This diagram shows watershed in areas with various urbanization levels. When rain falls in areas with all natural ground cover, up to 85% will will infiltrate the ground, allowing only about 15% to run off the land. Runoff increases as urbanization increases, which can lead to flooding and water pollution. Which best explains why land development, or urbanization, leads to an increase in watershed during rainfalls and snow melt? Responses A Urbanized areas receive heavy rain because water evaporates quickly without the aid of absorbent plants.
