Question

Water tightly held to soil particles is

• A. Bound water
• B. Capillary water
• C. Hygroscopic water
• D. Runaway water

Answer 1

The correct option is C Hygroscopic water

Bound water, is an extremely thin layer of water surrounding mineral surfaces.

Hygroscopic water is the water which is tightly attached to the colloidal particle of the soil. It is unavailable to the plants.

Capillary water is held in the soil against the pull of gravity. The water rises in the xylem due to the cohesion force between the water molecules.

Runaway water is the excessive water which exits or gets drained out from the soil after maximum absorption.

So, the correct answer is option C.
