The moon lacks life and varies dramatically in temperature. If we could keep a layer of water spread on the surface of the moon, what effect would it have?
A) Life would be possible but it would have to withstand these extremes in temperature.
B) Water would absorb and hold heat and moderate the temperature extremes.
C) The temperatures would drop to the lower extremes.
D) Because water has a high heat of vaporization, the temperatures would rise to the upper extremes.
E) Physical conditions would remain the same.

Water has a high heat capacity, which means it can absorb and retain a large amount of heat. If water were spread on the surface of the moon, it would moderate the extreme temperature changes, making it more hospitable for life to potentially exist.
