Natural abundances vary based on the planet and its formation history. For example, Mars and Earth have different oxygen isotope ratios. It has been suggested that the moon was formed when a planet-sized object

eventually reformed into Earth and moon. Explain how you could use isotopic analysis to support this theory.
