Numerical age dating
Absolute dating, also called numerical dating, arranges the historical remains in order of their ages.
Whereas, relative dating arranges them in the geological order of their formation.
Fluorine dating: Bones from fossils absorb fluorine from the groundwater.
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.
Amino acid dating: 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.
Stratigraphy: 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.
Provide an idea of the sequence in which events have occurred.2.This Science Struck post enlists the differences between the absolute and relative dating methods.Geological specimens that are unearthed need to be assigned an appropriate age.To find their age, two major geological dating methods are used.These are called relative and absolute dating techniques.
