Explain groundwater recharge as you would to a capable student, in 3-4 sentences.

Groundwater recharge is the process by which water from precipitation (rain or snow) moves downward through soil and rock layers to refill underground aquifers—essentially nature's way of restocking our underground water reserves. When rain falls, some water runs off into streams, some evaporates, and some soaks into the ground; the portion that continues percolating deep enough becomes groundwater. This process is crucial because it replenishes the water we extract from wells and maintains the base flow of streams and rivers. Recharge rates vary depending on factors like soil type, land cover, and how much rain falls—sandy soils allow faster infiltration than clay, while paved surfaces prevent it almost entirely.
