Problem: The most popular theory of how the Moon formed states that a large object struck the Earth and sent a large amount of the Earth's crust into space. This material eventually cooled and formed the Moon. This event probably occurred early in the Earth's formation. Evidence to support this theory comes from rock samples recovered from the Moon. They reveal that the Moon is mainly composed of silicate minerals and is deficient in iron. The lack of iron on the Moon, as compared with Earth, suggests that it was formed from the outer crust of the Earth, which contains much less iron than its core. End of reading passage.
