The statement that is NOT true of relative dating is:

D Relative dating depends on the use of radioactive isotopes to give exact ages of layers.

Relative dating does not provide exact ages; rather, it establishes a sequence of events and compares the ages of rock layers and fossils based on their relationships to each other. The use of radioactive isotopes is part of absolute dating, which provides more precise age estimates.
