Relitive dating

Sediments are usually laid down in horizontal beds.

Any observable tilting or swirling is due to disruption of the process. Material that intrudes or cuts into a horizontal bed is assumed to be younger than the material that is disrupted.

ANSWER: Relative dating is used to determine the relative ages of geologic strata, artifacts, historical events, etc.One known example where this assumption was used is very misleading.Ice cores showed the age of a military plane buried in the artic as thousands of years old.Consider a lake that dries out or somehow contains older sediments that are washed into it.These sediments are deposited on top of younger sediments currently being deposited in the lake.
