msn dating gifts - Relative age dating vs radiometric dating

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.

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

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.

To find their age, two major geological dating methods are used.

These are called relative and absolute dating techniques.

Biostratigraphy: An extended version of stratigraphy where the faunal deposits are used to establish dating.

Faunal deposits include remains and fossils of dead animals.
