Since each of these layers seems so specialized it is easy to conclude that one type of creature gave rise to the next type of creature over the course of whatever time it took to form the various layers between them.

We can see how do deal with this if we take a particular case. For example the amount of Rb in mantle rocks is generally low, i.e. The mantle thus has a low If these two independent dates are the same, we say they are concordant.

This is an informational tour in which students gain a basic understanding of geologic time, the evidence for events in Earth’s history, relative and absolute dating techniques, and the significance of the Geologic Time Scale.

Many of the layers also show a certain specialization.

Some layers contain mostly fish fossils while others contain land-dwelling creatures such as dinosaurs.

Diamond is the hardest substance known, so its interior should be very resistant to contamination.

Diamond requires very high pressure to form—pressure found naturally on earth only deep below the surface.

The Triceratops brow horn was excavated in May 2012 and stored at the Glendive Dinosaur and Fossil Museum.

The Museum, which has since 2005 been in cooperation with the Paleochronology Group, a team of consultants in geology, paleontology, chemistry, engineering, and education, sent a sample of the outer portion of the Triceratops brow horn to Head of the Paleochronology Group Hugh Miller, at his request, in order to carry out Carbon-14 dating.

C at all if they really were over a billion years old, yet the radiocarbon lab reported that there was over 10 times the detection limit.

Thus they had a radiocarbon ‘age’ far less than a million years!

For most scientists all of this seems so obvious that it is difficult to question.
