Which of these boxes should be marked as true?

On an even smaller scale-such as a single urban city in a river basin-you can see how human activity has affected the water cycle. The illustration on the left is an example of how water flows when there is urban development in a river basin; the ilustration on the right is an example of how water flows in an intact forested area of a river basin. Compare the two diagrams carefully before answering the following question. 25% Transpiration 40% Transpiration 6096 Runoff 10% Runoff 10% shallow infiltration 20% shallow infiltration 590 Deep infiltration 30% Deep infiltration Urban development generally disrupts the natural flow of water in a river basin. Given the information in the illustrations, which of the following are true Check all that apply. Unsaturated forested ground cover will likely cause runoff to increase by 50 percentage points compared with impermeable surfaces such as concrete on city sidewalks. The higher abundance of vegetation in intact forested areas will increase uptake of water from the soil. This will result in less water in the shallow soil layers compared with developed urban areas. Groundwater used to fill underground aquifers will decrease by 25 percentage points in developed urban areas compared with natural forested areas.

Explanation / Answer

True because the groundwater used to fill underground aquifers will decrease by 25 percentage points in developed urban areas compared with natural forest areas.
