NOTE

RESOURCES FROM NON-LIVING THINGS
Natural Resources: Natural resources are materials or substances found in nature that are essential or beneficial to human life. They are either renewable (like water, sunlight, and wind) or non-renewable (like fossil fuels and minerals).

 

Solid Minerals: Solid minerals are naturally occurring, inorganic substances with a specific chemical composition and structure. They are mined from the earth and are typically used in construction, manufacturing, and other industries.

 

Mineral Resources: Mineral resources are naturally occurring substances (both metallic and non-metallic) that can be extracted and processed for economic value. They include both solid minerals and fossil fuels and are essential for industrial and economic activities.

 

Examples and Personal Uses:

  • Natural Resources:
    • Example: Water
      • Personal Use: Drinking, cooking, cleaning, and agriculture.
    • Example: Sunlight
      • Personal Use: Solar energy generation for household electricity and heating.
  • Solid Minerals:
    • Example: Iron ore
      • Personal Use: Used to create tools, household items, and appliances through steel production.
    • Example: Limestone
      • Personal Use: Used in building materials like cement for construction purposes.
  • Mineral Resources:
    • Example: Petroleum
      • Personal Use: Fuel for transportation and heating, and as a base for various products like plastics and chemicals.
    • Example: Gold
      • Personal Use: Used in jewelry, electronics, and as an investment asset.

 

EVALUATION:

  1. How do natural resources impact daily life and personal well-being?
  2. What are the differences between solid minerals and other types of mineral resources in terms of their extraction and personal use?
  3. How do solid minerals contribute to the construction and manufacturing industries?
  4. What are the environmental and economic impacts of extracting mineral resources?
  5. In what ways do renewable natural resources differ in personal use from non-renewable mineral resources?

CLASSWORK: As in evaluation

CONCLUSION: The teacher marks their books and commends them positively
