Environmental Science Practice Test

Correct answer: C

The correct answer is Its natural replenishment rate can keep pace with use when the system is managed responsibly.

1. Identify the environmental system: Determine whether the prompt concerns ecosystems, resources, pollution, climate, human impacts, policy, or environmental data.
2. Connect the evidence: Renewability depends on replenishment, use rate, management, and the condition of the resource system.
3. Check the tradeoff or relationship: Compare the answer with the stated data, system boundary, cause, effect, or solution constraint before choosing.

Correct answer: D

The correct answer is Water use connects surface water, groundwater, precipitation, ecosystems, agriculture, and communities.

1. Identify the environmental system: Determine whether the prompt concerns ecosystems, resources, pollution, climate, human impacts, policy, or environmental data.
2. Connect the evidence: Water moves among reservoirs and users, so a decision in one part can affect other parts of the system.
3. Check the tradeoff or relationship: Compare the answer with the stated data, system boundary, cause, effect, or solution constraint before choosing.

Correct answer: A

The correct answer is It can cause waterlogging, salinization, runoff, or groundwater depletion depending on conditions.

1. Identify the environmental system: Determine whether the prompt concerns ecosystems, resources, pollution, climate, human impacts, policy, or environmental data.
2. Connect the evidence: Irrigation changes water balance and can concentrate salts or increase withdrawals when drainage and recharge are limited.
3. Check the tradeoff or relationship: Compare the answer with the stated data, system boundary, cause, effect, or solution constraint before choosing.

Correct answer: B

The correct answer is A fish population can fall faster than it reproduces, reducing future harvests and food-web stability.

1. Identify the environmental system: Determine whether the prompt concerns ecosystems, resources, pollution, climate, human impacts, policy, or environmental data.
2. Connect the evidence: Harvest above a population’s replacement rate can reduce stock size and alter ecosystem relationships.
3. Check the tradeoff or relationship: Compare the answer with the stated data, system boundary, cause, effect, or solution constraint before choosing.

Correct answer: C

The correct answer is Environmental impacts associated with stages of a product or service from materials to use and disposal.

1. Identify the environmental system: Determine whether the prompt concerns ecosystems, resources, pollution, climate, human impacts, policy, or environmental data.
2. Connect the evidence: Life-cycle thinking considers extraction, production, transport, use, reuse, recycling, and disposal when relevant.
3. Check the tradeoff or relationship: Compare the answer with the stated data, system boundary, cause, effect, or solution constraint before choosing.

Correct answer: D

The correct answer is A cost or benefit of an activity that affects people or systems not fully represented in the market decision.

1. Identify the environmental system: Determine whether the prompt concerns ecosystems, resources, pollution, climate, human impacts, policy, or environmental data.
2. Connect the evidence: Pollution can impose costs on communities or ecosystems even when those costs are not included in a product price.
3. Check the tradeoff or relationship: Compare the answer with the stated data, system boundary, cause, effect, or solution constraint before choosing.

Correct answer: A

The correct answer is They can reduce resource use and impacts while maintaining needed services.

1. Identify the environmental system: Determine whether the prompt concerns ecosystems, resources, pollution, climate, human impacts, policy, or environmental data.
2. Connect the evidence: Using less energy, water, land, or material for a comparable outcome can reduce pressure on Earth systems.
3. Check the tradeoff or relationship: Compare the answer with the stated data, system boundary, cause, effect, or solution constraint before choosing.

Correct answer: B

The correct answer is A shared resource may be overused when individuals gain from use while costs are distributed across the community.

1. Identify the environmental system: Determine whether the prompt concerns ecosystems, resources, pollution, climate, human impacts, policy, or environmental data.
2. Connect the evidence: Shared-access resources need rules, monitoring, cooperation, or incentives to avoid depletion.
3. Check the tradeoff or relationship: Compare the answer with the stated data, system boundary, cause, effect, or solution constraint before choosing.

Correct answer: C

The correct answer is Maintaining ground cover, contour practices, or other methods that slow runoff and keep soil in place.

1. Identify the environmental system: Determine whether the prompt concerns ecosystems, resources, pollution, climate, human impacts, policy, or environmental data.
2. Connect the evidence: Vegetation and land-management practices can reduce wind and water erosion and protect soil structure.
3. Check the tradeoff or relationship: Compare the answer with the stated data, system boundary, cause, effect, or solution constraint before choosing.

Correct answer: D

The correct answer is A solution can have environmental, economic, social, safety, and long-term effects that must be compared.

1. Identify the environmental system: Determine whether the prompt concerns ecosystems, resources, pollution, climate, human impacts, policy, or environmental data.
2. Connect the evidence: Evaluating alternatives requires criteria, constraints, evidence, and attention to unintended consequences.
3. Check the tradeoff or relationship: Compare the answer with the stated data, system boundary, cause, effect, or solution constraint before choosing.
