Sample Questions and Answers

Question 1. A farmer plants different crops in the same field each growing season instead of planting the same crop every year. Which agricultural practice is being used, and what is its primary environmental benefit?

A. Monoculture; increased soil erosion

B. Crop rotation; improved soil fertility and reduced pest populations

C. Clear-cutting; increased crop production

D. Urban agriculture; increased water pollution

Correct Answer: B. Crop rotation; improved soil fertility and reduced pest populations.

Explanation:
Crop rotation is the practice of growing different crops in the same field over successive seasons. This method improves soil fertility, reduces nutrient depletion, interrupts pest and disease cycles, and decreases the need for synthetic fertilizers and pesticides. For example, legumes can naturally replenish nitrogen in the soil through nitrogen fixation. Sustainable agricultural practices such as crop rotation are important for maintaining healthy ecosystems and are a major topic in AP Environmental Science Unit 5 and the AP Environmental Science exam.

Question 2. A community replaces traditional flood irrigation with drip irrigation for local farms. What is the primary environmental advantage of using drip irrigation?

A. Increased soil erosion

B. Improved water conservation by delivering water directly to plant roots

C. Greater fertilizer runoff into nearby rivers

D. Increased evaporation of irrigation water

Correct Answer: B. Improved water conservation by delivering water directly to plant roots.

Explanation:
Drip irrigation delivers water slowly and directly to the root zone of plants through a network of tubes or emitters. This method minimizes evaporation, reduces water waste, decreases runoff, and improves irrigation efficiency compared with flood irrigation. Water conservation is especially important in regions experiencing drought or limited freshwater supplies. Efficient irrigation practices are commonly discussed in AP Environmental Science Unit 5 as examples of sustainable resource management.

Question 3. A logging company harvests selected mature trees while leaving younger trees and most of the forest intact. Which forestry practice is being used?

A. Clear-cutting

B. Selective cutting

C. Strip mining

D. Slash-and-burn agriculture

Correct Answer: B. Selective cutting

Explanation:
Selective cutting involves harvesting individual mature trees while preserving much of the surrounding forest ecosystem. This practice helps maintain wildlife habitat, reduces soil erosion, protects biodiversity, and allows forests to regenerate naturally. Compared with clear-cutting, selective cutting generally has a lower environmental impact and supports more sustainable forest management. Forestry management practices and their environmental consequences are important topics covered in AP Environmental Science Unit 5.

Question 4. Overfishing has significantly reduced the population of a commercially valuable fish species. Which management strategy would best promote long-term sustainability of the fish population?

A. Remove all fishing regulations.

B. Establish catch limits and protect breeding habitats.

C. Increase fishing during spawning season.

D. Eliminate marine protected areas.

Correct Answer: B. Establish catch limits and protect breeding habitats.

Explanation:
Sustainable fisheries management aims to maintain healthy fish populations while allowing responsible harvesting. Catch limits help prevent overharvesting, while protecting spawning grounds and breeding habitats allows fish populations to reproduce and recover. Additional strategies such as seasonal closures and marine protected areas also contribute to long-term ecosystem health. Fisheries management and sustainable resource use are key concepts in AP Environmental Science Unit 5.

Question 5. A city converts a natural wetland into a commercial development. Which environmental consequence is most likely to occur?

A. Improved flood control and increased biodiversity

B. Reduced water filtration, increased flooding, and habitat loss

C. Increased groundwater recharge and cleaner surface water

D. Reduced stormwater runoff and improved ecosystem stability

Correct Answer: B. Reduced water filtration, increased flooding, and habitat loss.

Explanation:
Wetlands provide valuable ecosystem services, including filtering pollutants from water, absorbing excess stormwater, reducing flood risks, supporting biodiversity, and recharging groundwater. When wetlands are destroyed or developed, these natural benefits are lost, leading to greater flood potential, poorer water quality, and significant habitat destruction. Wetland conservation and land-use planning are major topics in AP Environmental Science Unit 5 and are frequently tested on classroom assessments and the AP Environmental Science exam.
