We don't need to know what year any of these movies came out to place them in order of relative age.
Nemo is the oldest, followed by Twilight, Hunger Games, and the Avengers Again, we have not stated anything about the actual age of these movies, we've just put them in order relative to one another.
Long before geologists tried to quantify the age of the Earth they developed techniques to determine which geologic events preceded another, what are termed "relative age” relationships.
These techniques were first articulated by Nicolas Steno, a Dane living in the Medici court of Italy in the 17th C.
This technique does not give specific ages to items.
It only sequences the age of things or determines if something is older or younger than other things.
Some types of relative dating techniques include climate chronology, dendrochronology, ice core sampling, stratigraphy, and seriation.
We'll explore both relative and numerical dating on our quest to understand the process of geological dating.
Along the way, we'll learn how stratigraphic succession and radioactive decay contribute to the work of paleontologists.
