Which of the following does NOT support the idea that the Moon formed from a large impact?

The idea that the Moon formed from a large impact, known as the Giant Impact Hypothesis, is supported by several lines of evidence. The presence of iron-poor rock in the Moon's composition suggests that it primarily originated from the Earth's outer layers, which would be more silicate-rich and less dense than the iron-rich core of the impactor or Earth itself. This supports the hypothesis as it aligns with the materials expected to come from such an impact.

The Moon's surface being heavily cratered is indicative of its age and exposure to impacts over billions of years. A heavily cratered surface is characteristic of a body that has not undergone significant geological activity since its formation, which is consistent with the aftermath of a large impact event that formed the Moon.

The existence of a large ring of debris supports the idea that material ejected during the impact eventually coalesced to form the Moon. Such a scenario would have generated a significant amount of debris orbiting the Earth, which eventually accreted to form the Moon.

In contrast, the Moon's high abundance of water does not support the impact hypothesis because it suggests processes that are more consistent with a later acquisition of water, rather than being a primary component formed from the planetesimals involved in the impact
