Relative dating ice cores

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 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.
