a) Gravitational water
b) Capillary water
c) Hygroscopic water
d) Chemically bound water
​

Answer 1

Answer:

Answer 2

The type of water stored is Chemically bound water

• Combined water is water that has been chemically combined in the complex structure of soil minerals.

• The sole water that remains after the water has been removed from the soil by heating it is in the hydrated oxides of aluminum, iron, silicon, and other metals.

• It is inaccessible to plants and can only be extracted from the soil by applying intense heat, but only after constant changes in the material and chemical composition of the soil have occurred.
