High Frequency
This topic appears frequently in GCSE Chemistry exams, often combined with sustainability and life cycle assessment questions.
Common Question Types:
- Define/Distinguish [2 marks]: "Explain the difference between a finite and a renewable resource." — Must include timescale and examples.
- Evaluate [4-6 marks]: "Evaluate the benefits and disadvantages of switching from finite to renewable energy sources." — Must balance economic and environmental arguments.
- Suggest [2-3 marks]: "Suggest two ways a manufacturer could reduce the impact of using a finite metal ore." — Recycling, using less, substituting with renewables.
- Classify [1-2 marks]: Given a list of resources, identify which are finite and which are renewable.
Key Points Examiners Look For:
- Reference to timescale (millions of years vs. human timescale) when explaining finite resources
- Specific named examples for both resource types
- Understanding that nuclear fuel (uranium) is finite, not renewable
- Balanced evaluation — renewable resources have limitations too (land use, intermittency)
Quick Check: Is uranium (nuclear fuel) a finite or a renewable resource? Explain your answer.
Uranium is a finite resource. It is a metal ore that must be mined from the Earth's crust and took billions of years to form. Once extracted and used in nuclear reactions, it cannot be replenished on any human timescale.
Quick Check: Give one example each of a finite resource and a renewable resource, and explain why each is classified that way.
Finite example: Coal — formed from ancient plants over millions of years; cannot be replaced once burned. Renewable example: Solar energy — continuously provided by the Sun; replenished on a human timescale (every day).
Quick Check: Suggest two strategies a government could use to extend the lifespan of finite metal resources.
Any two from: (1) Promote recycling of metals — reduces need for new ore extraction. (2) Encourage product design for longevity — products last longer, less material needed. (3) Develop alternative renewable materials — reduces reliance on finite metals. (4) Improve extraction efficiency — less ore wasted per unit of metal produced.
