Correct Answer:
C. Percolation
Correct Answer: Percolation
Percolation is the process by which water moves downward through soil and porous rock layers under the influence of gravity. After rainfall or irrigation, water first infiltrates the soil surface and then continues to move deeper through spaces between soil particles. This process replenishes groundwater, supports plant roots, and helps maintain the water table. Percolation also naturally filters water by removing many impurities as it passes through different soil layers. The rate of percolation depends on factors such as soil texture, porosity, moisture content, and vegetation cover, making it an important concept in hydrology, agriculture, and environmental science.
