To be effective, a scientific theory must be continually tested. If observations and experiments favor it, a theory can be further developed and refined. If they do not, the theory must be reformulated or rejected. Comparing what you know about the predictions of each Moon formation theory, determine which of the following observations and experiments have been verified.
A- Earth has a large iron core, but the Moon does not.
B- The mantles of Earth and the Moon have similar compositions.
C- Computer simulations predict that a collision between
D- Earth and a Mars-sized object would produce a Moon-sized satellite with a stable orbit.
