Dew differs from precipitation in that dew

  • A.falls from a cloud like any other hydrometeor
  • B.occurs solely when the air is colder than freezing
  • C.consists of ice crystals rather than water
  • D.condenses directly onto a cooled surface

Answer: D

Radiative cooling of the surface below the dew point causes condensation in place. No cloud is involved and nothing falls, which is why it is not counted as precipitation. Its water still matters to surface energy and moisture budgets.
