Discussion
Consider the following statements about secondary ice production.
1. It can raise crystal concentrations far above the nuclei available.
2. Rime splintering is the best established of the proposed mechanisms.
3. It requires no pre-existing ice in the cloud at all.
Answer: B
The first two are correct and describe the process. The third is wrong by definition, since secondary production multiplies existing ice rather than creating the first crystal from nothing. A primary nucleation event is always required to start the chain.
