Important Keywords
The following keywords are important for understanding the chapter.
| Keyword | Meaning |
|---|---|
| Natural Resource | A useful material obtained directly from nature. |
| Renewable Resource | A resource that can be naturally replenished. |
| Non-renewable Resource | A resource available in limited quantity that cannot be replaced quickly. |
| Conservation | Careful use and protection of natural resources. |
| Biodiversity | Variety of living organisms found in an area. |
| Afforestation | Planting new trees to increase forest cover. |
| Deforestation | Large-scale cutting of forests. |
| Rainwater Harvesting | Collection and storage of rainwater for future use. |
| Fossil Fuel | Fuel formed from the remains of ancient plants and animals. |

Types of Natural Resources
Natural resources are broadly classified into renewable and non-renewable resources.
| Renewable Resources | Non-renewable Resources |
|---|---|
| Can be replenished naturally. | Take millions of years to form. |
| Available again after use. | Available in limited quantity. |
| Cause comparatively less pollution. | Excessive use leads to depletion. |
| Examples: Air, Water, Sunlight, Wind. | Examples: Coal, Petroleum, Natural Gas, Minerals. |
Air
Air is essential for all living organisms and supports many natural processes.
| Gas | Approximate Percentage | Importance |
|---|---|---|
| Nitrogen | 78% | Supports the nitrogen cycle. |
| Oxygen | 21% | Required for respiration. |
| Other Gases | 1% | Include carbon dioxide, argon, and others. |
Importance of Water
Water is one of the most valuable natural resources.
- Essential for drinking.
- Required for cooking.
- Used in agriculture.
- Needed in industries.
- Supports all living organisms.
Water Conservation
