Question

Which zone contains water that is under molecular attraction?

(a) Zone of rock fracture

(b) Zone of rock flowage

(c) Zone of saturation

(d) Zone of aeration

I had been asked this question by my school principal while I was bunking the class.

I'd like to ask this question from Factor Controlling Occurrence of Ground Water in division Ground Water for Irrigation through Wells and Tubewells of Irrigation Engineering

Answer 1

The correct answer is (d) Zone of aeration

For explanation I would say: Zone of aeration is the space above the water table and below the surface and the water exists in this zone by molecular attraction. The water in this zone is not at hydrostatic pressure and the gravity water moves through this zone.
