Relative versus absolute dating


While questionable, it appears as though the living penguins were dated as 8000 years old. If this were not the case, and the decay rate was susceptible to change or was not constant, it would render all ages inaccurate.Relative dating is the more conventional of the two.But what about inorganic objects, such as, say, stone tablets, or rocks?

For example, in decomposing organic bodies - such as an animal carcass - carbon-14, an isotope of carbon, is present.

Overtime, the C-14 atoms give off radiation, and, eventually, transform into nitrogen-14 atoms.

Relative dating is the technique that attempts to roughly determine the age of a fossil using its position or location in relation to other fossils or remains in nearby strata (hence the name, "relative") In other words, to determine the age of a fossil using relative dating, one would look at the stratum the fossil was found in. In fact, it may contain coal or fossil fuels - which take, at the very least, thousands of years to form - that now appear near the very top!

Then, one would compare the fossil's position in the stratum to the position of other nearby index fossils or remains. Such an inconsistency would, logically, confuse geologists in the future if they had no prior knowledge of the St. It is known that volcanic eruptions, such as the one at St. Not only that, but earthquakes and floods can also sometimes shift and mix strata and sediments.

As can be seen, radioactive dating is quite an advanced and sophisticated technique.
