than rocks, fossils are the other most important elements in the relative dating as many organisms have there remain in the sedimentary rocks. This evaluation of the rocks and fossils in the relative dating is known as the biostratigraphy. Advertisement What is Absolute Dating?

Relative Dating vs. Absolute Dating: What's the Difference?

The absolute dating is the technique to ascertain the exact numerical age of the artifacts, rocks or even sites, with using the methods like carbon dating and other. To evaluate the exact age, both the chemical and physical properties of the object are looked keenly. The main techniques used in absolute dating are carbon dating, annual cycle method, trapped electron method, and the atomic clocks. These techniques are more complex and advanced regarding technology as compared to the techniques in practice in the relative dating.

The absolute dating is also sometimes referred as the relative numerical dating as it comes with the exact age of the object.

The absolute dating is more reliable than the relative dating, which merely puts the different events in the time order and explains one using the other. The radiometric dating is another crucial technique through which the exact age can be obtained.

In radiometric dating, the radioactive minerals within the rocks are used to know about the age of the object or the sites.
