How does replacing grass with cement and asphalt impact flooding after a heavy rain?
A. It promotes extra growth of vegetation, which prevents flooding.
B. It doesn't require watering or mowing and helps prevent flooding.
C. It allows rainwater to seep into the ground, which prevents flooding.
D. It prevents rainwater from seeping into the ground, causing water to stay on the surface.
Answer (2)
Replacing grass with cement and asphalt prevents rainwater from seeping into the ground, leading to excessive surface runoff and increased flooding risk. These hard surfaces create impervious areas that do not absorb water, overwhelming drainage systems during heavy rainfall. Consequently, this modification significantly raises the chance of localized flooding and water quality issues. ;
Replacing grass with cement and asphalt prevents rainwater from soaking into the ground, causing more water to stay on the surface. This leads to increased surface runoff, higher flood risk, and potential water quality issues. The correct answer is D: It prevents rainwater from seeping into the ground, causing water to stay on the surface.
