Question

Identify the correct match of type of water given in Column-I and its character in column-II and select the correct option.

Column-I		Column· II
(i)	Capillary water	(a)	Present in the form of hydrated oxides of Silicon and Aluminium
(ii)	Hygroscopic water	(b)	Goes down through large pores between soil particles and reach water table
(iii)	Combined water	(c)	Held in between small non-colloidal soil particles
(iv)	Gravitational water	(d)	Held tightly around soil particles by adhesive forces

Options

• (i) - (c), (ii) - (d), (iii) - (a), (iv) - (b)

• (i) - (c), (ii) - (b), (iii) - (d), (iv) - (a)

• (i) - (c), (ii) - (d), (iii) - (b), (iv) - (a)

• (i) - (c), (ii) - (a), (iii) - (b), (iv) - (d)

Answer 1

(i) - (c), (ii) - (d), (iii) - (a), (iv) - (b)

Explanation:

Capillary water is available for plant growth because it is retained between soil particles. Plants are unable to absorb hygroscopic water that is strongly bonded to soil particles. The combined water is mixed with minerals in the soil that are not required by the plants. Gravitational water falls to the ground and joins the water table, making it unavailable to plants for absorption.
