prize1-6, Exercise 3: Snow, rain and glaze ice

Model answer:

In the British Isles the air is often only a degree or two from the point where snow melts on the way down, so a slight rise in temperature turns snow into sleet or rain, and a slight fall does the reverse. Freezing rain falls as liquid and freezes on contact with cold surfaces, coating roads, wires and trees in clear glaze ice that is hard to see and very slippery, so it is often more dangerous than snow.
