Arrange these steps of the hydrological cycle in order beginning with evaporation.
1. growth into precipitation sized particles
2. evaporation from the surface
3. runoff and return to the ocean
4. condensation into cloud droplets

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

Answer: C

Correct answer: 2 - 4 - 1 - 3

Beginning with evaporation the order is forced. Water leaves the surface as vapour, condenses onto nuclei to form cloud droplets, grows by coalescence or through the ice phase into particles large enough to fall, and finally runs off and returns to the ocean. Each step needs the product of the one before it, so no other ordering is possible.
