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.

The Earth has a big and a large iron core.The mantles of the Earth and the Moon have a similar set of  compositions. Computer simulations predict that the collision between Earth and a Mars is sized object would produce a Moon-sized satellite with a stable orbit.

Explanation:

As compared to the earth the moon does not have an iron core and the mantle of the earth and the moon have a similar set of compositions. The computer simulation is predicted that the collision between the earth and the mars and the moon-sized object satellite with a stable orbit. Theia impact of the proto-Earth and a Mars-sized planetesimal that took place about 4.5 billion years ago.

Is there a picture of the diagram?
