Absolute age is the numeric age of a layer of rocks or fossils.Absolute age can be determined by using radiometric dating. Look at the diagram below and then answer this question: We can date the layers of volcanic ash using radiometric dating, but how can we determine the absolute age of fossil A?

“Radiocarbon Date Calibration Curve” By Howard Morland – Own work based on information from: Reimer, P.

Therefore, absolute dating is a quantitative measurement while relative dating is a qualitative measurement. “Int Cal04 Terrestrial radiocarbon age calibration”.

The main difference between absolute and relative dating is the precision of the measurement. “Absolute Dating.” Science Learning Hub, Available Here2.

You have to date the volcanic layer above and below the fossil layer.

The age of the fossil will be an age range between the ages of the two volcanic layers. The diagram below shows a portion of the Geologic Time Scale.

The four techniques used in absolute dating are radiometric dating, amino acid dating, dendrochronology, and thermoluminescence.

Relative dating is the technique used to determine the age by comparing the historical remaining to the nearby layers.

(Hint: The Law of Superposition might help you.) According to the Law of Superposition newer rock layers form on top of already existing layers.

As more and more layers are deposited, the older rock layers end up at the bottom and the newer ones toward the top. What is the difference between relative and absolute age?

Current scientific evidence shows that the Earth is: c) more than 4 billion years old 2.
