Passage

There is no atmosphere on the Moon, which means there can be no seas, rivers or water of any kind. We are accustomed to think of water as a liquid which does not boil away until it reaches a temperature of 212°, but if ever we picnic high up on a mountain, we find out our mistake. We soon discover that water boils more easily and at a lower temperature there than on the plains below. The reason is that there is less weight of air to keep the molecules of the liquid pressed down and so prevent them from flying off by evaporation. If there were no air pressure at all, the water would evaporate no matter how low its temperature and this is precisely what would happen on the Moon.
