Edit Answer by Kyle Peters. Relative dating is the science determining the relative order of past events, without necessarily determining their absolute age Absolute dating is the process of determining an approximate computed age in archaeology and geology. Was this answer useful? In PaleontologyFossils. The law of superposition states that layers of undeformed moved or changed sedimentary rock are deposited so that each layer is younger than the layers below it and older th … an the layers above it.

This law gives us the RELATIVE age of fossils, but not the absolute age. Uranium's Half-Life is about 4. Explain why both absolute dating and relative dating are used to determine the age of fossils cannot determins carbon dating on rocks because they were never living things, and did not inhale carbon from the atmosphere. How do you find a fossil's absolute age? The absolute age or direct dating of a fossil is determined by knowing the age of the surrounding rock.

The most common way is by ra … diometric dating, a method that relies on the natural radioactivity of certain elemental isotopes. Different isotopic elements-such as uranium, rubidium, argon, and carbon-have varying but constant rates of radioactive decay. This constancy provides a "radiometric clock," allowing scientists to analyze rock samples and measure the relative ratios between the "parent" and "daughter" isotopes. The ratios reveal the age of the explain why both absolute dating and relative dating are used to determine the age of fossils layer, and thus, the age of the associated fossil.

As with many scientific measurements, although the method is called "absolute," the dates are not exact and there is room for potential errors. Relative compares the age of one event with that of another. Absolute determines the actual age of the event. Earth and planetary sciences, relatiev and mineral collecting.

The Principle of Superposition argues that rock layers towards the top are younger than those at the bottom. This was the principal technique used in the early days. Fossils … have discontinuities - a group fossilss appear, and after a time will vanish again.

But very similar fossils appear around the world at the same time. This subject paleontology, has good records, and a newly fossjls fossil can usually be identified by comparison with the paleontological record. Today of course, radiometric dating is used very widely to determine the age of both rocks themselves, and of fossils.
