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 struck a glancing blow on Earth although The Corrs remained largely intact the remittance of these two bodies eventually reform into Earth and Moon explain how you could use isotopic analysis to support this Theory
