Which of the following statements depend on the absolute dating of events? Dinosaurs went extinct before monkeys evolved. Birds separated from dinosaur relatives 120 million years ago. The oldest Earth rocks are 3.9 billion years old. In undisturbed rock layers, we find older rock layers beneath younger rock layers.

The correct answer of the given question above would be the third option. The statement that depends on the absolute dating of events is this: The oldest Earth rocks are 3.9 billion years old. Absolute dating is the method of determining the specific date of an archaeological or paleontological artifact. In contrast, relative dating is just the determining of the relative order of events and not necessarily the estimated age of the artifact.
