Describe absolute dating and relative dating

These processes result in All of these processes confuse the stratigraphic record.In many cases, however, it is possible to reconstruct the original sequence of strata so that they can be used for relative dating.can be used to tell us whether or not the animals they were from actually lived at about the same time.This relative dating method is based on the fact that there are specific progressive chemical changes in skeletal remains that result from burial underground.(length = 7 mins, 24 secs) The perpetrator of the Piltdown Man hoax may have been uncovered.In the mid 1990's, an old tool kit was found in a dusty backroom of the Natural History Museum in London.

As a result, the amount of fluorine Fluorine analysis can be used only as a relative dating method because the rate of decay and the amount of dissolved minerals in the ground water varies from site to site.

That man was a medical doctor by training and therefore had the necessary skills to carry off the hoax.

He was Sir Arthur Conan Doyle, the author of the Sherlock Holmes detective stories.

As time passes, the organic components of bone (mostly fat) are lost primarily through bacterial action.

Since these components contain nitrogen, there is a progressive loss of that element.
