Is dendrochronology absolute or relative dating

Relative techniques are of great help in such types of sediments.➤ It determines if an object/event is younger or older than another object/event from history.➤ Relative dating is qualitative.➤ This technique helps determine the relative age of the remains.➤ It is less specific than absolute dating.➤ Relative dating is comparatively less expensive and time-efficient.➤ It works best for sedimentary rocks having layered arrangement of sediments.The following are the major methods of relative dating.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.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.

Geological specimens that are unearthed need to be assigned an appropriate age.Radiometric dating: 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.The relative dating techniques are very effective when it comes to radioactive isotope or radiocarbon dating.However, not all fossils or remains contain such elements.

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