Question

which factor affects the amount of runoff that occurs in an area?
○ land use
○ the water table
○ the saturation zone
○ amount of nutrients in soil

Explanation:

To determine which factor affects runoff:

• Land use (e.g., paved surfaces vs. forests) directly impacts how much water runs off (paved areas have more runoff).
• The water table is the underground water level, not a direct runoff driver.
• The saturation zone refers to fully wet soil layers, not a primary runoff - influencing factor.
• Soil nutrients do not relate to runoff volume.

Answer:

A. land use
