Why Fossil Fuels are Finite

Formation Process:

  1. Ancient organisms - Plants and marine organisms died millions of years ago
  2. Burial - Layers of sediment buried the organic matter
  3. Pressure and heat - Over millions of years, pressure and temperature converted organic matter
  4. Chemical transformation - Organic compounds became hydrocarbons (oil, gas) or carbon-rich coal

Why they're finite:

  • The formation process takes millions of years - far longer than human civilization
  • We're consuming these resources thousands of times faster than they can form
  • Once burned, the carbon is released as CO₂ and cannot be easily recaptured
  • Known reserves are being depleted faster than new ones are discovered

Quick Recall Flashcards

What are renewable resources?
Materials that can be replenished naturally within human timescales through biological or physical processes. Examples include solar energy, wind, and biomass.
What are finite resources?
Materials that exist in limited quantities and cannot be replaced once used up (at least not within human timescales). Examples include fossil fuels and metal ores.
