The correct answer is:

✅ Ice crystal growth

Why?

Snowflakes form through a process called crystallization:

Water vapor in clouds freezes directly into tiny ice crystals (skipping the liquid phase).

These crystals grow as more vapor condenses onto them, forming hexagonal shapes.

Branching patterns emerge due to temperature/humidity changes as flakes fall.

Key Factors:

Temperature: Determines crystal shape (e.g., plates, needles, dendrites).

Humidity: More moisture = more intricate flakes.

Why Not the Others?

❌ Condensation: Forms water droplets (rain), not ice.

❌ Frozen raindrops: Creates sleet, not snowflakes.

Fun Fact: No two snowflakes are exactly alike due to unique growth paths! ❄️🔍

Bonus: The largest snowflake recorded was 15 inches wide (1887, Montana). 🌨️📏
