Quizplus · Accepted Answer

Freezing rain (ice storm) or sleet occurs when there is a warm layer of air between the cloud and the cold surface. This warm layer causes the precipitation (usually in the form of rain) to melt as it falls. However, when the melted precipitation reaches the cold surface, it freezes on contact, causing an icy glaze to form.
