Relative age dating vs absolute age dating

Techniques such as radioactive dating, including carbon dating, focus more on the absolute age of an object.

explain the difference between relative and absolute age dating and describe how the two methods would be used to complete one another in a case where a lava flow that can be dated using radioactive decay methods is both overlain and underlain by sediments with fossils The difference between absolute age and relative age is that; Absolute age: is the EXACT (or absolute) age of an animal, fossil, person, etc. Relative age: is the RELATION of the age comparing to something else, not the exact age. Example: Fossil is anywhere from 5,000 to 8,000 years old.

As far as describing the method with the lava and whatever, I don't know how to answer the second party, really.

Some scientists prefer the terms chronometric or calendar dating, as use of the word "absolute" implies an unwarranted certainty of accuracy.

For example, if an area used for trash has modern refuse in it such as CDs and computers, and the layer underneath has cans made of tin, then it is safe to say the layer of tin cans have a greater relative age than the layer with modern refuse.

Though relative dating can only determine the sequential order in which a series of events occurred, not when they occurred, it remains a useful technique.

Relative dating by biostratigraphy is the preferred method in paleontology and is, in some respects, more accurate.

In archaeology, absolute dating is usually based on the physical, chemical, and life properties of the materials of artifacts, buildings, or other items that have been modified by humans and by historical associations with materials with known dates (coins and written history).
