Question

Quizplus · Accepted Answer

Hoar frost forms when water vapor in the air comes into contact with cold surfaces and directly transitions into ice without becoming liquid first. This process, known as deposition, occurs under wet and cold conditions, leading to the growth of ice crystals that resemble feathers or needles on surfaces.
