Practice questions

1 of 33Practice questions for this set
A coastal city increased electricity use for air conditioning during hotter summers. The electricity comes mostly from a natural-gas power plant that uses seawater for cooling and then releases the warmed water back to the ocean. Evidence:
  • City electricity demand on hot days: 30% higher in 2023 than in 2013
  • Power plant cooling-water released back to the ocean: +25% volume on hot days (2023 vs 2013)
  • Ocean temperature near the outlet: 1–2°C warmer than nearby water during peak demand hours
Which explanation best connects the consumption pattern to an Earth system impact? (Impacts depend on the amount and rate of use.)
