Q. A thin film of water covering the soil particles and held strongly by attractive forces is called :

(a) Runaway

(b) Hygroscopic 

(c) Gravitational

(d) Capillarity

Solution :

Correct option : B The thin film of water covering the soil and held by attractive forces is known as Hygroscopic water. Runaway water is the excess water that flows on the surface of the soil. It takes the top layer of soil along with it Groundwater is the water that is stored deep inside the soil seeping through many layers. Capillary water is the water that can rise in a thin tube due to capillary action. So the correct answer is ‘Hygroscopic water’.
