Put these zones in order from the ground surface downward.

1. Zone of saturation   2. Capillary fringe   3. Soil water belt   4. Intermediate belt

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

Answer: D

Correct answer: 3, 4, 2, 1

From the surface downward: the soil water belt, where roots and evaporation dominate; the intermediate belt, through which water percolates; the capillary fringe, held above the water table by surface tension; and then the zone of saturation. The first three together make up the zone of aeration, and the water table is the boundary between the fringe and the saturated zone.
