Which term describes water that saturates the soil and fills all available pore spaces?

Which term describes water that saturates the soil and fills all available pore spaces?

• A. Saturated
• B. Discharge
• C. Porosity
• D. Percolines

Answer: (A)

Saturation describes the state where every pore space in the soil is filled with water. When the amount of water is enough to push out all the air from those voids, the soil becomes saturated, and the pore network is completely water-filled. This is different from porosity, which is simply how much empty space the soil has, not how much of that space is water-filled. Discharge refers to water leaving a system, not the fill state of the pores. Percolines isn’t a standard term for this context; the related process is percolation, which describes movement of water through soil, not the state of full pore occupancy. So the term describing water that saturates the soil and fills all available pore spaces is saturation.
