State whether the following is true or false.
Cloud droplets are lighter than the air around them, which is why clouds float.

  • A.True
  • B.False
  • C.True only at large scales
  • D.False only at small scales

Answer: B

Liquid water is very much denser than air and the droplets are falling continuously. They appear suspended because their fall speed is tiny and gentle updraughts are usually sufficient to offset it. A cloud is better pictured as droplets falling slowly through rising air.
