Answer Key
Multiple Choice Answers:
- B) Solar energy
- A) Photosynthesis
- B) Combustion of fossil fuels
- B) Chemical energy
True or False Answers: 5. True 6. True 7. False 8. True
Short Answer Guidelines: 9. Geothermal energy is generated by harnessing heat stored beneath the Earth's surface. It is used for heating, electricity generation, and direct use applications. 10. The two main types of energy transfer are conduction (transfer of heat through direct contact) and convection (transfer of heat through fluid movement). 11. Environmental impacts of fossil fuel reliance include air and water pollution, habitat destruction, and contribution to climate change through greenhouse gas emissions. 12. Energy conservation helps to reduce overall energy demand, lower greenhouse gas emissions, and can lead to economic savings, thus contributing to sustainability.
Essay Scoring: Evaluate based on clarity, depth of understanding, organization, and ability to support claims with examples and evidence.
