In which condition can relative humidity approach 100 percent without rainfall?

Answer and explanation

Correct answer: When air is saturated but droplets do not grow to raindrop size

Correct answer: A. Relative humidity compares the actual water vapour in air with the maximum vapour the air can hold at the same temperature. A value near 100 percent means the air is nearly saturated. However, saturation alone does not guarantee rainfall. Tiny cloud droplets must collide, combine or otherwise grow large and heavy enough to overcome upward air currents and fall to the ground. If the droplets remain very small, they can stay suspended as cloud or mist even while humidity is near 100 percent. A is correct because it separates saturation from precipitation. B is wrong because air without water vapour cannot have high relative humidity. C is wrong because an infinite temperature is not a realistic atmospheric condition and would not explain saturation. D is wrong because the end of the atmosphere is unrelated. Memory cue: 100 percent humidity means saturation, not necessarily rain.
