What term refers to water that enters an aquifer and refills a groundwater store?

• A. Store
• B. Recharge
• C. Source
• D. Rainwater harvesting

Answer: (B)

Groundwater recharge is the process by which water enters an aquifer and replenishes the groundwater store. When precipitation or meltwater infiltrates the soil, some of it percolates down through the unsaturated zone until it reaches the saturated zone, adding to the volume of groundwater. This recharge balances withdrawals and is essential for keeping aquifers stocked. It can occur naturally from rainfall, river or lake seepage, or be enhanced by human actions like artificial recharge basins. The other terms don’t fit because a store is the groundwater body itself, a source is where the water comes from, and rainwater harvesting is a method of collecting rainwater for use, not the act of refilling an aquifer.
