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 cores remained largely intact, the remnants of these two bodies eventually reformed into Earth and moon. Which of the following statements could prove the theory that a planet-sized object struck a glancing blow on planet Earth?
a
Future scientists examine the isotopic concentrations of the cores of both Earth and the moon, and they find out they are equivalent.
b
Future scientists examine the isotopic concentrations of the cores of both Earth and the moon, and they find out they are not equivalent.
c
Scientist examine the isotopic concentrations on the surface of Earth and the moon, they find out they are nearly equivalent.
d
Scientist examine the isotopic concentrations on the surface of Earth and the moon, they find out they are not equivalent.
