Seriation uses the assumption that once a tool was developed, its use would become more widespread.Stratigraphy uses the assumption that higher layers or strata were laid down after lower layers.With out individual time stamps the process of dating these structures could become extremely difficult.

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

This technique does not give specific ages to items.

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.

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.

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.

Ice core sampling normally uses the assumption that the ring bands observed represents years.

One known example where this assumption was used is very misleading.

With this in mind geologist have long known that the deeper a sedimentary rock layer is the older it is, but how old?
