Study Notes

Natural Resources: Definition and Classification

  • Natural resources are substances found on Earth, formed through natural processes without human intervention.
  • This distinguishes them from resources produced by human actions (e.g., crops).
  • Some are ancient (e.g., minerals), while others are continuously renewed (e.g., water).
  • They are vital for human needs including food, energy, clothing, etc.
  • Their use has driven societal advancement.
  • Examples include air, water, metals, and fossil fuels.

Types of Natural Resources

  • Renewable vs. Nonrenewable:
    • Renewable (sustainable):
      • Abundant or rapidly replenished (e.g., wind, forests).
      • Typically less costly and less environmentally damaging.
    • Nonrenewable (exhaustible):
      • Present in limited quantities or take long to renew (e.g., minerals, fossil fuels).
      • Usually more costly and environmentally impactful
  • Biotic vs. Abiotic:
    • Biotic: From living organisms (e.g., plants, animals).
      • Typically renewable (e.g., crops).
      • Some biotic resources from decaying matter are nonrenewable (e.g. fossil fuels).
    • Abiotic: From non-living sources (e.g., minerals, water).
      • Can be renewable (e.g., air, water) or nonrenewable (e.g., gold).

Importance of Natural Resources

  • Crucial for human survival (water, air, land).
  • Essential for various industrial, commercial, and societal activities.
  • Support economic growth through raw materials and trade.
  • Conservation is essential for future generations to avoid depletion.
  • Sustainable practices (e.g., renewable energy) are vital for minimizing impact.

Key Natural Resource Examples

  • Air: Essential for life.
  • Water: Crucial for survival and various uses.
  • Soil: Supports agriculture.
  • Iron: Used in numerous applications (tools, buildings, cars).
  • Forests: Provide wood, clean air, and habitats.
  • Other examples: minerals, fossil fuels, stone, animals, plants, sunlight.
  • Gold: An abiotic, nonrenewable resource used for jewelry and other items.
