Question

Quizplus · Accepted Answer

The most widely accepted theory for the presence of water ice on the Moon suggests that it was brought to the surface by the impacts of meteoroids and comets. These impacting bodies contain water and other volatile compounds that can be released upon impact, and some of this water could have been deposited on the Moon's poles where it is permanently shadowed and cold enough to keep the water from evaporating. The most likely source of lunar ice is the impacts of meteoroids and comets, which would often contain water molecules that could be deposited on the Moon's surface. There is not enough evidence to suggest that water was present on the Moon when it formed, and there is no evidence of recent volcanism on the Moon. Contamination from human exploration is also not a likely source, as the ice has been observed in areas where humans have never landed.
