What's the difference between rime and snow song?

I know the difference between rime and snow song.

1. Formation temperature: rime refers to milky ice crystal deposits that directly condense and freeze on objects at low temperature. Snowflakes are ice crystals formed in cold weather, covering branches and leaves.

2. Formation conditions: The conditions for the formation of rime are harsh, requiring low temperature and sufficient water vapor, so rime is not common. Snowflakes usually form in cold winter and only appear in very cold areas.

3. Appearance and density: rime is usually milky white with low density, while rime is white crystal with relatively high density.
