Geologists use this type of method all the time to establish relative ages of rocks.Now, what if instead of being horizontal, this rock layer was found in a tilted position?Relative dating is an older method of placing events on the calendar of time.Artifacts from the earliest dates are in the lower levels or strata of Earth.Absolute dating is a method of determining the specific date of a paleontological or archaeological artifact or location based on a specific time scale or calendar.Scientists base absolute dating on measurable physical or chemical changes or on written records of events.Relative dating cannot establish absolute age, but it can establish whether one rock is older or younger than another.
