Relative dating is the science of determining the relative order of past events (i.e., the age of an object in comparison to another), without necessarily determining their absolute age, (i.e. In geology, rock or superficial deposits, fossils and lithologies can be used to correlate one stratigraphic column with another.Prior to the discovery of radiometric dating in the early 20th century, which provided a means of absolute dating, archaeologists and geologists used relative dating to determine ages of materials.Cross-cutting relationships is a principle of geology that states that the geologic feature which cuts another is the younger of the two features. It was first developed by Danish geological pioneer Nicholas Steno in Dissertationis prodromus (1669) and later formulated by James Hutton in Theory of the Earth (1795) and embellished upon by Charles Lyell in Principles of Geology (1830).

Now, because we've already established that this cake is pure insanity, you're going to cut out a big hole in the middle that pierces all 3 layers and stick in some new feature. This exact same concept can be applied to layers of rock underneath the surface.

We know that we can relatively date layers of rock by knowing that the layers on bottom are older than the layers on top.
