Which of the following would be considered an advantage of increased urban sprawl? A As individuals move out of urban areas to nearby suburbs, the population densities of cities will decrease, reducing the spread of infectious disease. B As new homes are built in suburban areas, the cost of materials will decrease, reducing the need to clear-cut old-growth forests.

A group of students want to increase the amount of water infiltration around the property of their urban high school by replacing all the existing impermeable walkway pavers with permeable ones. The school board will not move forward with any property changes unless the students conduct an experiment and collect evidence to help prove that their proposed suggestion to increase water infiltration will be effective. The students create two identical pallets using soil taken from the school's property and install impermeable pavers similar to those found on the school's property in one of the pallets. They install permeable pavers in the other pallet. The students pour exactly the same amount of water over both sets of pavers, leave both pallets in exactly the same environmental conditions, and after one hour measure the amount of water that infiltrated the soil. Which of the following identifies and describes the equipment needed to best determine the amount of water that infiltrated the soil? A) A scale should be used to measure the mass of both pallets immediately after pouring the water over the pavers and immediately after the one-hour wait time. B) A ruler should be used to measure the level of water above the pavers in both pallets immediately after pouring the water over the pavers and immediately after the one-hour wait time. C) A soil triangle should be used to determine the soil texture in both pallets before and after the water is added to both pallets. D) A turbidity meter should be used to determine the amount of particulate matter in both pallets before and after the water is added to both pallets.

An environmental agency wants to evaluate the effectiveness of rain gardens in reducing the impact of urban runoff from an impervious parking lot and from the roof of the building. The parking lot is slightly sloped so the rainwater flows toward the gardens. The runoff from the roof is collected by various downspouts and directed toward the gardens. Scientists at the agency plan to monitor the effectiveness by measuring the water quality of the storm water as it moves through the gardens during and after storm events. Which of the following would be the best control in this experimental design? A Water samples collected from a faucet inside the building B Water samples collected from the roof or parking lot before they passed through the gardens C Soil samples collected from different rain gardens on the property D Soil samples collected from under the parking lots around the city
B
An urban planner is designing a new urban housing development in a currently rural area near an existing city. The urban development will have five 10-story apartment buildings, two basketball courts, a playground with permeable foam pavers, a 10-acre green space with a small man-made pond, one 5-story parking deck, and direct access to the mass transit train line. Which of the following aspects in the design for this new urban development would most likely have the greatest negative environmental impact? A The two basketball courts B The five apartment buildings C The 10-acre green space D The playground
B
Which of the following is an example of an environmental benefit of aquaculture? A Raising large numbers of fish in a small area near the shore will increase the profitability of the fish harvest. B Raising fish using aquaculture and feeding human populations with the harvest reduces the number of fish caught from the ocean. C Aquaculture supports the food supply for humans, and the fish can also be released into the wild to repopulate the ocean. D Aquaculture results in large amounts of fish that can feed large numbers of people and help to increase human population growth.
