What is the relative age of a rock?
The age determined by the things around it.
The age of an igneous rock.

A cave explorer found a bunch of Megalodon sharks teeth in a cave in the middle of the Arizona Desert. What best explains why he would discover shark fossils here?
Megalodons would hunt their prey on the surface as well the ocean
Megalodons were known to fly
Millions of years ago Arizona was under water. Over time the Earth changed, the ocean became a desert, and the shark's teeth were fossilized.
