As impervious surfaces increase and deforestation increases, __________.
both runoff and infiltration increase flooding frequency increases infiltration increases runoff decreases
As impervious surfaces increase and deforestation increases, flooding frequency increases.
This is because impervious surfaces, such as roads and buildings, prevent water from being absorbed into the ground, leading to increased runoff. Deforestation also reduces the amount of vegetation that can absorb water, further contributing to higher runoff and increased flooding.
