Discussion
Consider the following statements about ice accretion.
1. Glaze is dense and clear because the water freezes slowly.
2. Rime is opaque because air is trapped as droplets freeze fast.
3. Rime is denser and more damaging than glaze.
Answer: D
Correct answer: 1 and 2 only
Statements 1 and 2 are correct: slow freezing lets air escape and gives glaze its clear, dense structure, while the rapid freezing of individual droplets traps air and makes rime opaque and light. Statement 3 reverses the comparison - glaze is the denser and by far the more damaging of the two, precisely because it is solid ice rather than an aerated deposit.
