What are some examples or non examples of relative age?

Relative age refers to the age of an object or event in relation to another. For example, if a rock layer is found above another layer, the upper layer is younger relative to the lower one. Non-examples include absolute age, which provides a specific age in years, such as "this rock is 100 million years old," or events that are not compared, like stating that a certain dinosaur lived during the Mesozoic era without reference to another species.
