If temperature changes sharply in the lower air, what difficulty can occur when identifying the type of precipitation?

Correct answer: Rain, snow, and frozen forms may change or mix while falling

Correct answer: A. The form of precipitation at the cloud base is not always the form observed at the ground. A snowflake may pass through a warm layer and melt into rain. Rain may then enter a shallow sub-freezing layer and freeze partly, producing ice pellets or freezing rain, depending on the temperature profile and the depth of each layer. Rapid or alternating temperature changes therefore make it difficult to classify the final precipitation from the cloud alone. A is correct because rain, snow, sleet, and freezing forms can transform or occur together. B is wrong because precipitation remains water in liquid or solid form; it does not become waterless. C is wrong because a changing lower temperature does not automatically remove clouds. D is physically impossible in this context. Memory cue: to identify precipitation, trace the particle through every warm and cold layer between cloud and ground.
