Water moving through soil and rocks is known as?

• A. Groundwater Flow
• B. Throughflow
• C. Percolation
• D. Overland Flow

Answer: (C)

Downward movement of water through soil and rock is called percolation. After water infiltrates the surface, it travels through the pore spaces and fractures in the soil and underlying rocks, typically moving downward under gravity and capillary forces. This process helps recharge groundwater as the infiltrated water reaches deeper, saturated zones. It differs from groundwater flow, which is the movement of water through saturated materials at depth; from throughflow, which is water moving through the soil layer itself, often downslope; and from overland flow, which is water that runs off the surface rather than seeping downward. So the vertical seepage through the soil and rocks aligns with percolation.
