Arrange these drop categories in order of increasing size.
1. small raindrop
2. cloud droplet
3. large raindrop
4. drizzle drop

  • A.2 - 4 - 1 - 3
  • B.3 - 1 - 4 - 2
  • C.4 - 2 - 1 - 3
  • D.2 - 1 - 4 - 3

Answer: A

The boundaries are conventional but the ordering reflects a real progression in fall speed and in growth mechanism. Drizzle is conventionally taken to begin near a hundred micrometres in diameter. Terminal velocity rises steeply across that boundary.
