Absolute vs relative dating methods
The most common form of relative dating is called stratigraphic succession.This is just a fancy term for the way rock layers are built up and changed by geologic processes.Which of these does a better job of describing my age? So, in both geology and paleontology, we want to be able to point to an object and say exactly how old it is.
In this method, scientists compare different layers of rock to determine an ordered sequence of events in geologic history.
He could be pretty confident that his super awesome dinosaur was about 175 million years old.
Stratigraphic and fossil succession are good tools for studying the relative dates of events in Earth's history, but they do not help with numerical dating.
Scientists piece together a story of how one event came before or after another.
Relative dating cannot tell us the actual age of a rock; it can only tell us whether one rock is older or younger than another.
