By using fossils and matching layers rock layers can be correlated to eachother.

true or false

The correct answer is True

Explanation:

In a geological technique called correlating rock layers, fossils are matched to specific rock layers and the relative age of rock layers is determined, by doing this scientist can compared the fossils and rock layers from other areas and thus determine the age of rock layers as usually a specific fossil does only belong to a specific geological era and then, if that fossil appears in a certain layer the rock layer would probably be as older as the fossil is. Thus, using fossils and matching them to layers, can determine to what geological period the rock layer belong and thus, these layers and fossils can be correlated to each other as they are linked by a specific period of time. This implies it is true, fossils and layers are used to determine how old a rock layer is and they are correlated.
