Inclusions Inclusions- are pieces of one rock unit that are within another rock unit. The rock containing the inclusions has to be older than the rock that gave the inclusion. Radioactive materials emit particles at a constant rate.The top layer of exposed strata would be the youngest (since it was the last to form).” Exceptions to the Law of Superposition Much of the rock strata observed on Earth’s surface has been impacted by the crustal dynamics of the Earth.“How can a scientist determine the relative age of rock layers under these conditions? Put these people in order from youngest to oldest..
