Relative dating for fossils

Radiocarbon dating involves determining the age of an ancient fossil or specimen by measuring its carbon-14 content.

Carbon-14, or radiocarbon, is a naturally occurring radioactive isotope that forms when cosmic rays in the upper atmosphere strike nitrogen molecules, which then oxidize to become carbon dioxide.

Relative time can not determine the actual year a material was deposited or how long deposition lasted; it simply tell us which events came first.

ANSWER: Relative dating is used to determine the relative ages of geologic strata, artifacts, historical events, etc.

To deal with many of these problems geologists utilize two types of geologic time: relative time and absolute time.

Relative time places events or formations in order based on their position within the rock record relative to one another using six principles of relative dating.

This feature is produced by changes in deposition over time.

Carbon-14 is also passed onto the animals that eat those plants.After death the amount of carbon-14 in the organic specimen decreases very regularly as the molecules decay.The most obvious feature of sedimentary rock is its layering.Although there might be some mineral differences due to the difference in source rock, most sedimentary rock deposited year after year look very similar to one another.This means that a quartz sandstone deposited 500 million years ago will look very similar to a quartz sandstone deposited 50 years ago.
