Researchers can first apply an absolute dating method to the layer.

Layers of rock build one atop another — find a fossil or artifact in one layer, and you can reasonably assume it’s older than anything above it.Paleomagnetism is often used as a rough check of results from another dating method.Tephrochronology: Within hours or days of a volcanic eruption, tephra — fragments of rock and other material hurled into the atmosphere by the event — is deposited in a single layer with a unique geochemical fingerprint. Relative dating has a lot of variables, such as the desire to date others or the uncertainty regarding whether or not the person can develop into a partner. You’re dating one person and have one goal in mind (to be in a relationship with this person).Relative dating and radiometric dating are used to determine age of fossils and geologic features, but with different methods.
