Answer Key

1. Explain the difference between snowflakes and snow crystals. A snow crystal is a single crystal of ice. A snowflake is a general term for an individual snow crystal, a few snow crystals stuck together, or large agglomerations of snow crystals that form “puff-balls.”

2. How do snow crystals form? Snow crystals form when water vapor condenses directly into ice.

3. What two factors determine the shape of a snow crystal? Temperature and humidity.

4. Look at the Morphology Diagram. What conditions encourage complex shapes to form?
Higher humidity and temperatures between -10° to -20° C (5° to 15° F).

5. Explain the term “supercooled.” Supercooled means that the water is cooled below the freezing point.
