Which process describes water moving through rocks in the ground?

• A. Groundwater storage
• B. Groundwater flow
• C. Percolation
• D. Interception

Answer: (B)

The main idea is how water moves beneath the surface within rocks—the groundwater system. Groundwater flow describes this movement of water through saturated rock and sediments in aquifers, driven by hydraulic gradients. It can travel through pore spaces and fractures and may move slowly over long distances, supplying springs and wells. This is different from percolation, which is water seeping downward through soil toward the water table after rainfall, not movement through rocks in the underground aquifer. Storage refers to how much water is held in the groundwater system, not its movement. Interception is just rainfall caught by vegetation and does not involve groundwater. So the water moving through rocks underground is groundwater flow.
