Water soaking into the ground is described by which term?

• A. Percolation
• B. Infiltration
• C. Runoff
• D. Riparian Zone

Answer: (B)

Water soaking into the ground is infiltration—the process of water entering the soil from the surface and moving into the soil’s pore spaces. Percolation is the deeper downward movement of that infiltrated water through the soil toward groundwater, which happens after infiltration. Runoff is water that flows over the surface instead of soaking in, and a riparian zone is the vegetated area along a stream, not a movement process. Infiltration is the best term because it directly describes water entering the soil from the surface.
