10. Review and Edit: Before submitting your FRQ, take a few minutes to review your response for errors and omissions. Make sure you have answered all parts of the question completely and that your arguments are well-supported.

Example FRQ and Breakdown

Let's consider a hypothetical FRQ based on Unit 6:

FRQ:

A community is considering building a new power plant to meet its growing energy demands. They are considering two options: a coal-fired power plant and a solar power plant.

(a) Describe two environmental impacts associated with the extraction and use of coal. (2 points)

(b) Describe two environmental impacts associated with the construction and operation of a solar power plant. (2 points)

(c) Explain one economic benefit and one economic drawback of using solar energy compared to coal. (2 points)

(d) Propose one government policy that could encourage the development of solar energy and explain how it would achieve this goal. (2 points)

Breakdown of Expected Answers:

(a) Coal Environmental Impacts:

• Mining Impacts:
  • Habitat Destruction: Mountaintop removal mining or underground mining can destroy forests, wetlands, and other habitats. This leads to loss of biodiversity and disruption of ecosystem services.
  • Water Pollution: Acid mine drainage occurs when rainwater flows through coal mines, picking up sulfuric acid and heavy metals. This contaminates streams and rivers, harming aquatic life.
• Combustion Impacts:
  • Air Pollution: Burning coal releases pollutants such as sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter (PM). These pollutants contribute to acid rain, smog, and respiratory problems.
  • Greenhouse Gas Emissions: Coal combustion releases large amounts of carbon dioxide (CO2), a major greenhouse gas that contributes to climate change.

(b) Solar Environmental Impacts:

• Manufacturing Impacts:
  • Resource Depletion: The production of solar panels requires materials such as silicon, cadmium, and tellurium, which are finite resources. Mining and processing these materials can have environmental consequences.
  • Hazardous Waste: The manufacturing process can generate hazardous waste products that need to be disposed of properly to prevent pollution.
• Land Use Impacts:
  • Habitat Loss: Large-scale solar farms can require significant amounts of land, which may lead to habitat loss and fragmentation.
  • Visual Impact: Some people find solar farms to be unsightly and detract from the natural beauty of the landscape.

(c) Economic Benefits and Drawbacks of Solar:

• Economic Benefit:
  • Reduced Fuel Costs: Solar energy does not require fuel, so operating costs are lower compared to coal-fired power plants. This can lead to long-term savings for consumers and businesses.
• Economic Drawback:
  • High Initial Investment: Solar power plants require a significant upfront investment in equipment and installation. This can be a barrier to entry for some communities or businesses.

(d) Government Policy to Encourage Solar:

• Policy Example:
  • Tax Credits: The government could offer tax credits to homeowners and businesses that install solar panels.
• Explanation:
  • Tax credits reduce the initial cost of solar energy, making it more affordable and attractive to consumers. This incentivizes the adoption of solar energy and helps to drive down prices over time.

Key Takeaways from the Example:

• Each part of the question requires a specific type of response (describe, explain, propose).
• The answers must be specific and relevant to the context of the question.
• Environmental science terminology is used throughout the response.
• Cause-and-effect relationships are clearly articulated.
