Answer:
Supersaturation
Explanation:
This term is used in earth science. Supersaturation happened in a natural atmosphere. It occurs when the relative humidity in the atmosphere is more than natural 100% with more vapor of water. It produces a saturation to the normal surface of the atmosphere with pure water and with pure ice.
So, when the atmosphere contains more vapors than that, it is theoretically possible. It is the result of supersaturation.
