Cross dating: 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.
When we observe the intersection in this diagram depicting these two dating techniques, we can conclude that they both have two things in common:1.
Provide an idea of the sequence in which events have occurred.2.
Thermoluminescence: 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. A Venn diagram depicts both dating methods as two individual sets.
Different methods have their own limitations, especially with regard to the age range they can measure and the substances they can date.Dendrochronology: Each tree has growth rings in its trunk.This technique dates the time period during which these rings were formed.Determine the age of fossils, rocks, or ancient monuments.Instead, other methods are used to work out a fossil’s age.
