Which of the following is not a category of soil water?

  • A.Hydroscopic water
  • B.Hydrosphere water
  • C.Capillary water
  • D.Gravitational water

Answer: B

The one that is not a category of soil water is Hydrosphere water.

Soil water is classified physically as hygroscopic water (held as a thin film on soil particles at very high tension and unavailable to plants), capillary water (held in the small pores against gravity and largely available to plants) and gravitational water (free water in the large pores that drains away under gravity).

The hydrosphere is the whole body of water on Earth, oceans, rivers, lakes, ice and groundwater, not a form of water held in the soil. ('Hydroscopic' in option A is the paper's spelling of hygroscopic.)
