The dark areas on the moon’s surface are called ?maria?, Latin for “seas,” and were once thought to be bodies of water. In fact, the maria are not “seas” at all, but plains of solidified lava. Given that there is no atmosphere on the moon, how can you explain the absence of liquid water on the moon’s surface?
Solution to 31DQ Moon has no atmosphere, surface of the moon is exposed to vacuum and outer space. The gravitational force of moon is also very less compared to earth. Thus the water molecules even if present in moon surface will be ionized and will escape to the outer space. Therefore, moon surface doesn't have water.
