What is the difference between infiltration and runoff? Explain using CER.
Infiltration is the process where water soaks into the ground, while runoff is the water that flows over the land surface toward streams or lakes. After a rainstorm, observations show that water puddles less and the soil becomes wetter in grassy, uncovered areas, but on a nearby paved parking lot the water quickly moves downhill into a storm drain. For example, a rain of 1 inch on a permeable lawn left the top 2–3 inches of soil visibly damp and no standing water after 30 minutes, while the same rain on the pavement created flowing water that reached the gutter within minutes. The soil in the grassy area has pore spaces between particles and plant roots that let water enter and be held in the ground; this explains why the lawn’s soil became wetter and puddles did not form—water infiltrated. In contrast, pavement is impermeable, so water cannot enter the ground there; instead gravity causes that water to move across the surface as runoff toward lower areas like the storm drain. Because infiltration reduces the amount of water available to flow over the surface, areas that allow more infiltration typically have less runoff. Human surfaces (like parking lots) and saturated soils reduce infiltration and increase runoff, which can cause faster movement of water and greater risk of flooding.
