Compare relative dating and chronometric dating

These are called relative and absolute dating techniques.

Absolute dating, also called numerical dating, arranges the historical remains in order of their ages.

It is based on the concept that heated objects absorb light, and emit electrons. A Venn diagram depicts both dating methods as two individual sets.

The area of intersection of both sets depicts the functions common to both.

The changes in this content help determine the relative age of these fossils.

Dendrochronology: Each tree has growth rings in its trunk.

This technique dates the time period during which these rings were formed.

Thermoluminescence: It determines the period during which certain object was last subjected to heat.

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.

The amount of fluorine absorbed indicates how long the fossil has been buried in the sediments.➤ It determines the age of a rock/object using radiometric techniques.➤ Absolute dating is quantitative.➤ This technique helps determine the exact age of the remains.➤ It is more specific than relative dating.➤ Absolute dating is expensive and time-consuming.➤ It works best for igneous and metamorphic rocks.
