What process brings water into the ground?

• A. Runoff
• B. Evaporation
• C. Condensation
• D. Infiltration

Answer: (D)

Water entering groundwater happens through infiltration—the downward movement of surface water into the soil, through pore spaces, and toward the aquifer. This is how rainfall or melted snow soaks in and replenishes groundwater. Runoff moves water across the surface and into streams or rivers without soaking in, so it doesn’t directly recharge groundwater. Evaporation turns liquid water into vapor and leaves the surface, while condensation forms liquid water in the air or on surfaces but doesn’t push water into the ground. Infiltration depends on soil properties and moisture—well-drained soils absorb quickly, whereas compact or clay-rich soils slow it and limit groundwater recharge.
