Question

Evaluate the age of rocks. You find 3 undisturbed rock layers. The middle layer is 120 years old. What can you say about the ages of the layers above and below it?

Answer 1

The lowest layers of rocks would be the oldest. The lower you go the older the layers of rocks go. As you go up the rocks get younger.

Answer 2

The layers above would be not as old and the layers below would be the older layers.
