Why does evaporation remain low in icy regions because of low temperature?

Correct answer: Because water molecules get less energy to become vapour

Direct answer: A is correct. Evaporation occurs when some molecules at a liquid or ice surface gain enough energy to escape into the air. Low temperature means that the average kinetic energy of the molecules is lower, so fewer surface molecules have the energy needed to leave. Ice can also change directly into water vapour by sublimation, but low temperature generally makes this process slow as well. Evaporation is not determined only by whether water is present; temperature, exposed surface, wind, and the dryness of the air also matter. A is correct because it identifies the energy limitation. B is wrong because ice is solid water. C is wrong because air remains present in cold regions. D is wrong because icy regions can receive sunlight, even though the amount or seasonal duration may vary. Memory cue: colder molecules have less energy to escape, so phase change to vapour slows.
