How Rainwater Recharges Groundwater: Soil Layer Diagram #125971 (License: Personal Use)

This educational diagram depicts a vertical cross-section of the Earth’s subsurface during rainfall, illustrating infiltration processes. The top layer shows organic-rich topsoil with plant roots, followed by a zone of unsaturated soil, then a saturated aquifer layer, and finally impermeable bedrock below. Blue lines represent raindrops; orange dots indicate dissolved minerals or contaminants moving downward with the water.

Used in environmental science, hydrology, and sustainability education to explain groundwater recharge, contamination pathways, and watershed management. Targets students, educators, and policymakers seeking foundational knowledge of the water cycle and aquifer protection.
