Social Science (087) — AI-generated practice question

Nuclear energy is classified as a non-conventional source because the textbook explicitly places atomic energy in this category alongside solar, wind, tidal, geothermal, and biogas energy. The key distinction is the method of energy generation: conventional sources like coal, petroleum, and natural gas are fossil fuels formed over millions of years by burning carbon-based material. Nuclear energy, however, is obtained by altering the structure of atoms (fission), releasing enormous heat to generate electricity — a fundamentally different process. Unlike fossil fuels, it does not involve combustion of organic matter, and its classification is based on the nature of the energy process, not solely whether the fuel is mined.

• The examiner expects you to use the textbook's own definition: nuclear energy is placed under non-conventional sources in the chapter — state this directly.
• The core justification is the process difference: fossil fuels burn carbon; nuclear energy works by altering atomic structure — quote or paraphrase this from the passage.
• Don't get confused by the fact that uranium/thorium are mined minerals — the classification is based on the energy conversion method, not the physical origin of the fuel.
• Avoid writing a long essay; 3 marks = 3 distinct points, tightly stated.
