– The Big Questions
1. How do we categorise natural resources?
👉 On
the basis of use:
- 🌬️
Essential for life → Air, Water, Soil
- 🪵
Materials → Wood, Metals
- ⚡ Energy →
Coal, Sunlight
👉 On
the basis of renewability:
- ♻️ Renewable →
Solar, Wind
- ❌ Non-renewable →
Coal, Petroleum
2. What is the connection between the
distribution of natural resources and different aspects of life?
👉
Effects:
- 🏠
People settle where resources are available
- 🏭
Industries develop near resources
- 🚢
Trade increases between regions
- ⚔️ Conflicts may
occur (water, minerals)
3. What are the implications of unsustainable
use / over-exploitation of natural resources?
- 🌫️
Pollution
- 🐾
Loss of biodiversity
- 🌡️
Climate change
👉
Example:
