Question

Quizplus · Accepted Answer

Frost forms through a process called sublimation, where water vapour changes directly into ice without becoming a liquid first. This occurs when the ambient temperature is below the freezing point of water, and objects on the ground cool below the dew point temperature, causing the water vapour in the air to crystallize and form ice on surfaces.
